I think that home grown foods can be very helpful when it comes to our climate problem. Growing your own produce guarantees you that its organic and non-GMO. Most people probably don't have good soil for growing produce, and would probably turn to fertilizers. There's nothing wrong with fertilizers, as long as they're organic. We have a garden at my house, and so do all of my neighbors. Even if it starts out as an effort to help with climate issues, it becomes into a hobby.
