3 Preface The Millennium Ecosystem Assessment (MA) was called for by United Nations Secretary-General Kofi Annan in 2000 in a report to the General Assembly entitled We the Peoples: The Role of the United Nations in the 21st Century. Initiated in 2001, the objective of the MA was to assess the consequences of ecosystem change for human well-being and the scientific basis for actions needed to enhance the conservation and sustainable use of those systems and their contribution to human well-being. The MA has involved the work of more than 1,360 experts worldwide. Their findings on the condition and trends of ecosystems, scenarios for the future, possible responses, and assessments at a sub-global level are set out in technical chapters grouped around these four main themes. In addition, a general Synthesis draws on these detailed studies to answer a series of core questions posed at the start of the MA. The practical needs of specific groups of users, including the business community, are addressed in other synthesis reports. Each part of the assessment has been scrutinized by governments, independent scientists, and other experts to ensure the robustness of its findings. This statement is from the Board governing the MA process, whose membership includes representatives from U.N. organizations, governments through a number of international conventions, nongovernmental organizations, academia, business, and indigenous peoples. (For a full list of Board members, see the inside front cover.) It is not intended as a comprehensive summary of the findings of the MA, but rather as an interpretation of the key messages to emerge from it. Written for a non-specialist readership, it is nevertheless consistent with the more detailed documents of the assessment and can be read in conjunction with them. We believe that the wide range of global interests combining to issue this statement, together with the rigorous study on which it is based, should add power and urgency to the conclusions it sets out. The Board of the Millennium Ecosystem Assessment
5 Key Messages Everyone in the world depends on nature and ecosystem services to provide the conditions for a decent, healthy, and secure life. Humans have made unprecedented changes to ecosystems in recent decades to meet growing demands for food, fresh water, fiber, and energy. These changes have helped to improve the lives of billions, but at the same time they weakened nature s ability to deliver other key services such as purification of air and water, protection from disasters, and the provision of medicines. Among the outstanding problems identified by this assessment are the dire state of many of the world s fish stocks; the intense vulnerability of the 2 billion people living in dry regions to the loss of ecosystem services, including water supply; and the growing threat to ecosystems from climate change and nutrient pollution. Human activities have taken the planet to the edge of a massive wave of species extinctions, further threatening our own well-being. The loss of services derived from ecosystems is a significant barrier to the achievement of the Millennium Development Goals to reduce poverty, hunger, and disease. The pressures on ecosystems will increase globally in coming decades unless human attitudes and actions change. Measures to conserve natural resources are more likely to succeed if local communities are given ownership of them, share the benefits, and are involved in decisions. Even today s technology and knowledge can reduce considerably the human impact on ecosystems. They are unlikely to be deployed fully, however, until ecosystem services cease to be perceived as free and limitless, and their full value is taken into account. Better protection of natural assets will require coordinated efforts across all sections of governments, businesses, and international institutions. The productivity of ecosystems depends on policy choices on investment, trade, subsidy, taxation, and regulation, among others. Living Beyond Our Means: Natural Assets and Human Well-being 3
7 Running down the account The bottom line At the heart of this assessment is a stark warning. Human activity is putting such strain on the natural functions of Earth that the ability of the planet s ecosystems to sustain future generations can no longer be taken for granted. The provision of food, fresh water, energy, and materials to a growing population has come at considerable cost to the complex systems of plants, animals, and biological processes that make the planet habitable. As human demands increase in coming decades, these systems will face even greater pressures and the risk of further weakening the natural infrastructure on which all societies depend. Protecting and improving our future well-being requires wiser and less destructive use of natural assets. This in turn involves major changes in the way we make and implement decisions. We must learn to recognize the true value of nature both in an economic sense and in the richness it provides to our lives in ways much more difficult to put numbers on. Above all, protection of these assets can no longer be seen as an optional extra, to be considered once more pressing concerns such as wealth creation or national security have been dealt with. This assessment shows that healthy ecosystems are central to the aspirations of humankind. Natural provisions In the streets of a crowded