The Industrial Revolution in Europe first saw the beginning of air pollution, which gradually became a major global problem.
The major air-polluting industries are iron, steel and, cement.
Of the 35-40 million tonnes of flyash generated annually by thermal power plants in India, only 2-3 percent is productively utilized.
The worst industrial disaster in India, occurred in 1984 in Bhopal the capital of Madhya Pradesh. A deadly chemical, methly isocyanate leaked out of the Union Carbide factory killing more than 2500 and leaving thousands sick. In fact the effects of this gas tragedy is being felt even today.
Every year some 50million cars are added to the world’s roads. Car making is now the largest manufacturing industry in the world.
In India the number of motorized vehicles have increased from 0.2 million in 1947 to 36.3 million in 1997.
Major contributor to Delhi's air pollution are vehicles.
Nearly three-fourths of India's population, which is rural, bears 84% of the burden of exposure to air pollution.
Growing population, poverty, and inadequate access to clean fuels in rural areas have perpetuated the use of biomass, thereby condemning more than 90% of rural households and more than 35% of urban hoseholds to high levels of indoor air pollution.
One of the most important measure to counter pollution is planting trees. With neem and peepal being the largest emitters of oxygen, planting them in the gardens purifies the surrounding air and helps in maintaining hygienic conditions. While champa, mogra and chameli have better chances of surviving pollution in summer, bulbous varieties do better in winter.

The first kind of PENCIL was a bunch of GRAPHITE sticks held together by string. Then someone decided it would be better to push the graphite into the inside of a hollow wooden stick.
JOSEPH RECHENDORFER was the first person to think of putting a piece of rubber onto the top of a pencil which makes it real easy to rub out mistakes.
Did you know that the average lead pencil can draw a line that is almost 35 miles long or you can write almost 50,000 words in English with just one pencil? Amazing fact! Now imagine an eraser that could match it !!!
