I grow my own food and meat. I think growing your own food is the single biggest way to reduce your impact on Earth. All that industrial farming and transportation required to feed people. So many people living in single family homes could turn their lawns into gardens and produce _surplus_ vegetables. Several times what their family can eat.

And even people in dense urban areas could have community gardens ie rooftop gardens.

It seems popular to want solutions that doesn't involve any sweat equity. Which I find unfortunate, at best.
