1 . Across the globe, we've developed a coffee addiction, and we've become addicted to single-use cups: 600 billion disposable cups are produced and sold annually. But there's a growing push to cut this down.

Here's the problem with disposable coffee cups: The thin, waxy, plastic coating inside makes it tricky to recycle or compost them. So, they most go into a landfill （垃圾填埋场）. More than that, it takes a lot of energy and resources to make them. Starbucks and McDonald's are trying to develop a disposable coffee cup that can be both recyclable and compostable. But that's easier said than done. The coffee giants have been dangling a million dollars to anybody who can crack the code.

The Rolling Stones are also thinking about the sustainable cups. If you see the Stones in concert this summer and go to get a drink, there may be no single-use plastic cup for you. The bands approached Michael Martin, who has produced a bunch of big Earth Day concerts, asking for help to eliminate plastic waste. He came up with a simple solution.

"When you come up to get your first beverage（饮料）, you put down a $3 deposit, you get a really high-quality Rolling Stones-branded cup," says Martin. "You use it throughout the night, and at the end of the event you can turn your cup in and get your $3 back or you can keep your cup." If you return the heavier plastic cup at the end of the show, it gets washed and used again. Or recycled.

But this idea — returning and reusing a cup — this is not that complicated. So why is this just being tried now? "That's a really good question," says Martin. "In America, we're a throwaway society, and so we're hoping we'll be able to wake people up and change things." He's starting with rock concerts because artists have a pretty powerful platform. I mean, if Mick Jagger tells his fans to stop abusing the planet, who's going to say no to that?
