1 . Did you buy too much bread before heading out for a holiday? Did you give up the vegetables that are going bad?

In an effort to help eco-conscious consumers, a Geneva nonprofit is speeding up its plan of street-side, free-access public refrigerators that restaurateurs, at-home cooks and others can use to give away food that’s about to go bad. It’s part of a bigger effort by communities in Switzerland and other European countries to do their part for the environment while helping to cut down on food waste.

The nonprofit Free-Go has placed refrigerators and shelves in Geneva where passersby can get fruit, vegetables, bread and other perishables(易变质食品) to take home for free.The program costs about $40,000 to run each year and enjoys the support from the city government. It began a year ago with a single fridge outside a community center in western Geneva and it now has four fridges, strategically placed around town. A fifth one is planned before year’s end.

Free-Go is experimenting with scheduled pickups at apartment buildings to make it easier for residents(居民) to participate in the program. It has also set up a“hotline”that restaurateurs can use to call for the collection of unused food. Free-Go says giver s of food from the private sector, such as restaurants, must make a promise to ensure the given food is safe to eat.

Free-Go says about 1 billion tons of food go to waste every year around the world—using up energy and other resources in the farming and transportation process. Similar food-sharing activities are in place in the capital, Bern, after the idea was imported from Germany.

According to Foodsharing.de, a community group in Germany that started more than a decade ago, more than a half-million people in Germany, Switzerland and Austria have made “the food-sharing initiative an international movement”and have helped save 83 million tons of food from going to waste.

Over and over at the UN climate summit in Glasgow, world leaders have stressed the need     1     (limit) global warming to 1. 5 degrees Celsius. Experts have said crossing the 1. 5 ℃threshold(界限）risks     2     （release) far more severe climate change effects on people, wildlife and ecosystems. Preventing it     3     (require) almost halving global CO₂ emissions(排放) by 2030 from 2010 levels and cutting them to net-zero by 2050.

Already, the world has heated to around 1. 1℃ above pre-industrial levels. Each of the last four decades was     4     (hot) than any decade since 1850. “We never had such a global warming in only a few decades,” said climate     5     (science) Daniela Jacob at the Climate Service Center Germany.

“At 1. 5 ℃, there’s     8     good chance that we can keep most of the Greenland and west Antarctic ice sheet     9     collapsing,” said climate expert Michael Mann at Pennsylvania State University. That would help limit sea level rise to a few     10     (foot) by the end of the century.
