These things only work if everyone does them. If we want people to give up their cars we need massive investment in electrified public transit. Without that it is impossible for most people to survive without cars. A few people who have the freedom and the will to suffer under public transit choosing to give up their cars will do nothing to stop climate change.
> You twist it around to pin the blame on green activists somehow not doing enough in their personal lives
Do we all have to do them.or not? That seems pretty simple. Yes, if you want everyone in the world to give up eg cake, then you need to start first. Otherwise you are virtue signaling - indicating group membership by taking no cost actions like wearing a pin, changing your facebook icon or commenting asserting others are not doing enough.
I too can tell other people to not drive or not eat meat. I don't because I still drive and I still eat meat.
> If we want people to give up their cars we need..
Now you are changing the problem.
As for renewables, I've bought shares in green energy in my pension and some in this scheme which allows people to co-own wind turbines:
When I buy my own home, I'll be installing an air source heat pump and solar panels.
As for flying, I've done it a few times but less than half a dozen flights in total in my life. My plan is to interrail one day.
So yes, actually I have more or less done what you suggested. It takes time and commitment, and the centre of my argument is that making the choices I have made should be easier than making the choices that contribute to climate change. Down vote all you like.
