I don't own a car, I don't eat meat, I consume very little and try to buy used things instead, I repair all my things as much as possible, I try to steer my investments away from anything close to fossil fuels.
Now you.
We have to accommodate these lifestyles (and build tech to make it more sustainable) - people generally don't want to go 'backwards', even if you or I don't perceive that as a problem.
Ultimately it's irrelevant, because both of our lifestyles are still heavily carbon negative without offsets. We both own a computer or live in a house I assume? That's why I'm sceptical of the "just live more sustainable" movement.
