We could debate this until the cows come home, and we won't solve anything. So, let me point out something.
If we, as a society, decide to change our way of life to do something about global warming, and then it turns out that we were wrong, what will be the problem? It will have cost us money and time. We will have given up some of the things that bring us joy(gas burning, tire screeching, wind in your face joy), and in the process will have made a cleaner world.
On the other hand, if we decide to do nothing, and we end up being wrong, the consequences could be much worse.
We as motorcyclists are inherently risk takers. We take risks, but only for ourselves. Should we be willing to take a risk for the rest of the world?
