@ShaulaEvans there are volunteer opportunities in my neighborhood to assist with community gardens. There's plenty of open spaces that are perfect for this. Fresh fruits, veggies, seeds are available for anyone. We have seed shares, and I have found that you can grow a good supply in small places like a balcony or a back yard by growing in totes and containers. I'm planning on building a little stand that can store the extras from our garden for anyone who wants to stop by and grab something. People sell eggs and veggies on stands out here on these kind of things. I think I might do a "tip if you'd like" thing and use that for improvements. It's working out for this neighborhood, and I think these are the kinds of things anyone who has the time could do.
I have no affiliation to this, but this is the organization called Giving Gardens: ://www.givinggardensforall.com
