1) A pesticide is a chemical used to kill pests, especially insects. A pest is a destructive insect or other animal that attacks crops, food, livestock, etc.
====If you use lady bugs to eat the harmful insects, that is biological pesticide. If you import birds that eat the specific pest, that is biological pesticide. If you use a chemical whether it is made in the lab or natural, that is a chemical pesticide. :)==== ====2) Pesticide use can has saved millions of lives. With respect to agriculture- 35% lost before cropping and 20% post with pesticides ; without pesticide **another 8% of additional damage** would occur according to==== [] :) These are both very logical reasons pesticed use is good for the world. The downside of pesticide use would be poisoning humans.Each year WHO estimates 1-5 million people have **acute poisoning**and die. In the US, 20,000 are estimated to suffer from some form of pesticide poisoning. Another downside is pesticide use has threatened and continues to impact wildlife negatively.

3) Letting a certain predator into an enviroment is a safe way to control, but it has to be controlled. For example, you could put a snake into and infested pond. :)
