How can pesticides be good?

Answer 1

they kill the very things that kill our plants and makes ourlawns weed free. the bad thing is constant use of them, lead to COPD which destroys air sacks in your lungs.take it from me . give me a crappy lawn and small harvests from your backyard garden and let me breath again.

A better question is how could the use of them be bad!? Pesticides can certainly be overused, but the correct use allows people to live their lives free from disease and with full stomachs.

Without pesticides, wars could have been lost, food far less plentiful, whole areas would be uninhabitable. Disease would be rampant and our food supply much more scare and less stable. Eating could become an adventure as to what disease you could contract.

A great example is the banning of DDT. malaria was almost completely eradicated through the use of DDT. The banning if this chemical has caused millions of deaths with the diseases resurgence.

Answer 3

Properly used, pesticides have a very low risk of harm. Accidental ingestion can, of course, make a human or any animal quite ill, and can even be fatal. Remember that a pesticide is "any substance or mixture of substances intended for preventing, destroying, repelling, or mitigating any pest. Pests can be insects, mice and other animals, unwanted plants (weeds), fungi, or microorganisms like bacteria and viruses." So even your household disinfectant is a pesticide.

The question is too general to be answered further.