city, in the aisles of a giant supermarket, or on the floor of a gleaming electronics factory, the biological state of Earth s rivers, forests, and mountains may seem a remote concern. Yet despite the breakneck pace of technological change many of us have seen in our lifetimes, we each depend far more than we may realize on the web of life of which we are a part. The food and fresh water that keep us alive, the wood that gives us shelter and furniture, even the climate and the air we breathe: all are products of the living systems of the planet. As forests and savanna made way for farms, as rivers were diverted to irrigate fields, and as new technology enabled fishing vessels to haul ever-greater harvests from the oceans, the recent changes made to natural systems have helped not just to feed a rapidly growing human population but to improve the lives of billions. In the midst of this unprecedented period of spending Earth s natural bounty, however, it is time to check the accounts. That is what this assessment has done, and it is a sobering statement with much more red than black on the balance sheet. Spending the capital Nearly two thirds of the services provided by nature to humankind are found to be in decline worldwide. In effect, the benefits reaped from our engineering of the planet have been achieved by running down natural capital assets. In many cases, it is literally a matter of living on borrowed time. By using up supplies of fresh groundwater faster than they can be recharged, for example, we are depleting assets at the expense of our children.the cost is already being felt, but often by people far away from those enjoying the benefits of natural services. Shrimp on the dinner plates of Europeans may well have started life in a South Asian pond built in place of mangrove swamps weakening a natural barrier to the sea and making coastal communities more vulnerable. Unless we acknowledge the debt and prevent it from growing, we place in jeopardy the dreams of citizens everywhere to rid the world of hunger, extreme poverty, and avoidable disease as well as increasing the risk of sudden changes to the planet s life-support systems from which even the wealthiest may not be shielded. We also move into a world in which the variety of life becomes ever more limited. The simpler, more uniform landscapes created by human activity have put thousands of species under threat of extinction, affecting both the resilience of natural services and less tangible spiritual or cultural values. Yet this need not be a counsel of despair. The natural balance sheet we bequeath to future generations depends on choices made at every level and in every corner of the planet from the head of a village in Bangladesh to a corporation board in a New York skyscraper; from international gatherings of finance ministers to consumers in a Brazilian furniture store.

8 The services of nature Essential to our lives As human societies become more and more complex and technologically advanced, it is easy to gain the impression that we no longer depend on natural systems. A steadily increasing proportion of the population lives in cities, in environments dominated by human-built structures and machines. Nature may appear to be something to be enjoyed at the weekend if we get the chance, nice to have but hardly at the forefront of our daily concerns. Even in rural areas, the conservation of natural spaces is often seen as a luxury that has little to do with the well-being of local people a swamp, for example, might be viewed as wasted land, whose only value is in the crops that could be planted if it were to be drained. These are dangerous illusions that ignore the vast benefits of nature to the lives of the 6 billion people on the planet. We may have distanced ourselves from nature, but we rely completely on the services it delivers. Ecosystems and Some Services They Provide Different combinations of services are provided to human populations from the various types of ecosystems represented here. Their ability to deliver the services depends on complex biological, chemical, and physical interactions, which are in turn affected by human activities. 6 Living Beyond Our Means: Natural Assets and Human Well-being
9 Providing the basics At the most basic level, the food we eat is a service of nature. This is most obviously true when it is obtained by harvesting wild species such as ocean fish: the healthy functioning of the food chain of the seas is an asset of vast economic value. Even food grown in what appear to be the most unnatural conditions, however, is still a product of the biological processes of nature. Whether it is in the genetic material from which seeds or livestock are bred (or, with biotechnology, altered), the soils in which crops are grown, or the water that makes the land fertile: human nourishment depends on a natural infrastructure underlying the skills and technology of farmers around the world. Apart from its role in food production, fresh water is of course another of the basics of life. For all the ingenious channeling techniques developed since the earliest civilizations, we still rely on natural systems to regulate the flow of water through the river basins of the world. Even with the invention of many synthetic materials, other products of nature are still used in huge quantities in every society trees bring us wood and paper, the fashion industry needs plant and animal fibers, and medicines derived from nature are in ever-greater demand. Regulating Earth nature as life support While the value of most of these products can be fairly easily calculated, many other services of nature do not appear on conventional balance sheets, but they are equally essential for the survival of modern economies. Their true worth is often appreciated only when they are lost. Linkages between Ecosystem Services and Human Well-being Living Beyond Our Means: Natural Assets and Human Well-being 7
