> Can't even change the small things, as we see through outrage over plastic straws still, nevermind trying to get people to eat less meat.
If you want people who aren't ideologically on board to sacrifice, you need viable alternatives. Cardboard straws suck ass. Without exception, every single cardboard straw I've ever used was soggy and tasted... well, like cardboard. They simply are not viable replacements. Fake meat is better at least (I've had impossible burger and it's legitimately good), but it's hella expensive and that's going to be a hard sell for people. Moreover, talk about not eating meat is absolutely dominated by people who have a moral objection to eating meat, not people who are concerned about carbon emissions. Which is fine, but the majority of people don't agree there is a moral issue (and many even think it's crazy to hold that position), so that's not going to convince anyone to bear a higher price. Get the price more on par with ground beef, get the public perception to be about the environment and not animal rights, and you could probably see big changes.
Conversely, look at LED bulbs versus incandescent. While they cost more up front, LED bulbs last forever and cost so much less in terms of electricity that they are just overwhelmingly better for most uses. I myself don't give two shits about the environment, but I don't see myself buying anything but LED bulbs ever again. They're just that much better. That's the kind of innovation one needs to advance if one wants to change the behavior of the masses. Give them something which is not only environmentally better but practically better, and they will adopt it. But you can't expect most people to sacrifice for the environment. The reality is that most people just don't care, and they aren't going to sacrifice for something they don't care about.
