I don't understand how scientists could think that chemicals that prove

harmful to wildlife would not be harmful to humans....I mean, we are all

biological systems!!!

For some reason, this dangerous view that humans are not suscepible to the

harmful effects of chemicals in the way that wildlife has been permeates

America---to our detriment. I think (and hope) things will be changing

around, and maybe the real " junk scientists " will be found out.
