Answer #1

The impacts of insecticide and pesticides are majorily seen on non-target species. Insecticides are chemical preparations used to kill fungus or animal pests harming the crop. About 95% of these insecticides reach their non target species as they are widely spread over the agricultural fields.

Animals and natural predators get poisonied due to their residues left over the plant parts of crop. Insecticides eliminate the food sources, causing the animals to shift or starve to death. They even reaches water bodies and affects the aqauatic ecosystem thus leading to eutrophication and ultimately algal bloom. These chemicals on reaching food chain harms the top consumers due to the process of bioaccumulation, thus, harming even humans. Decrease in number of natural predators led to reduction in check of pests population, thus, leading to severe crop damage.
