In the last two decades, the rapidly growing Chinese economy has won great global attention. But that economic growth was at high environmental costs, including serious environmental pollution and ecological deterioration. The country, therefore, faces a big challenge to maintain its economic growth without further undermining the natural environment. This book is an attempt to seek both a theoretical and a practical solution to meet that challenge. Yanling Zhang calls the potential solution "a solution with two legs": to develop environmental protection industry further, and to put industrial ecology into place.
