That said, I have personally stopped profligate purchases on Amazon/Express - promised the wife we'd clean out the garage before buying new non-essentials and have reduced online spending to 1/5th of last year (YMMV our garage was chock full of stuff).
If people were actually following the program, we would be in a much different place.
No need for that, some of consumers themselves have begun shaming their fellow consumers who buy way more stuff than they need. I know I've started doing that in the last couple of years, since I've realized that no amount of recycling or legislation is going to stop climate change, it has to start from us. Yeah, people who buy a lot of stuff are to blame, if you buy a lot of stuff you're to blame for all the bad things that happen to our climate.
