Don’t be mistaken, these cyclists are not donning mask to filter out H1N1 virus. They are wearing the protective face cover to prevent sand and grit from getting into their lungs. This scenario is in China where sandstorms are getting very common. Scientist doesn’t know yet why the storms are getting so prevalent. It could be change in climate or perhaps too the deserts growing in size due to drought. Anyway, according to a World Bank report, 16 out of the 20 most polluted cities in the world are situated in China. China has of late being inundated with air pollution. On a bad day, whole cities can be shrouded in fine mist, and people going to work have to endure with traffic congestion due to poor visibilities. It was during the Beijing Olympics that vehicles were forced to be allowed on the streets on consecutive days; this to cut down on the number of cars in order that the air be cleared of smog. But looking at the pace of development in China, there is no telling when China can get a fresh envelope of clean air space. In the meantime, people will have to wear face mask, like wearing clothing!
