For the first time ever, the Winter Olympic games will rely entirely on artificial snow.  It’s a reality that could become more common as the planet warms. And it has environmental experts concerned.  Nearly 50 million gallons of water are being piped in to serve the Beijing games, possibly setting reserves in this water-stressed region back by hundreds of years. Meanwhile, China says this year's event is the most environmentally-sound winter games ever. But there's no system to track those claims – and some researchers say the Olympic games are actually getting worse for the environment over time. This week on The Carbon Copy: why claims about the sustainability of the Olympics are often greenwashing.  Guest: Christian Shepherd, China Correspondent for The Washington Post.
