One of Mao Zedong's most widely known and often quoted slogans perfectly encapsulates his philosophy of confrontation: It is a delight to struggle with Heaven and Earth. Obviously, people no longer see things in quite that way. In 2007, for the first time in the history of the Communist Party of China (CPC), the notion of an "ecological civilization" was included in its administrative program, making the construction of an environmentally friendly society a cornerstone of China's long-term development strategy. In September 2008, the China Ecological Culture Association was founded. Comprised of 12 branches–such as forest culture, grassland culture and desert culture–its aim is to "develop an ecological culture, promote a green environment and build an ecological civilization."
