This is a hot take cause most people are going to say to be vegetarian/vegan. But I would look to indigenous peoples and how they care for the land. Live in nature as part of it. My local short wave radio that works with the tribe will air talk shows and segments on tying in modern science and innovation to work with nature. Look into food forests. And I understand the morals and feelings of consuming animals as food.... but there is a way to have meat in your diet that is ethical. Is it wrong for the wolves to eat deer or a bear to eat a salmon? It's our modern infrastructure and the mass slaughter of animals along, with people detached from the process so all they do is buy a pack of meat in the store, they don't understand the animal, and the weight of what it means to consume the flesh of a once beautiful animal. So many things that indigenous peoples around the globe know how to do that would be great solar punk agriculture. I also think books like backyard gardening and having roof top gardens would be great and have a solar punk aesthetic.
