Guerilla gardening.
Seed bomb.
How does one start guerilla gardening without growing poisonous food because of the soil? Well stay tuned because I'm going to find out.
I don't think governments will have the money to feed increasing numbers of people who will be out of work, money and food. Food banks likely won't be able to keep us all fed. And I don't see corporations as having a heart so they won't be feeding the masses. We'll have to feed ourselves and not all of us have yards for gardens.
Guerilla gardening -- do it wisely.
