AlQa'dah 5, 1434, Sep 11, 2013, SPA -- Hundreds of billions of dollars are lost and billions of tones of greenhouse gases are needlessly produced each year due to food being wasted, the United Nations' Food and Agriculture Organization (FAO) said in a report Wednesday. In developing countries, food gets lost because of inefficient harvesting or poor storage conditions, while in richer nations edible fruit and vegetables are thrown away because of an unusual shape or color, or food ends in the bin due to over-buying, according to dpa. "Each year, food that is produced but not eaten guzzles up a volume of water equivalent to the annual flow of Russia's Volga River and is responsible for adding 3.3 billion tones of greenhouse gases to the planet's atmosphere," FAO said.
