Eat local!

I've made this point before, but while Jon Schwarz is mentioning it, I'll say it again. Changing your eating habits is one of the easiest ways to really make a huge difference in the world. Think about how much money you spend per year on food, and imagine if that amount went into your local community to people growing food in an ethical way, rather than giving it to giant, evil corporations that abuse workers, animals, and the environment to increase profits for the wealthy people that own and manage them.
