Be aware of Western climate change tactics

I keep coughing after a brief visit to a sizable developing nation - not because of a possible A(H1N1) infection but the continuous exposure to strong smell of fuel and pollutants on roads of the country, where 20-year-old obsolete cars rattled everywhere.

Coincidentally, a colleague of mine talked to me about one mountainous country he lately toured, saying that air pollution there was roughly 10 times, though he failed to supply scientific data, of that in Beijing.

While many Beijing residents, including foreign expatriates, are still not satisfied with air quality in the city, the government of the Chinese capital is implementing one of the world's harshest vehicle emissions rules, particularly after 2008 when Beijing hosted a summer Olympics. The improvement is noticeable.
