In a sign of increasing international concern about the ecological challenges posed by China, one of the world’s most prominent greens has moved to Beijing and set up shop as an environmental consultant. For more than three decades, Canadian Maurice Strong has been a major player in global diplomacy, environmental and otherwise; earlier this month, he intervened in the North Korean nuclear crisis as a special envoy for U.N. Secretary-General Kofi Annan. Now, Strong plans to help tackle pollution, deforestation, pesticide use, and other environmental problems in China by advising business and government on ecological matters. A forceful critic of U.S. environmental policies, Strong hopes to transform China into a world leader on ecological issues.
