City of dreams

摘要

Ideas about tackling China's myriad environmental woes, from soil erosion to polluted waterways, tend to come in outsize packages-hardly surprising, given the scale of the damage. Bold environmental solutions are as appealing to policymakers as they are to engineers who want to put their stamp on the cities of tomorrow. One such project is Dongtan, a planned eco-city on an alluvial island near Shanghai. Designed by Arup, a British design firm, to house 500,000 people on a 8,600-hectare (21,250-acre) site, it was billed as a low-carbon alternative to urban sprawl and a blueprint for other eco-cities. But four years on, not a single green building has gone up on the site.
