How do you feel about urban farming? I think it's a great way to get kids (and anyone else) involved in their community, provide some nature in a city environment, and also provide some responsibility and pride in your actions. Plus you're helping to provide for yourself! I also think urban beekeeping falls under the same categories, but perhaps with a bit more responsibility involved, since you are dealing with animals that are potentially dangerous.

Also, read about urban beekeeping, since I sort of randomly brought that up.
