"We're talking about should we increase taxes? Why not put a tax on carbon emissions. It would raise a lot of money, it would reduce the environmental damages in the future, it would solve so many problems, and it would be a much more constructive thing to do than to think about raising the income tax."

My wife and I have purchased two hybrids. We bought a 3 kw photovoltaic unit. We recycle and offset our carbon emissions on the Internet. We turn things off. But we also spend two nice salaries every year, and here's the dirty little secret - our environmental footprint is HUGE, I'm sure. We've all got to do what we can in our individual lives, but we've also got to drive the systemic changes that will make the big differences.
