Well, I also see a lot of people who do the tiny thing but not the big thing. Plenty of people around me are reducing their meat intake (and are vocal about it), because climate change, but still fly on airplanes, some multiple times a year. It's so incredibly frustrating that many people are just green washing their lives, but are oblivious to the fact they're not really doing much at all.
I do have massive respect for the people I do know that have quit eating meat and are now doing all their travels by train.
