Everyone. I am very aware of that. But you can’t expect the whole world to just change from the individual up - it isn’t realistic, because the current state of our civilization requires it. Going around making people feel guilty about using a gas powered car is not helping anything, if anything it hurts the movement because we could come off as assholes, and then no one listens us. People have to like you if you are going to convince anyone of anything.
The only real, substantial thing we can do is get people to elect progressives at this point. That or start disrupting the actions of these companies in any way possible. Telling my parents not to go on vacation though? They’ll think I’ve been brainwashed by AOC and go even further into their trench.
For the record though, I’m not trying to be angry - kudos to you for being conscientious of your impact on the environment and your passion for getting the word out about it.
