The most talked about environmental issue is probably man-made global warming. The focus on this issue is so pronounced that it has led to mocking comparisons of Al Gore to a prophet and the destruction of the earth by global warming to the apocalypse.

The problem is that man-made global warming is simply not backed up by enough evidence to become the foremost environmental issue. In the face of record cold, doubt has even been expressed that global warming is occurring at all, let alone as a result of primarily human activity. Since the science simply is not there for man-made global warming, it should take a back seat to more pressing and tangible environmental issues (these issues will be noted in the section “Issues for Environmental Stewardship”).

Another serious problem with mainstream environmentalism is that it has become so politically charged that it is no longer dedicated to the issues alone. It seems that more time is spent arguing about global warming than actually doing anything about it (not that anything needs to be done about it). There is too much rhetoric and too much political opposition. This is partly because the environmentalists have for some reason made tenuous and controversial global warming their major issue. If the major issue were litter cleanup, no one could possibly disagree. But basic, important environmental activities such as litter cleanup are overlooked because of the political debates over controversial issues.
