This discussion post will have you examine whether or not we should use pesticides, the impacts pesticides have and have had on the environment, and the potential for short-term and long-term impacts.  The questions I want you to answer are:

Are there benefits or hazards from using pesticides?  Such as? 
Weigh the pros and cons to pesticide use.
What are the environmental impacts, both pro and con, and what are the health impacts?
