Pesticides: hidden ingredients in Chinese tea

Tea drinking is one of China's most cherished customs; and tea a symbol of Chinese culture. Today, China is the world's biggest tea producer, with 20 tea-producing provinces and eight million tea growers. And the area of tea plantations and annual tea output in the country is on a continuous rise. However, the latest Greenpeace investigation has discovered that the massive use of chemical pesticides is seriously affecting the safety of tea in the Chinese market.
