Pollution Footprint

Why is it that the people of today don't seem to care about Global Warming or the environment? All anyone seems to want to do is make tons of money so they can live the P. Diddy lifestyle. How does that change, how do the people of today reduce there "pollution footprint"? I can't sit here typing and say that I am the epitome of a go greener, what I can say is that my car gets above 25 mpg in the city and on the highway, I recycle everything that can be including my grocery bags. I purposely moved to a central area so that I could spend my weekends walking to all the things that I want/need to do. It is my hope that these little things help in some way, and though I can't afford to buy a hybrid my next car will be a manual, two door, 4 cylinder, because as much as I love to speed, I like the view out the window even more.
