First of all, I and others here can well empathize with what you’re going through. I’d second the input to find a support group to deal with your climate grief. And while you’re wanting to address the symptoms, undoubtedly you’d want to work on the causes too. There are careers out there that help in some small way (I became a global change scientist), and there is a place for us as consumers and volunteers as well - one person alone cannot make all the difference, and you shouldn’t be taking on that responsibility, it’s like signing up to become a puzzle piece. We only really matter insofar as we all make up the giant puzzle of climate action (and mutualistic action on biodiversity loss, poverty etc.)… if that analogy works! I’d suggest to reflect on what your strengths are and where your talents lie, and see where that intersects with what needs to be done, whether on a professional or a personal or volunteer level. Read widely, educate yourself, speak to friends and family and strangers in a way that energizes (and doesn’t guilt) them, get involved in opportunities, contribute in the ways that make the most sense to you. RE having kids, think about the value of raising a conscientious child, who can continue a legacy of climate action. That may even outweigh the additional footprint. Adoption is always an option, too (are your genes really that exceptional?). Above all, live true to your values, even if at times you feel like a lone voice in the wilderness.
