anon.  let me fix your doomsday demoralized you.  1 . we have unlimited energy. > oil and gas are hydrocarbons, they are abiotic and produced by the planet. > we already found 1000 years worth of hydrocarbons > if we run out of easy oil, we can tap the next easy massive hydrocarbon - methane - for 200 years  > oil wells slowly refill themselves. energy crisis solved: > we have enough nuclear energy on the planet > we have enough hydro plants and hydro energy > if we run out , our ancestors used electric fields of the planet and atmospheric electricity as sources of energy. > if you stick a pole in the ground, or send a chinese $100 drone up 100 meters, you will get free electricity  > if we run out , 75% of everything is hydrogen - the largest uncontrolled energy releases on the planet were hydrogen bomb explosions that used very little hydrogen. don't worry about energy.  2. we can easily feed 20 billion people right now. 3. we have unlimited wood resources 4. we have unlimited clay resources - we can build millions of brick houses. there's a tech that is hidden from us to build bricks that last thousands of years.  we will be fine.
