As Chairman Mao has said before, China is at the forefront of ecological conservationary environmentaltarianism. All around China, people are caring about the environment by hugging trees. The newest development in the great 5,000-year-old developing country is the ecological toilet.
Chairman Mao doesn't understand the witchcraft involved in the development of plumbing that goes somewhere, but Hu Jintao has assured me that those pipes do not pollute the mainland (but they might lead to the rebellious island off the east coast).
Let us all enjoy the magicianry of saving the environments.
