My land is a regular suburban
yard about 15 minutes north of Disneyland. I've planted about 60 fruit and nut trees, and grow about 75% of the veggies that we eat. We keep 8
chickens, which is more eggs than our household can eat, so my wife sells a dozen or so every week to co-workers that are excited at the chance to but them for $6 a dozen. We keep
bees, capture our rainwater, and keep hundreds of yards of
wood chips from going to a dump by putting them down throughout the orchard. What started as a small garden has evolved into a significant shift in our lifestyle.
There is land all over. My next door neighbor has given me access to grow anything I want over in her yard. I don't have time to maintain more than my yard, but her space is even larger than mine. All it takes is a bit of initiative and a willingness to ask people, "Would you allow me to grow stuff on your unused space?" You've got to be willing to go against the suburban norm, but if you're willing to do so, rather than wasting water on grass, we can grow a lot of food, sequester a lot of
carbon, and significantly increase the tree
canopy.
