Many of us agree that global climate change is real. Unfortunately there are still some disbelievers, particularly in the Republican congress. They could be our undoing and I don't think they know it. To those, it's crazy leftist hippie progressives celebrating Earth Day by wearing vegan shoes.
The thing, the really funny thing, is that all that doesn't matter. No one can disagree that our emmisions level have *an* effect on the environment. And that CO2 levels are higher than they once were. Much higher. So it cannot hurt to pass legislation to reduce emmission. Why fight so hard against it?
And working with the environment instead of fighting it is actually easier and cheaper. In the book Cradle to Cradle, Bill McDonough cites a nomadic tribe that lives in a hot, desert environment. They make their tents out of a hand woven dark yarn - I can't recall the details - which, to the civilized observer seems counter to logic and very exposed. But it's a fabric that is made in and developed for the environment. Turns out that the color keeps the interior cooler, and, when it rains the fibers expand and become nearly impervious. On the other end of the spectrum, we lived in an air conditioned house in the south that was clearly not built with the local environment in mind. The big windows were placed so they took sun nearly all day and in the summer the HVAC couldn't keep the house below 85 degrees.
I guess my message is to work with your local environment, not against it, and to pick your battles. Environmentalism is easy and, whether you've realized that global climate change is real or not, it's a good thing to do. If the consequences may be the demise of civilization as we know it, don't you think it's a good idea to go for it? You know, just in case?
