Why should the average person reduce his/her life quality in order to save the climate, when the average billionaire emits as much CO2 as one million people from the bottom 90% of the population combined? I do care about the climate, but it's clearly irrational to make sacrifices, when other people are unwilling to do that. Having a higher quality of life is more valuable to me than the tap on the shoulder I can give myself for playing my part in living responsibly.
