... the idea of Gaia is anticipated most clearly in a line from the Tao Te Ching, the oldest Taoist scripture. In ancient Chinese rituals, straw dogs were used as offerings to the gods. During the ritual they were treated with the utmost reverence. When it was over and they were no longer needed they were trampled on and tossed aside: 'Heaven and earth are ruthless, and treat the myriad creatures as straw dogs.' If humans disturb the balance of the Earth they will be trampled on and tossed aside. Critics of the Gaia theory say they reject it because it is unscientific. The truth is that they fear and hate it because it means that humans can never be other than straw dogs.
