Those days might be over, as BusinessWeek reports.

China has some of the most polluted cities in the world, a consequence of the country’s rapid economic development. More than 320 million people in China drink unsafe water, according to Greenpeace China. The country’s Environmental Protection Administration considers 45% of the rivers and waterways it monitors to be unsuitable for human contact, says Greenpeace.

Now, after years of silent suffering from the effects of filthy air and dirty water, many Chinese are saying they’ve had enough. And in some cases, their protests are turning violent.

This may be one of the issues that cracks the Chinese government’s grip on power. The situation in China is dire, and the people are awakening to the seriousness of the problem. This is good for China and the rest of the world.

As reported earlier, the Chinese are making huge investments in wind and solar, and this poses a threat to the US from a manufacturing point of view, but naturally these investments are a positive step for the entire world and the green economy. But this isn’t enough to address the pollution crisis in China. China needs to enact and enforce real regulations preventing companies from polluting the environment. They need to change the manufacturing culture. Until that happens, they will be facing ever-increasing protests and possible social unrest that can destabilize the regime.
