Youngsters get a close look at eco concerns facing the planet. Yang Feiyue reports from Hangzhou.

Aboard the little train, schoolchildren scream as tsunamis crash down on the city, food-producing fields are turned into desert, fires destroy pristine forest, iconic animals become extinct, and a poisonous haze causes people to choke and planes to drop from the sky. Finally, as the icecaps melt, a vast wall of water rushes towards me, I hold my breath - then take off my glasses.

Along with a number of shrieking schoolchildren, I have just glimpsed the future through 3-D glasses - and it's a scary sight. I'm in the Global Warming section on the second floor of one of China's few low-carbon themed facilities, the Hangzhou Low Carbon Science and Technology Museum, experiencing the perils of global warming and what might happen unless we take better care of the planet.
