Overhearing that one way to go greener that I've seen in most "go-green" websites was to cut down on flying, use telecommunications(a.k.a. Skype) instead. But as an aviation lover, it's proving a hard time for me. I don't get to fly that often, but I still love to see the world from a bird's perspective. I care about having clean air, clean water too, and I've been adapting a lot of things that has really lowered my own carbon footprint by a lot. I walk a lot, take public transport, but as for flying is another story.
