Guest guest Posted July 14, 2001 Report Share Posted July 14, 2001 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.
