In a bit more detail:
How about less cars? More effective public transit is good for people and the climate.
Let's do away with golf lawns and pools for every house... Perhaps architecture can be adapted to suit the specific location instead of stamping the same stock photo "American house with garage that can fit 4 cars." Look at passive cooling and stuff. [Again, I'm talking about redefining comfort. Is a personal pool and large car and trimmed lawn really, honestly, what makes you comfortable? Or is it more a product of culture and advertising? You're absolutely free to believe either way, and I don't want anyone to force you to do anything.]
And honestly, we need to consoom less. Devices should not have a lifecycle of one year. You and I don't really need all these gadgets and trinkets, either. Let's stop buying random things
If you think this is a distraction or that it won't work because we can't get everyone to agree: Degrowth and permaculture requires honestly no critical mass. You can choose to buy things that last longer, and use them a bit more. Learn to fix things, etc. These are all nothing but straight benefits to you (more money in your pocket, skills that can make you more valuable in the current system, more time available now that you aren't swiping short form videos all day).
