Consider the following taken from the :http://www.fws.gov/endangered/esa.html
Whenever any species is listed as a threatened species...the Secretary shall issue such regulations as he deems necessary and advisable to provide for the conservation of such species.
Now keep that in mind while you http://www.msnbc.msn.com/id/11233316/ (from AP):
In a move hailed by environmentalists, the Bush administration announced it will review whether polar bears should be considered a threatened species given indicators that their icy habitats are melting away due to global warming.
Could the ESA really be used as backdoor legislation for global warming? Just wondering.
