I agree, but find it unlikely that a change will happen top-down either, as the politicians and corporations are even more corrupted than individuals.

I ride a bicycle too and don't own a car. I buy stuff second hand etc.

I do fly but only because it's pretty much the only way I can get to my family across the world. I do this about once a year and spend a few months there whenever I go.

So this is exactly what has been on my mind of late: why bother compromising your own quality of life at all, if it won't make any real difference?