10 Annual Flow of Benefits from Forests in Selected Countries The value of a forest is often measured only by the timber and fuel provided by its trees. In these countries, however, that is generally less than one third of the total economic value. The higher figure includes services such as control of the climate through absorption (sequestration) of carbon dioxide, protection of freshwater sources (watersheds), and recreation. Because many of these services are not bought and sold in markets, they are frequently lost or degraded even though their value to human societies is high. 8 Living Beyond Our Means: Natural Assets and Human Well-being
11 Returning to that apparently worthless swamp, for example, wetlands perform a wide range of functions of great value to people from acting as a natural pollution filter and preventing floods by storing water during heavy rains to supporting wildlife and recreation. Forests help regulate air quality, the flow of water, and the climate itself. Although their relationship with the atmosphere is more complex than the common description as lungs of the earth, forests store large quantities of carbon that would add to the greenhouse effect if released into the air. Natural systems provide protection from a range of catastrophic events that can devastate human communities vegetation helps prevent soil erosion and reduce the likelihood of landslides, while coral reefs and mangrove forests act as barriers against coastal storms and even tidal waves. Interference with living systems can also promote the sudden emergence of human diseases and crop pests, causing great suffering and economic damage. In attempting to assess the importance of nature to our lives, we should not lose sight of the value placed on the variety of life on Earth for its own sake: this is even more difficult to put a price on, but nonetheless of deep concern to people of all cultures. Whether it is the uplifting sound of birdsong in a city park, the reverence for local species in many indigenous belief systems, or the wonder of a child watching wildlife in a zoo or even on television, appreciation of the natural world is an important part of what makes us human. Even if our material needs could be met with a much narrower range of species and landscapes, many people would regard this loss as a significant threat to their overall well-being. Economic Benefits under Alternate Management Practices In each case, the net benefits from the more sustainably managed ecosystem are greater than those from the converted ecosystem when measurements include both marketed and nonmarketed services, even though the private (market) benefits would be greater from the converted ecosystem.

12 Facts and Figures of Ecosystem Change Water withdrawal and impoundment Water withdrawals from rivers and lakes for irrigation, household, and industrial use doubled in the last 40 years. Humans now use between 40% and 50% of the fresh water running off land to which the majority of the population has access. In some regions, such as the Middle East and North Africa, humans use 120% of renewable supplies (due to the reliance on groundwater that is not recharged). Between 1960 and 2000, reservoir storage capacity quadrupled and, as a result, the amount of water stored behind large dams is estimated to be three to six times the amount held by natural river channels (this excludes natural lakes). CREDIT: RON GILING/PETER ARNOLD, INC. CREDIT: ICARDA Conversion and degradation More land was converted to cropland in the 30 years after 1950 than in the 150 years between 1700 and 1850, and now approximately one quarter (24%) of Earth s terrestrial surface has been transformed to cultivated systems. Nutrient use and levels Human activities now produce more biologically usable nitrogen than is produced by all natural processes combined, and more than half of all the manufactured nitrogen fertilizer (first produced in 1913) ever used on the planet has been applied since Since about 1980, approximately 35% of mangroves have been lost, while 20% of the world s coral reefs have been destroyed and a further 20% badly degraded or destroyed. The flow of nitrogen to the oceans has doubled since The use of phosphorus fertilizers and the rate of phosphorus accumulation in agricultural soils both increased nearly threefold between 1960 and Although the rate has declined somewhat since then, phosphorus can remain in soils for decades before entering the wider environment. Fisheries At least one quarter of marine fish stocks are overharvested. The quantity of fish caught by humans increased until the 1980s but is now declining because of the shortage of stocks. In many sea areas, the total weight of fish available to be captured is less than a tenth of that available before the onset of industrial fishing. Inland fisheries, especially important for providing highquality diets for the poor, have also declined due to overfishing, changes to habitats, and withdrawal of fresh water. 10 Living Beyond Our Means: Natural Assets and Human Well-being
