I believe that eating local food grown in your town is a very good thing. It can help decrease the amount of harmful gasses that are being emitted into the air by the trucks that transport food. I don't have a garden, but many people from my church share with us a lot of fresh vegetables from their gardens. I think every one should start eating food that is grown in their own town, instead of food that is transported from places around the world.

This is an option viable only for villages and medium sized cities. How can you feed a city like New York only with local produces? You can't really do it. Also, those countries that are mainly producing food are going to have huge problems after a while. But, just for little cities, this isa brillant idea!

You are so right, it would be hard to feed a big city like New York with only food grown locally. We could start with the small cities and then slowly, somehow, start eating locally in the big cities.

It depends how you define local. NY is a big state with a lot of farms. It could feed more people in NYC than you might think! And then, what about vertical gardens (on the sides of buildings), and rooftop gardens? So many possibilities!
