CSA is structured to eliminate usury and waste, share risk in human cooperation, and pave the road to a better future. It is to learn the benefit of community and the abundance of nature. It replaces price gauging with fair play for both consumers and farmers in an environment of trust and social friendship.
Every person who joins a CSA --provided it is in arrangement directly with farmers -- helps a farmer detach from the predatory market forces that discourage localization and diversification needed to stabilize the food economy, build soil capacity, end pesticide contamination, ensure proper food safety regulations, reduce farm debt, and increase the number of young farmers. In other words, save farms that some say are being lost at the rate of 40 acres every hour in the US.
