Canadians are failing to balance reasonable food consumption with sufficient and sustainable production.

The modern agricultural system is producing more and more food. Too much food. The cost is enormous: excess nutrients are contaminating the air and water; soil is being depleted; species loss is plunging us toward the sixth extinction; and farmers, racking up debt, are increasingly vulnerable to economic and climatic shifts.

At the same time, people are consuming too much food. Two-thirds of health-care costs in Canada can be attributed to chronic diseases associated with unhealthy eating. And then there is the waste - householders, food processors, distributors, wholesalers, and retailers collectively waste 40 percent of the food produced.

A radical rethink is required. We need to move from excess to enough.
