Question

Which of the following changes should be implemented to help achieve sustainable farming while also protecting the environment?

Answer 1

Answer:

Using predatory insects to control pests that destroy crops instead of pesticides

Explanation:

For example, you can use lady bugs to get rid of Aphids.  Many predatory bugs can be used to eliminate bugs that will eat crops.

Answer 2

I'd say that the option which should be implemented to help achieve sustainable farming while also protecting the environment is the last one - using predatory insects to control pests that destroy crops instead of pesticides.
This is the natural course of life - instead of using pesticides which are harmful to the land, you should use these insects which do not hurt it.
