Maybe this has been done already and its suppressed by capitalists. But, people should really think outside the box for solutions to all of our societies problems and come up with a sustainable way of living with nature. I'm thinking stuff like sustainable agriculture, waste, recycling, energy consumption, urban planning, and how these could all fit together to work. I guess its "utopianism", but is there a way for humans to co-exist on Earth without slowly killing it? Do we need to look to the ways indigenous people live? Or is there something in between here and there that could work?
