Cost of food as catalyst for change cannot be ignored

Aca "One of the elements often overlooked is the heavy reliance on both energy and water in the production and availability of food. Food production is largely agriculture – which requires land, energy, water, and chemicals for fertilizer. Food availability, on the other hand, encompasses ports and shipping, rail systems, trucking, refrigeration, warehousing, storage, supermarkets, packaging (more chemicals), transporting consumers to and from markets, home refrigeration and, particularly in developed countries, a huge amount of waste disposal. The movement of food from farm to market to shopper is a major consumer of energy but those energy costs are not captured in the price of the food on our shelves. As we run out of arable land this will change, prices will rise and cities must become part of the solution."
