A new report from the United Nation's Food and Agriculture Organization points to a major global food waste problem that's hurting the economy and the planet.
According to the report, one-third of the food produced each year -- 1.3 billion tonnes -- is wasted. The U.N. estimates that the waste adds up to more than $750 billion in direct economic costs annually -- more than the GDP of Switzerland, the world's 20th largest economy in terms of GDP.
In addition to economic costs, the report says that 3.3 billion tonnes of greenhouse gases enter the atmosphere from the production of uneaten food, making it a larger source of carbon emissions than most countries except China and the United States.
But which regional commodities are the biggest contributors? As Lily Kuo points out at Quartz, it's cereals from Asia, with rice accounting for the majority of the waste -- about 150 million tonnes.
Why does all this rice go to waste? Poor processing, transportation or storage result in rice being spilled or spoiled before getting to consumers. Some waste also happens on the consumer side as people simply throw uneaten rice away. The UN estimates that 80 kilograms of cereals, mostly rice, are wasted per person in the region every year.
