Solution
The correct answer is: the pesticide was found to negatively impact wildlife.
Here's why: DDT (dichloro-diphenyl-trichloroethane) was widely used in the United States as a pesticide to control mosquitoes and other insects. However, in the 1960s, it was discovered that DDT was causing significant harm to wildlife, particularly birds. The chemical was causing birds' eggshells to thin, leading to a decrease in bird populations. This discovery, along with other evidence of the environmental harm caused by DDT, led to its ban in the United States in 1972.
