Increased stress on the environment

Approximately 7 percent of planted fields in the United States are typically not harvested at all each year! U.S. food waste represents 4 per cent of all US energy use and approximately a quarter of all water use >>

Increasing standards of living and the booming developing economies have also changed the types of food consumed with an emphasis on a projected growth of meat consumption. One hectare of land can, for example, produce rice or potatoes for ~20 people per annum. The same area will produce enough lamb or beef for only one or two people where beef uses up-to 50 times more water than vegetables. The core of the challenge is found in the fact that in terms of land-use, agricultural food production based on livestock is far less efficient than that based on crops. For example, depending on climate, variety, agricultural practices, length of the growing season and degree of onward processing, between 500 and 4,000 liters of water are required to produce 1kg of wheat. In contrast, to produce 1kg of meat requires between 5,000 and 20,000 liters of water.
Bottom line food waste and shifting trends in food consumption in developed societies and fast developing nations are creating an ever-increasing burden on natural resources and the environment.
