Air pollution in india

The rapidly growing population and economic development are leading to the environmental degradation in India through the uncontrolled growth of urbanization and industrialization, expansion and massive intensification of agriculture, and the destruction of forests.It is estimated that the country’s population will increase to about 1.26 billion by the year 2016. The projected population indicates that India will be the first most populous country in the world and China will be ranking second in the year 2050[1]. India having 18% of the world's population on 2.4% of world's total area has greatly increased the pressure on its natural resources. Water shortages, soil exhaustion and erosion, deforestation, air and water pollution afflicts many areas.
Indian cities are polluted by vehicles and industry emissions. Road dust due to vehicles also contributing up to 33% of air pollution.In cities like Bangalore, around 50% of children suffer from asthma. India has emission standard of Bharat Stage II (Euro II) for vehicles since 2005.
On of the biggest causes of air pollution in India is from the transport system. Hundreds of millions of old diesel engines continuously burning away diesel which has anything up to 200 times the amount of sulphur out European diesel has. Of course the biggest problems are in the big cities where there are huge concentrations of these vehicles. On the positive side, the government appears to have noticed this massive problem and the associated health risks for its people and is slowly but surely taking steps. The first of which was in 2001 when it ruled that its entire public transport system, excluding the trains, be converted from diesel to compressed gas (CPG). Electric rickshaws are being designed and will be subsidised by the government but the supposed ban on the cycle rikshaws in Delhi will require a huge increase on the reliance of other methods of transport, mainly those with engines. In this case it seems, one step forward two steps!
It also appeared that the excessive pollution was having an adverse effect on the Taj Mahal. After a court ruling all transport in the area was shut down shortly followed by the closure of all industrial factories in the area. The air pollution in the big cities is rising to such an extent that it is now 2.3 higher than the amount recommended by WHO (world health organisation).The rapidly growing population and
economic development are leading to the environmental degradation in India through the uncontrolled growth of urbanization and industrialization, expansion and massive intensification of agriculture, and the destruction of forests.
