Ma Jun: China's environmental patriot

HONG KONG (AFP) — In China, where dissent is often brutally suppressed, publicly shaming powerful corporations for destroying the environment is fraught with risk. Ma Jun treads carefully.

The author of "China's Water Crisis," a savage catalogue of the country's environmental collapse, Ma now takes the fight to polluters, shaming factories on a website run by his non-governmental organisation the Institute of Public and Environmental Affairs (IPE).

And working out how far a small campaign group can push businesses -- and the officials who back them -- has become his specialty.

"There is a space there, but there is a line as well. The key is to understand both," said the soft-spoken 40-year-old.
