About the Book Author

Content: A new generation of pests that aren’t affected by Pesticide A is born. Farmers apply Pesticide A with little or no result now that the pests are resistant. Chemists create a newer, more powerful compound, Pesticide B.
The cycle repeats itself over and over again. The pesticide treadmill leads to increasing costs for farmers, who have to purchase new pesticide formulas every year or risk losing their crops. Plus, each generation of pests is increasingly more difficult to kill, meaning that the pesticides chemists develop to kill the new pests must be even more potent than the last ones. Spreading pesticide poisons in the environment
Not all pesticides are manmade. Some, such as botanical extracts and oils, are naturally occurring compounds. Naturally occurring pesticides are still extremely toxic and can affect both the humans and the pests that are exposed to them. However, naturally occurring pesticide compounds eventually break down and recycle back through the ecosystem, whereas manmade compounds often do not. Scientists categorize synthetic or manmade pesticides according to their chemical structure.
