My husband and I don't have kids, and we've severely cut back (not fully cut out yet), but really cut back on our meat consumption. I also avoid buying plastic whenever possible, and buy things like toilet paper/paper towels/regular linens made from recycled materials. Actually, if I have the option to buy anything made from recycled materials I'll typically opt for that. That's about it right now.

Only tangentially related to your question, but I'm also in a Master degree program for Public Administration so when I retire from the military I can roll right into law school. My goal is to become a Public Defender, which, I know, is fucking hard work with a lot of burn out for little pay, but I do have confidence that I can be an extra pair of hands for an overburdened industry. Everyone in the US is entitled to competent representation, and I've no interest in representing those who can afford their own lawyers.

And it burns me up that the rich can often get away with paying simple fines while the poor who can't afford it go to jail and become essentially legalized slave labor. Fuck that. Anyone I can help save from losing their livelihood, home, family, car, etc, is a big fucking W in my book.
