We can’t just get out of capitalism, but you can work to improve your situation. If you have a yard, grow a garden.
Also, see if there’s a mutual aid group in your area, and if not consider talking with your neighbors about what you can do to help each other out. One person might be good with car Maintanance. Another might be a good gardener. Everyone can contribute something.
Gardening will not solve the climate crisis because it won’t offset the millions of tons of co2 being emitted.
It would help, sure, but we have to radically change production to stop it. Currently the rich own those, so the best we can do short of removing them is plead.
Also yes, you can’t just get rid of capitalism, history shows it takes years/decades of planning and organizing. Start as soon as possible because I don’t think we have all that much time.
Where did I say it would solve the climate crisis? I was just having an alternative to capitalism to provide some of your food. Of course it won’t dismantle capitalism or save the world. People have been gardening forever, yet here we are. It’s just a step you can take to take some control over your situation back.
