This adminstration is no worse than Clintons in environmental matters. They both have strong points and weak points.
Clinton raised the CAFE mileage standard for cars but ignored trucks and SUV's. Bush ignored cars and raised the standard for SUV's.
Clinton ignored arsenic in drinking water for his entire term and signed an executive order to reduce the allowable maximum on his way out the door. Bush actually is implementing the standard.
Clinton had an all or nothing approach regarding air scrubber systems in power plants. If you weren't going to upgrade it all the way, you were not allowed to upgrade it at all. Bush loosened this standard and power plants have actually been spending money for equipment to upgrade. There is a mini boom going on for this type of environmental equipment.
There is a ton more like this. All administrations have a very mixed records on environmental issues.
I am not yet convinced that global warming due to mans production of CO2 is something to worry about. I think it is more of a distraction from the real environmental problems we have.
