Compare the benefits and environmental impacts of pesticide use.
asambeis [7]

Answer:

<u>Benefits</u>:

pesticides can keep harmful pests–such as rats, mice, ticks and mosquitoes–away from crops while also protecting the plants from weeds and diseases that have the ability to greatly reduce crop yield.

<u>Environmental impacts</u>:

Pesticides may move with runoff as compounds dissolved in the water or attached to soil particles. Runoff from areas treated with pesticides can pollute streams, ponds, lakes, and wells. Pesticide residues in surface water can harm plants and animals and contaminate groundwater.
