We need to change ingrained cultural practices
Food waste is a $31-billion problem.
Every year, roughly 40 per cent of perfectly edible food that is grown and imported is thrown away. Of that, households account for half of the problem. Discarded food usually takes the form of unwanted leftovers, imperfect food deemed unsalable, oversupply, and, worst of all, supply management (throwing away food to keep prices high).