13 Pressures and Changes The historical context The development of human societies has been a story of changing the natural systems of the planet to sustain ever-more sophisticated and comfortable ways of living and ever-greater numbers of people. In early civilizations, the transition to complex social and political structures was often closely linked to major projects engineering those systems for human advantage, such as clearing forests to make way for agriculture and diverting rivers to irrigate crops. Over the millennia, areas of wilderness were adapted across the planet to enable settled communities to enjoy a secure supply of food, water, energy, and materials. Demand for luxuries in one part of the world could influence natural systems thousands of miles away for instance, the European taste for sugar and the red textile dye produced from brazilwood changed forever the Atlantic Forest of South America. With the onset of industrialization, the pace of these changes accelerated as new technology and medical advances made possible the sustenance and survival of rapidly growing urban populations. Yet throughout human history, no period has experienced interference with the biological machinery of the planet on the scale witnessed in the second half of the twentieth century. The Nitrogen Cycle Human activities, including farming and industry, have greatly increased the cycle of nitrogen through soils, water courses, and the atmosphere. By accumulating more nitrogen in a form that can be taken up by plants, the balance of ecosystems can be seriously upset. Living Beyond Our Means: Natural Assets and Human Well-being 11
14 Re-engineering the planet Between 1950 and 1980, more land such as forest, savanna, and natural grassland was converted to cropland than in the eighteenth and first half of the nineteenth centuries combined. Nearly a quarter of the land surface of Earth is now cultivated. Accompanying this change has been a huge increase in the application of manufactured nitrogen and phosphorus fertilizers. These nutrients are targeted at crops, but in effect they have also fertilized nature as they are washed into streams, rivers, and eventually the oceans. In many places this has led to excess growth of plants such as algae that in turn deprive the water of oxygen and kill other forms of aquatic life. The amount of water taken from rivers and lakes to irrigate fields, to meet the needs of industry, and to supply households has doubled since The quantity impounded behind dams has quadrupled in the same period, and artificial reservoirs now hold much more water than free-flowing rivers do. Global Trends in the Creation of Reactive Nitrogen (That Available to Living Organisms) by Human Activities, with a Projection to 2050 As a result, the flow of some rivers has been substantially reduced. At times the Yellow River in China, the Nile in Africa, and the Colorado in North America do not even reach the ocean. Rivers now transport much less of the sediments that bring food supplies to estuaries and help support vibrant populations of shellfish, fish, and birds. In some areas, however, soil erosion produces an oversupply of sediment, which can cause considerable damage to the local ecology. The development of coastlines for tourism and activities such as shrimp farming has also dramatically altered the meeting point of land and ocean. In just two decades, it is estimated that people have removed more than a third of the world s mangroves the dense forests growing in the tidal mud of many tropical regions. It will probably never be known how many lives were lost in the Indian Ocean tsunami due to the loss of mangroves and damage to coral reefs, but it has been widely accepted that areas with less damage to the natural coastline were better protected from the force of the tidal wave. The unchanging appearance of the ocean itself belies a major shift in the systems of life hidden beneath the waves, due mostly to the human appetite for fish and the increasing technological efficiency of the fishing industry. The full consequences of this pressure are still poorly understood, but a recent study estimated that 90% of the total weight of large predators of the ocean such as tuna, swordfish, and sharks has disappeared in modern times. Moving species Another major change might be termed the globalization of nature. As people become increasingly mobile, plants and animals have been transported to parts of the world where they never previously existed, entering the local web of life and sometimes altering it profoundly. Often this has been deliberate, such as the introduction of domestic livestock or crop species the unique wildlife of some of the Galapagos Islands, for example, has been severely affected by the arrival of goats. In many cases, however, it has been an accidental impact of the accelerating human links across the planet. Ocean-going freight ships carry large numbers of sea creatures in their ballast tanks, which are flushed out at their destination as they load up their holds. This has led to some remarkable exchanges of species. The Baltic Sea, for instance, contains 100 creatures from outside the region, a third of which are native to the North American Great Lakes. And a third of the 170 alien species in those lakes are native to the Baltic. Such changes are more than just a question of the purity of nature. A species introduced from outside can dramatically change the local system and the services it provides for example, the arrival of the American comb jellyfish in the Black Sea led to the destruction of 26 commercially valuable stocks of fish. 12 Living Beyond Our Means: Natural Assets and Human Well-being
