Only few greedy people but they affected millions. We need to learn fast on many things, laws, pollution, science, and education. One simple mistake can cause disaster for generations!

China's pollution problems are blamed on the country's rapid urbanisation and dramatic economic development. But experts have raised questions over China's will and ability to tackle car and coal use, which are seen as key causes of the phenomenon. The Beijing News went as far as to suggest banning or regulating next month's traditional and hugely popular New Year fireworks in the capital. Pollution readings spiked last year after the city's skyline lit up with explosions. The toxic air follows an extreme bout of pollution earlier this month, when state media said readings for PM 2.5, particles small enough to deeply penetrate the lungs, peaked at 993 micrograms per cubic metre, almost 40 times the World Health Organization's recommended safe limit.http://thestar.com.my/news/story.asp?file=/2013/1/29/reutersworld/1301291615-off-the-scale-smog-envelops-beijing-aga&sec=reutersworld
