What exactly are they protesting? The issue with the pipeline is not only the technical issues but the tactics of the corporations. The real issue was the integrity of the political process. There was collusion between high government officials and the industry to get this through before the public had a chance to be heard. They stopped it and they also gave the President the ammunition to fight the right battles. He couldn’t have done it without the people power.
That is why the Occupy Wall Street Protestors are so important right now to build the support for change. It is almost a boycott of these companies to make them wake up that people really do have powers in numbers. You do not necessarily have to sit down in a dirty street and get hit over the head by some cop and be dragged off to be arrested for basically harming no one. By organizing web sites geared to a cause that you believe in, by being a member of that organization you can be heard and your views will be acknowledged. Yes the good old fashioned petition.