15 Changing the climate The change with the greatest potential to alter the natural infrastructure of Earth is the chemical experiment humans have been conducting on the atmosphere for the past century and a half. The dominance of coal, oil, and natural gas as our sources of energy has released large quantities of carbon previously locked in underground rock layers and has increased the amount of carbon dioxide gas in the air by about a third. It is now well established that this has changed global weather systems by trapping more of the Sun s heat within the atmosphere, and that these changes will accelerate as the concentration of carbon dioxide continues to grow. Nature has always adapted to changes in climate, but this shift is likely to pose unprecedented challenges to its resilience for two main reasons. First, the anticipated speed of climate change is greater than anything seen for at least 10,000 years, making it far more difficult for species to move to more suitable areas or adapt to the new conditions by evolving new survival mechanisms. Coral reefs, for example, have already become barren in some areas through relatively modest increases in sea temperatures, combined with other pressures such as nutrient pollution and overfishing. Just as important, the options available to plants and animals have been greatly narrowed by the massive changes humans have Invasive Species around the World Living Beyond Our Means: Natural Assets and Human Well-being 13

17 made to the landscape. Many species are in effect locked into islands of nature surrounded by urban or intensively farmed regions, shutting off escape routes and making them highly vulnerable to climate change. Reducing diversity An outcome of all these changes has been to reduce significantly the variety of species that can be found in many individual areas and on the planet as a whole. Converting rainforest into cropland, river banks into reservoirs, or marshes into parking lots will not end all natural processes, but it will tend to produce a less diverse landscape excluding many of the species previously occupying the space. We cannot be precise about the overall scale of the change, since it is estimated that science has only identified some 10% of the species on Earth. However, we can say that the majority of species across a range of different categories such as amphibians, farmland birds, and Caribbean corals are declining in abundance or in the area occupied by their populations. Some 12% of birds, 25% of mammals, and at least 32% of amphibians are threatened with extinction over the next century. Although actual disappearance of a recognized species is quite rare in terms of human time scales, it is estimated that people may have increased the rate of global extinctions by as much as 1,000 times the natural rate typical of Earth s long-term history. Species Extinction Rates Comparisons with the rate at which species have disappeared from the planet over a long period of Earth s history indicate that humans have already increased extinction levels dramatically. Projections suggest this rate will take another big leap due to changes over the next 50 years. The bars represent the range of estimates in each case.

18 The balance sheet the state of nature s services In credit food production The Millennium Ecosystem Assessment is the first attempt by the scientific community to describe and evaluate on a global scale the full range of services people derive from nature. In all, it has been able to provide a health check on 24 of those services others were identified, but the information was not available to make a sensible judgment on their status. Only 4 of the services were found to be increasing their ability to benefit human populations, while 15 were in decline. Five more were found to be in a stable state overall, but in trouble in some parts of the world. On the credit side, three of the improving services reflect the worldwide efforts to keep food supply ahead of the increase in population total food production increased by about two-and-a-half times while the number of people in the world doubled from 3 billion to 6 billion between 1960 and So the landscapes of the planet were able in recent decades to yield far more crops and meat through a combination of turning more land over to agriculture and harvesting more grain or fattening more animals on each hectare. Another way of providing food has also seen a dramatic increase in recent years the farming of fish or shellfish, from salmon cages in the sea lochs of Scotland to shrimp farms in Thailand or carp ponds in China. This now accounts for nearly a third of all fish and shellfish production on the planet. In debit running short of stock Some of the clearest evidence of the pressure we are putting on nature comes in services such as wild fish and fresh water. People have always relied on Earth s systems to replace what we take of these items. In effect, they have been treated as free gifts, with