My argument for that is: Why not create urban farms that are like parks, on public land? There actually is a park that I see as a model: Dover Street Park in Oakland. They took this park that has swings and playground-type things and turned it into a farm. There's not chickens, just annual vegetables interspersed with fruit trees. And it's super cool because you see people playing with their kids and then they go pick raspberries and some greens for dinner.

I don't think people are like, "I'm going to save the planet by planting my own herbs." But on environmental issues like climate change, there's a sense of hopelessness and despair. Maybe it's really a small gesture but if you can have a garden it may make you feel like you're helping in some way, or that you're making a connection. You can't change the world but you can change your backyard.

As cities get more dense, you have people saying, "Why would you have an urban farm when you could have affordable housing on that property instead?" So there's an argument against it. Another huge thing is there's a brain drain toward growing marijuana. You know, if someone has a green thumb in an urban area, especially in places like Washington or Oregon where it's now totally legal, why wouldn't you just grow pot?

I don't know Hillary's Clinton stance on urban farming. I don't know Donald Trump's stance or Bernie Sanders's for that matter. But the Obamas have been amazing. You know, Michelle Obama, she planted that garden. She keeps bees there at the White House. Little known fact, though, is that Laura Bush also had an organic garden but she never told anyone about it.

Even if you live in New York City, you can have a little basil plant in your window, and that could be considered urban farming.

There is this really intimate connection that people have with the animals they're going to eat. A lot of people who eat meat say "I would never kill my own animals." Well, that means someone else is doing it for you, ultimately. This is the modern attitude that we have: Somebody else will do that for me. And to me, it just seemed wrong. I wanted to be part of the process of what it meant to eat meat. I wanted to be responsible.
