The Beijing Olympics are drawing international attention to China’s chronic pollution problem.

Environmental damage costs China more than $200 billion a year, or roughly 10 percent of its GDP. The country recently pledged to spend up to $125 billion on a massive cleanup, including the construction of over 10,000 wastewater treatment plants.

This makes Singapore’s water treatment companies well worth a look, according International Strategist editor Tom Dyson in DailyWealth.
