　　Why Do People Waste So Much Food?

　　Up to half of the food the world produces is nevereaten. It is instead thrown away. Experts say food iswasted in both rich and poor countries, but fordifferent reasons.

　　Elliot Woolley teaches about sustainablemanufacturing at Loughborough University in Britain. He spoke at the Global Conference onSustainable Manufacturing, held earlier this month in Vietnam.

　　Mr. Woolley says in poor countries, food is usually lost while it is still in the field or duringstorage and transportation. He says that is because food producers there are inefficient.These businesses are unable to operate effectively without wasting materials, time or energy.But he adds that once food is sold in developing countries, people usually eat everything theybuy.

　　However, people in the United States and other developed countries throw away as much ashalf of the food they purchase. The British researcher called this custom "a disgrace."

　　Elliot Woolley has created a smartphone app that he says shows users what food they havebought and when the food is about to become unsafe to eat. It also gives information on howpeople can combine the foods they have to make a meal. The software program is called the"Pantry App."

　　Mr. Woolley said that people who used the app reduced the amount of food they wasted by athird. But this result came from a limited experiment -- users only followed their food use for aweek.

　　Jeremy Bonvoisin is a student at the Technical University of Berlin. He attended the recentconference in Vietnam. He said one way to solve the problem of wasted food is to take stepsto persuade people to stop buying so much food in the first place. He said people buy morefood than they need because it is becoming less costly. They waste so much food because theybought more than they needed.

　　He says the new app could help those who already want to change the way they use the foodthey buy. But he is also worried that it could get people to waste more food because they nolonger have to pay attention to how much they have bought.
