around the world, about 1.3 billion tonnes of food are discarded each year, accounts for One-third of our total crop. So the waste is caused? In poor countries, most food waste occurs on farms or on the way to markets. In South Asia, for example, there is a loss of half the cauliflower grown because there is not enough refrigeration facilities. If used in large bags, tomatoes will be crushed; in South-East Asia, lettuce will rot on the way from farms to supermarkets in the city, and in poor countries, where consumers throw away only a handful of food, they are too precious. But in rich countries, especially in the United States and Canada, 40% of food waste is due to the abandonment of consumers. The nation wastes more than 160 billion dollars a year.
