Since the end of the 20th century with the development of eco-agriculture, "green consumption"has become more prevalent in people's life in China. Urban residents tend to choose agricultural products in the supermarket that have not been sprayed with pesticide, for instance. Some industrial products, like recycled paper, have become "green," and manufacturing refrigerating equipment with CFC (chlorofluorocarbons) has been banned. Green products form a large market with an estimated annual value of 55 billion yuan.
