so yes, I do care about the environment. Air travel is something that concerns me, but of all the contributors to green-house gasses it is one of the ones that I see hardest to change/decrease. Case in point - I come from London but live in San Francisco and there is no other (reasonable) way to travel between the two cities other than by air. I don't get how my argument is like voting. If we all vote together then something positive happens (change). If we all 'vote' by not flying then the airline industry collapses - which is not positive. If I've miss-understood your example + argument please elaborate.
