Question

Please Help!!

Answer 1

Pesticides and fertilizers improve plant performance, so that the same amount of land can yield more.

However, pesticides can also kill native insects that pollinate the plants, but also the insects that feed other animals, like birds. Pesticides can also pollute drinking water. Fertilizers can also cause algal blooms in water ways, because of the phosphorus and nitrogen.
