It will end when you and me decide to stop it. Simple.
People can do something to block it and actually it's easier than you may think. Native people in Canada have been doing railroad blockades for a long time, and in many cases it did have a significant impact in TPTB's politics.
All you need is some committed friends and neighbors, you make a call out for a blockade through everyone's social networks (though avoid Facebook at all costs, as it will lead people to being prosecuted and jailed!) without saying where it is, then you do it and send the invitation and location to everybody, while some people post it on blogs and news sites like this one, and a Twitter page should help. Bring a lot of stuff to survive there for a while, food, tea/coffee, tents & warm clothing/sleeping bags, anything and tell people what they could bring as well. Have a few legal contacts who know enough about "activism" cases, and also a few people with street medic training and equipment. It's gonna be a much greater and lively experience than sitting in a cubicle to watch the horror show happen, I promise.
