Expanding weatherization assistance for low-income families was one of the the issues I worked most passionately on during my time in the world of environmental advocacy. After you’ve talked with folks who must regularly figure out whether to pay for medicine/groceries/etc that month or keep the heat/cooling on, there’s no other way you can work these issues.
Everyone thinks of a bunch of granola-eating hippies when they hear “environmentalism.” I think of these families, and a world where they and future generations all have the same opportunity for the pursuit of happiness that most of us take for granted today.
