Check out A Half-Built Garden by Ruthanna Emrys. A bunch of US citizens get so fed-up with the looming collapse of the planet, they form a bunch of socialist collectives who rely on the internet to function. It’s like a cross between reddit and Next Door. Problems are discussed, solutions proposed and voted on, information readily shared. These communities just focus on taking the best care they can of their own people and their corner of the world. Also there are aliens.
