We appear to be developing another drought and Dust Bowl problem in the same areas that it hit before. Such a coincidence.
But back to the original question...
Letting food be controlled by big business and government shouldn't be allowed by the people. The people themselves need to relearn how to grow food, but there is a fairly steep learning curve. Grow food, trade food.
If you and your neighbors can grow food of open-pollinated types, save the seed and regrow even more food, food can be multiplied. This is the way it has always been, and will always be. There are no shortcuts, no easier ways, no matter what you're told by others who have their own private agenda.