their supply limited only by the technology and effort needed to capture more for our use. In both cases, the signs are flashing red, with strong indications in many areas that we have gone past the point where nature can replenish the stock. For ocean fish, that evidence comes simply from the fact that fishing vessels are catching less in their nets, despite and, in a sense, because of their improved technology. Worldwide fish landings peaked in the 1980s and are now declining, even though demand has never been greater and will continue to rise according to all the plausible futures investigated during this assessment. In many sea areas, the weight of fish available to be harvested is calculated to be less than one tenth or even one one-hundredth of what it was before the introduction of industrial fishing. The decline of stocks is depriving many poor communities of valuable sources of protein. CREDIT: FAO PHOTO BY T. JANSSEN This is not helped by arrangements such as the European Union s practice of paying West African countries for access to their territorial waters, leaving small-scale traditional vessels to compete for dwindling stocks with giant super-trawlers themselves often built using subsidies from European taxpayers. For fresh water, there is no worldwide shortage even after doubling our consumption we use roughly 10% of the water that flows from source to sea. But the supply is very unevenly distributed across the world and over time. The pattern of use in some areas simply cannot continue into the long term. Up to a quarter of the water supplied to human communities is being used in larger quantities than local river systems can provide. To make up the shortfall, supplies either have to be transferred from other regions through major engineering works or mined from underground sources that are not replaced. In either case, current water consumption is only able to continue by shifting the problem to distant communities and natural systems or to future generations. 16 Living Beyond Our Means: Natural Assets and Human Well-being
19 Global Status of Ecosystem Services Evaluated in the MA An upwards arrow indicates that the condition of the service globally has been enhanced and a downwards arrow that it has been degraded. Definitions of enhanced and degraded for the three categories of ecosystem services shown in the table are provided in the note below. Supporting services, such as soil formation and photosynthesis, are not included here as they are not used directly by people. Service Sub-category Status Notes Provisioning Services Food crops substantial production increase livestock substantial production increase capture fisheries declining production due to overharvest aquaculture substantial production increase wild foods declining production Fiber timber +/ forest loss in some regions, growth in others cotton, hemp, silk +/ declining production of some fibers, growth in others wood fuel declining production Genetic resources lost through extinction and crop genetic resource loss Biochemicals, lost through extinction, overharvest natural medicines, pharmaceuticals Fresh water unsustainable use for drinking, industry, and irrigation; amount of hydro energy unchanged, but dams increase ability to use that energy Regulating Services Air quality regulation decline in ability of atmosphere to cleanse itself Climate regulation global net source of carbon sequestration since mid-century regional and local preponderance of negative impacts Water regulation +/ varies depending on ecosystem change and location Erosion regulation increased soil degradation Water purification and declining water quality waste treatment Disease regulation +/ varies depending on ecosystem change Pest regulation natural control degraded through pesticide use Pollination a apparent global decline in abundance of pollinators Natural hazard regulation loss of natural buffers (wetlands, mangroves) Cultural Services Spiritual and religious values rapid decline in sacred groves and species Aesthetic values decline in quantity and quality of natural lands Recreation and ecotourism +/ more areas accessible but many degraded Note: For provisioning services, we define enhancement to mean increased production of the service through changes in area over which the service is provided (e.g., spread of agriculture) or increased production per unit area. We judge the production to be degraded if the current use exceeds sustainable levels. For regulating services, enhancement refers to a change in the service that leads to greater benefits for people (e.g., the service of disease regulation could be improved by eradication of a vector known to transmit a disease to people). Degradation of regulating services means a reduction in the benefits obtained from the service, either through a change in the service (e.g., mangrove loss reducing the storm protection benefits of an ecosystem) or through human pressures on the service exceeding its limits (e.g., excessive pollution exceeding the capability of ecosystems to maintain water quality). For cultural services, degradation refers to a change in the ecosystem features that decreases the cultural (recreational, aesthetic, spiritual, etc.) benefits provided by the ecosystem. a Indicates low to medium certainty. All other trends are medium to high certainty. Living Beyond Our Means: Natural Assets and Human Well-being 17
