Content: The pesticide treadmill
Agricultural pests, like all other organisms, strive to survive. When farmers expose them to a chemical compound that’s designed to kill them, a few of them invariably survive to reproduce. As a result, the next generation is likely to be resistant to the deadly chemical (after all, their parents had some genetic mutation that allowed them to survive). Thus begins a cycle some environmental scientists call the pesticide treadmill: As farmers and pesticide producers work harder to control pests, they create pests that are harder to control. The pesticide treadmill starts with the development of a new and powerful pesticide, but once it starts, it never ends. Here’s how the cycle goes: Chemists create Pesticide A, which is extremely effective at killing pests. Farmers apply the pesticide to their crops. Most pests die, but a few survive and reproduce.
