I have in fact been eating tofu my whole life, because I grew up vegan. I am also a member of the largest union in my country. I am a bicycle rider for several decades now and can proudly tell you that I never owned a car. On top of that I have been vegetarian and did not fly during almost my whole adult life, etc. However, meanwhile the industry kept polluting and things went worse and worse, independently of my individual behaviour. Individual lifestyle choices are not enough, we have to act and end the fossil industry fast or they will doom us.