20 In debit the fabric of life The assessment also found deterioration of a wide range of natural services essential to the functioning of human societies. The loss of wetlands combined with increased pollution has reduced the ability of natural systems to cleanse water supplies, with major implications for human health and fisheries. Ecosystems are losing their ability to maintain a stable local climate for example, loss of plant cover and deforestation can lead to less rainfall in tropical regions. There are signs that damage to natural systems has reduced the number of insects and birds available to carry the pollen needed for flowering plants to reproduce, with serious implications for many crops. Marine Fisheries The dramatic collapse of cod stocks off Newfoundland illustrates how quickly the services of an ecosystem can disappear when its resources are overexploited. The protection provided to people by natural systems against extreme events is in decline. For instance, there have been significantly more floods in recent years, not just due to heavier rainfall, but also through landscape changes such as deforestation and the draining of marshes removing natural storage areas and forcing more water through the narrow channels into which rivers are often now confined. Shocks and surprises If natural systems were well understood and behaved in a predictable way, it might be possible to calculate what would be a safe amount of pressure to inflict on them without endangering the basic services they provide to humankind. Unfortunately, however, the living machinery of Earth has a tendency to move from gradual to catastrophic change with little warning. Such is the complexity of the relationships between plants, animals, and microorganisms that these tipping points cannot be forecast by existing science. Abrupt changes can have devastating impacts on human communities. The buildup of nitrogen and phosphorus in lakes, estuaries, and enclosed seas, for example, can continue for years before suddenly triggering an explosive growth of algae. Climate change also has the potential to tip natural systems quickly over the edge. Some models suggest that global warming could turn the Amazon from lush forest to dry savanna, with devastating impacts including further instability of the regional and global climate. Once such trigger points are reached, it can be difficult or impossible for natural systems to return to their former state: more than a decade after the sudden collapse of cod stocks on the Grand Banks off Canada, for example, there are few signs of the fish returning even though the main fishery has been closed for 13 years. Even if these changes cannot be predicted, the scientists involved in this assessment conclude that our current behavior makes it likely that more will occur in future. We are lowering the resilience of natural systems by simultaneously reducing the variety of species and placing them under unprecedented pressures. Investing in the health of natural assets could therefore be seen as a form of prudent insurance against abrupt changes and the risk to human well-being that they pose. 18 Living Beyond Our Means: Natural Assets and Human Well-being

AT first, Michel Richard did not want to come clean about his secret passions. "You'll write it in the newspaper and everyone will know," said the chef at the highly acclaimed Citrus in Los Angeles with assorted outposts around the country.
The man who can have sauteed foie gras with a crispy potato crepe or rack of lamb with sun-dried tomato and pimiento gnocchi by snapping his fingers eats hot dogs, frozen french fries, salami and lemon chicken from a nearby Chinese restaurant. Right now he is stealthily making his way through a cheesecake in the freezer at home. "I'm sure one day my wife will go in there and find nothing in the box," he said.
Mr. Richard is no quirkier than many other professional chefs. Surrounded by superb dishes that have customers clamoring for more, they have secret longings for the foods other people can eat openly. These chefs have a fondness for dishes that wouldn't find house room with many of their customers: things like Domino's pizza, Gummy Bears and Gatorade.
These are their comfort foods, though not necessarily the foods they grew up with.
Mr. Richard, who answered the phone one day last week by saying: "I'm starting my diet today," said, "I think I love everything." He starts each morning with a scoop of frozen yogurt or sorbet. "I stopped eating cereal when I found a fly in it." Some excuse.
On his way home from Citrus on evenings when he can leave early because business is slow, he stops at the Chinese restaurant and eats lemon chicken accompanied by Gatorade, the only drink the restaurant serves that he likes.Continue reading the main story
The hot dogs -- of the turkey variety -- are eaten with his six children, and there is a French twist. Mr. Richard uses an old French hot-dog machine that toasts baguettes (not hot-dog rolls) and steams the franks. The mustard of choice is Dijon. The French fries, if not frozen, are picked up from McDonald's.
Just talking about food makes Mr. Richard hungry. "I've changed my mind," he said at the end of the conversation. "I'm not going on a diet until tomorrow morning."
When Eric Ripert, the chef at Le Bernardin, the four-star restaurant in New York, heard that Mr. Richard ate hot dogs, he said: "That's bad. I'm much better than Michel."
