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.
