It’s not wrong to do any of those things, however systemic change would have a larger impact. I’d rather have stricter laws making it illegal to have factory farms and all beef be grass fed to better use the land to produce food rather than growing crops to feed them. That would be an efficient means of turning grasslands into food without exhausting the water supply. Yes there would be less beef, but this would be a net positive for the world if we did this.

Its not wrong to try do do these little things yourself.
