In Wuhan, greenway around lake is paying off

The East Lake in Wuhan, Hubei province, wasn't happy. China's largest lake inside a city, with a surface area of 33 square kilometers, it suffered from noise and air pollution - the result of heavy traffic - as well as soil and water pollution.

But a long-term greenway project has helped turned things around. The project, a belt of green space that encircles the lake, has helped improve the water quality and provides a pleasant environment where people can relax.

The lake, which lies along the Yangtze River's south bank in downtown Wuhan, is now an eco-tourism scenic spot.
