On Earth Day, we are not trying to "save the Earth."  It's not like it going to explode Krypton style.  We are trying keep ourselves from extinction.  To quote George Carlin, "the earth isn't going anywhere.  We are.  Pack your shit, folks."

So, how are we doing this?  Well, I have a very simple theory based on my knowledge of basic scientific principles...

a.) Trees (and other green plants) take in Carbon Dioxide and give off Oxygen.
b) Animals (including humans) take in Oxygen and give off Carbon Dioxide.

This seems like a nice neat co-existance... however, as we cut down more and more trees for new shopping centers and high-priced housing, that leaves less trees to take in the Carbon Dioxide that we give off.  This will, in time, most certainly increase the Carbon Dioxide in the atmosphere and decrease the Oxygen in the atmosphere.  Since animals and human need Oxygen to sustain life, we will only suffocate ourselves.  Man only will have himself to blame when the Earth loses it's ability to sustain animal life.  But, the Earth will remain, beit lifeless, but really isn't going anywhere... we are.  Pack your shit, folks.  Have a pleasant day.

Does this make sense to anybody but myself?
