All these things are great except one point in my opinion. I never understood "I won't have any children so I can minimize the effect on the climate". How about "I will have 2 children at max and teach them what I've learned so far but at younger stage? so that they will act responsibly in the future regarding climate issues while living and maybe doing things to lessen the climate change effects in the future?".

In the end, it is your choice with what you want to do. Things you're doing to contribute less like being car-free etc. are good, but I really find this extreme stance of "not having children for climate change" short-sighted.
