Major environmental changes have taken place in less than a lifetime. Seriously polluted waterways have been restored to their natural state. A hole in the ozone layer over Antarctica is shrinking and acid rain has been reduced. Birds of prey have returned to area where they weren't seen since the 1950s.Some other environmental changes have shown serious deterioration in our environment. Plastic waste is becoming ubiquitous. Herbicides and pesticides are being overuses resulting in illnesses in both humans and animals. In the midst of all these changes, America's political environment has also been going though changes. It seems as though conservative politicians are being cast in a bad light when it comes to environmental affairs. In Saving the Planet; A Conservatives Guide, Robert Cote points out that some of the leading environmental advocates in American history were conservative politicians - from Lincoln to George H.W. Bush. He also presents plain arguments as to why there is no conflict between being a conservative and being a conservationist.
