PiT,
First, thanks for the honesty.
Not a problem.
Second, from my experience, most alledged believers in 'global warming' are merely using that as a pretext for larger and more intrusive government, with less freedom.
Hence why I view the extreme evironmentalists as dangerous. Not to mention carbon offsets are really useless anyway. They're just taking care of the Carbon Dioxide from smoke, without doing anything about the Carbon Monoxide or the Hydrocarbons.
Third, if you take a look at developments over the past couple of generations in the United States, you will see remarkable progress on water pollution (which is far more critical than air pollution).
Not to mention that since the late 1800s, huge progress has been made in all forms of pollution. Nevertheless, there is still progress to be made, & air pollution still exists. I would support some concessions to combat pollution, like signing the Kyoto Protocol.
Nevertheless, we shouldn't make it such a big priority that we tear down our economy to destroy all pollution. There will be more ways in the future to further reduce pollution.
