Climate change and the increased occurrence of extreme weather events are beginning to threaten our food supplies more and more. Together with the delicately balanced re-stocking of supermarkets, the margin for error is large. The ease of use of supermarkets lulls customers into a false sense of security, there is little alternative capacity to provide food if supermarkets fail.

Supply chains should shrink and begin to relate directly to local markets again. Supermarkets have too much control over food supply and too often food is grown locally, sent to a central depot and then distributed back to its origin.
