Supermarkets are the biggest threat to the environment. They stop people having real choice over foods, they sometimes deliver only a few items in their trucks, the safety record of these trucks is awful, they are the largest seller of processed junk foods, they are responsible for half of landfill and they are the largest provider of disposable goods including plastic bags which take 4,000 years to degrade. Tesco is one such operator that is trying to kill off connections to locality and food.
