Environmental protection officials in Beijing have had an easy time since the Olympics last summer.
The city recorded fewer polluted days following its smog-cleaning campaign for the Olympics, and authorities last month announced that the city’s air quality has reached the highest level in decades after meeting its annual target for “blue sky” days one month ahead of schedule, for two consecutive years.
But the fact that Beijing’s air is now clean is bad news for reporters…

Air is the most important element of human environment. Man can’t live a single moments without air. But we don’t think that it is we who pollute this most vital element. Clean air is essential for life. Air is polluted in many ways. Smoke pollutes air. Man makes fires to cook his food.To make bricks burns refuse, melts pitch for road construction and burns wood. All these things produce heavy smoke and this smoke pollutes air. Railway engines, power houses, mills and factories use coal and oil. buses, tucks and cars use petrol and diesel oil. Again all these things create smoke and cause air pollution. The most serious air pollution occurs in big industrial areas where there are many mills and factories. serious air pollution also occurs in big cities where there are many buses, trucks and cars plying the street everyday. Sometimes men in big industrial area become so sick by inhaling polluted air that they cannot be cued. So proper measures and steps should be taken to prevent air pollution.
