Don't do it for the world. Do it for your own clear conscience. That way you can always say to yourself: At least I did my part (even though it's clear everyone can do more, but perfectionism doesn't help either. Personally I am content if my climate impact is better than 70-80% of my cohort.).
Also good for your overall mental health. Consumerism is a disease. Only way to beat the hedonic treadmill is to step off it.
