This is not going to be about a Pink Floyd story, but one about the Worlds worst air pollution.

The air at the Beijing Olympics has been hazy, heavy and humid. Athletes have voiced concerns over the potential impact to their health and performance. Beijing’s air pollution regularly reaches levels two or three times above what the World Health Organization considers safe.

Beijing officials on Friday continued to insist that the murky haze enveloping the city is not the result of pollution, but instead is fog created by moisture vapor in the air. Visibility, they say, is not necessarily an indicator of air quality.

Have you ever been to Hong Kong or Beijing? You can smell gas and sulfur in the air. It can be very harmful for visitors who are not exposed to such pollution levels all the time.

How will the Athletes over come this major issue? I recommend they stay indoors as much as possible and drink a lot of water.

In fact, the Olympic Committee has said that it may be postpone endurance events, including the marathon, if pollution levels are too high.

China has invested billions in “greening” the capital, and implemented drastic measures to ensure air quality for the Olympics. Last month, some 2 million cars were taken off roads, constructions sites were shut down and dozens of factories were closed across the capital. Similar measures were taken in surrounding provinces.
