I find it very interesting how the image of a large, powerful (and absolutely sweet!!) machine generates such rhetoric about the environment and of course - Global Warming. I am happy to see though that we still have some intelligent ones out there that can appreciate the beauty of this machine and eloquently point out that big is not automatically equated with bad and evil. I was going to resist getting sucked in to the political garble but what the hey. I think it is so cute that a collective group of so called advanced mammals are so arrogant as to think that they can bring about mass climate changes. One massive volcano can release more greenhouse gases into the atmosphere than years and years of industrial development. Let's sit back and think about this. The earth has experienced extreme climate changes and multiple mass extinctions cross millions of years - guess what - without humans!! She has come in and out of an ice age without - guess what - right without humans. As a species we will continue to evolve as well as the planet and at some point as has happened for millions of years the next major geological period will be defined with a major geoligical event and mass extinction. Folks start thinking for yourselves and stop worshiping this washed up political dope, flinging himself around the world in his "fancy flying carbon footprint" machine. Taking care of the environment is the right thing to do but an individuals choice. We should each acknowledge that we are a highly consuming mammal and should continue to find ways to improve how we consume. Understanding your carbon footprint is one way of accomplishing that. Take care of the planet because you live here and are a consumer of it not because some puesdo-scientific political movement twists data into blaming you for something that would have happened anyway.