Mr. Ripert's indulgence of choice is candy. Not Godiva chocolates or Teuscher's truffles but Gummy Bears, jelly beans, licorice, Mentos and tiny Snickers. "I'm very good at work," said Mr. Ripert, who tries not to eat at the restaurant. "But when the cookies are coming back from the dining room, I pick off the chocolate and the cheesecakes." Off the trays, not the customers' plates.
He also dips his hand into his ever-present candy jar. "I try to do it only once but . . . ," he said, his voice trailing off. "I've always loved candy. When I was a child, the dentist was afraid I would lose my teeth. Every day I say I'm going to be good, but by the end of the night I can't be anymore. Right now talking to you I am salivating, and as soon as I hang up I'm going to the candy jar."
In Boston, Lydia Shire can't take her eyes off the chicken and duck butts (more delicately known as rumps) as rows of them are carried from the ovens, succulent and golden brown. As soon as Ms. Shire, the chef and owner of Biba and Pignoli, two of Boston's hot spots, sees them she gets out her knife, performs surgery, and starts eating. "The greatest things to eat, in order, are fat and salt," Ms. Shire said. "If I see a tray of 16 chickens, I've been known to eat six or seven of the butts with salt. Skin in combination with salt." She sighed with satisfaction.
At home, where chicken rumps are not a dime a dozen, Ms. Shire opts for a mayonnaise sandwich. And it must be Hellman's. "No other mayonnaise will do," she said. "If you're American and grew up in America, you want Hellman's when you have a craving because you aren't going to stop to make mayo." Any kind of bread will do, and even crackers.
Alas, Ms. Shire plans to give up rumps and mayonnaise sandwiches soon. "I have to fit into a wedding dress in September," she said. "I'm going to have to start living on a memory."
At least temporarily.
Even Dean Fearing, the executive chef at the elegant and expensive Mansion on Turtle Creek in Dallas, has had to cut back on his a two-or-three-times-a-week Domino's pizza habit. "Now it's a Friday or Saturday night item, because I'm trying to get into my 34 pants," he said. "I have one pair of 36 and 10 pairs of 34, and now I can't get in them."
Domino's has been delivering pizzas to Mr. Fearing and his wife, Lynae, for so long now the pizza makers know just which toppings to include. But they wouldn't recognize their work after Mr. Fearing gets through with it. He adds fresh basil, tons of black pepper, a sprinkling of thyme, some good Romano or Parmigiano Reggiano, and then Robert del Grande's "voodoo" sauce, a red-chili sauce made by his friend, the chef and owner of Cafe Annie in Dallas. (Both men are equally well known for their world-class American southwestern food.)
"It makes Domino's pizza stand up and scream," Mr. Fearing said. "When I get home at night, I'm tired of eating restaurant food. If I brought it home it would be like bringing home work from the office."
On nights when he feels like cooking, he may add a bowl of pasta to his repast. The sauce is made with onion, mushrooms, cabbage, lots of garlic, basil, thyme and plenty of serrano chilies. When the pasta is ready, it is added directly to the pot.
Roberto Donna is a chef whose secret passion is more costly than anything he serves at his finest restaurant, Galileo, but he doesn't like to talk about it. Maybe that's because he lives in Washington, where personal peccadilloes are best kept out of the news. "If I tell you," said Mr. Donna, who owns five other restaurants, "everyone on my staff will want it."
His very expensive habit reminds him of his childhood in the Piedmont region of Italy, renowned for its glorious white truffles that perfume dishes each fall, sending aficionados into raptures. Mr. Donna's dream dish is white-truffle risotto -- with more truffles than rice. "I don't want anyone to see me eat this," Mr. Donna said with a giggle, "because it gets very expensive and the customers will want me to make it and my employees will want it. I can charge the customers but I can't charge employees."
With the six to eight ounces of truffles he puts in the risotto, the cost for him last fall, when truffles were in season, was about $250 to $325 a serving. The price would have been double for his customers.
"It's truffles with risotto," he said. "It's not risotto with truffles. That's how I really enjoy truffles." Who wouldn't?
Still, it is much easier to explain white truffles to your sophisticated clientele than duck butts or Gummy Bears.Continue reading the main story
