　　Ⅱ.阅读理解

　　Worldwide, at least one-third of all food produced is wasted every year. With an extra two billion mouths to feed by 2050 global food waste is an escalating

　　issue that is difficult to ignore.

　　We throw away or waste 1.3 billion tons a year at a cost of $1 trillion, according to the Food and Agriculture Organization of the United Nations (FAO).

　　In industrialized nations, almost half of the food spoiled — roughly 300 million tons yearly — is still fit for consumption. This is more than the total food production of sub-Saharan Africa, and enough to feed the estimated 870 million people currently hungry in the world today.

　　The FAO set up a Think. Eat. Save campaign in January 2017 to try to change the way we view food. In partnership with the United Nations Environment Programme (UNEP), they are trying to reduce food loss along the entire chain — from farm to fork, boost awareness both at a household level and at a national level, and help both individuals and organizations to reduce food waste.

　　?This is a complex issue,” said Nick Nuttall, a UNEP spokesperson. “If you do not measure or monitor it, you can’t manage it.

　　As travelers become more aware of the challenge and impact of food waste, increasing numbers are likely to choose hotels and restaurants with policies and programmes in place.”
