30-year eco-transformation of Xiamen, China, inspires global sustainable development efforts.

30-year eco-transformation of Xiamen, China, inspires the world. Professor William Brown, a US resident in Xiamen for 30 years, witnessed the city's ecological revival from a choked, smelly lake in 1988 to a haven of clear waters, lush greenery, and thriving wildlife today. Brown and UN ocean envoy Peter Thomson hope more cities learn from Xiamen's example of sustainable growth and green development.
