Does the US debt threaten to end the life on earth? Then I'll happily join the movement that aims to bring it down by private action. I know individual action on it's own is not terribly effective. The game plan I see here is that we keep public focus on how bad meat eating is for the environment, and hopefully reach a critical mass in public opinion so that one day it is politically acceptable to reduce the dairy industry subsidies. It takes time, but it is a feasible idea.
