@ryo @lolicon @roboneko @ArdainianRight @antisophon @x0x7 American suburbs are a different story. But depending on state/local laws you are limited to what you can grow in your backyard. You can raise animals in some places. Rabbits seem to be a popular animal to raise for food, but there is huge controversy around it because they are also a popular pet.
And lucky for me, my parents told me that I'm always welcome to use their backyard to grow anything even after I move out (which still hasn't happened), though they're not comfortable with raising animals.
