I do and I try. Buying beans instead of meat and oat milk for udder milk is a really easy thing to do on a personal level, if you look at the damage you avoid by doing so. Some things can be changed easily, some take efford, some can not be changed at all on a personal level. Buying second hand stuff is rather easy for me as well. Giving up on my car would take much more efford, I'm not ready yet. Getting out of the firm grip of all fossil destroyers is nearly impossible. So, let's start easy when you shop for groceries next time. :)
