Consider the formation of capital. We get new capital - new wealth - from the natural environment. There are 4 main sources: fossil fuel, timber, ore and farming. The first 3 are extractive and unsustainable. The fourth - farming - is now extractive and unsustainable for the most part because of poor farming practices. However, it doesn't have to be that way.
If you grow food, you have capital you can use to your advantage. You can sell it, you can sell it to some and not to others, you can give it away, you can give it away to people who are doing the same thing you are, and you can use it as a teaching tool. As a producer of food, you automatically have a higher profile for whatever politics in which you engage.
Since we are in the early stages of not only US collapse, not only European and not only Asian collapse, but very likely collapse of a civilization built on cheap energy; it is to your advantage to get involved in the food production process and try to do something useful. None of us can prevent collapse, but we can mitigate the consequences. It will be easier for the people around you if you have a lot of food to share.
