Right but you have to begin somewhere, and being a good example for others certainly helps as well.

I try to change my life such that it doesn’t impact me much while having fairly large effect. For instance I’m basically vegan (still eat meat occasionally, e.g. when it’s otherwise thrown away), I even don’t want to eat meat anymore, the taste just got worse for me over time.

It also has effects on the market, e.g. Meat replacement products are quite affordable and popular.
