Environmental Pollution

The environmental problems in India are growing rapidly. The increasing economic development and a rapidly growing population that has taken the country from 300 million people in 1947 to more than one billion people today is putting a strain on the environment, infrastructure, and the country’s natural resources. Industrial pollution, soil erosion, deforestation, rapid industrialization, urbanization, and land degradation are all worsening problems. Overexploitation of the country's resources be it land or water and the industrialization process has resulted environmental degradation of resources. Environmental pollution is one of the most serious problems facing humanity and other life forms on our planet today.
With India's population at 1.2 billion people and counting, plus internal economic migration to urban areas from the countryside, the country's cities are bursting at the seams. Housing shortages, electricity and water cuts, traffic congestion, pollution and a lack of basic services are the reality for millions. The demographers are predicting that India will add three to four hundred million new people to its population over the next 40 years
About 45 per cent of India's land is degraded, air pollution is increasing in all its cities, it is losing its rare plants and animals more rapidly than before and about one-third of its urban population now lives in slums, says the State of Environment Report India 2009 brought out by the government.

AIR POLLUTION
The World Health Organization estimates that about two million people die prematurely every year as a result of air pollution, while many more suffer from breathing ailments, heart disease, lung infections and even cancer.Fine particles or microscopic dust from coal or wood fires and unfiltered diesel engines are rated as one of the most lethal forms or air pollution caused by industry, transport, household heating, cooking and ageing coal or oil-fired power stations.
There are four reasons of air pollution are - emissions from vehicles, thermal power plants, industries and refineries. The problem of indoor air pollution in rural areas and urban slums has assumed significant attention lately.
India’s environmental problems are exacerbated by its heavy reliance on coal for power generation. Coal supplies more than half of the country’s energy needs and is used for nearly three-quarters of electricity generation. While India is fortunate to have abundant reserves of coal to power economic development, the burning of this resource, especially given the high ash content of India’s coal, has come at a cost in terms of heightened public risk and environmental degradation. Reliance on coal as the major energy source has led to a nine-fold jump in carbon emissions over the past forty years. The government estimates the cost of environmental degradation has been running at 4.5% of GDP in recent years.
The low energy efficiency of power plants that burn coal is a contributing factor. India's coal plants are old and are not outfitted with the most modern pollution controls.

VEHICULAR EMISSIONS
Vehicle emissions are responsible for 70% of the country’s air pollution. The major problem with government efforts to safeguard the environment has been enforcement at the local level, not with a lack of laws. Air pollution from vehicle exhaust and industry is a worsening problem for India. Exhaust from vehicles has increased eight-fold over levels of twenty years ago; industrial pollution has risen four times over the same period. The economy has grown two and a half times over the past two decades but pollution control and civil services have not kept pace. Air quality is worst in the big cities like Kolkata, Delhi, Mumbai, Chennai, etc.
Bangalore holds the title of being the asthma capital of the country. Studies estimate that 10 per cent of Bangalore’s 60 lakh population and over 50 per cent of its children below 18 years suffer from air pollution- related ailments.

River water Pollution
Fully 80 percent of urban waste in India ends up in the country's rivers, and unchecked urban growth across the country combined with poor government oversight means the problem is only getting worse. A growing number of bodies of water in India are unfit for human use, and in the River Ganga, holy to the country's 82 percent Hindu majority, is dying slowly due to unchecked pollution.
New Delhi's body of water is little more than a flowing garbage dump, with fully 57 percent of the city's waste finding its way to the Yamuna. It is that three billion liters of waste are pumped into Delhi's Yamuna (River Yamuna) each day. Only 55 percent of the 15 million Delhi residents are connected to the city's sewage system. The remainder flush their bath water, waste water and just about everything else down pipes and into drains, most of them empty into the Yamuna. According to the Centre for Science and Environment, between 75 and 80 percent of the river's pollution is the result of raw sewage. Combined with industrial runoff, the garbage thrown into the river and it totals over 3 billion liters of waste per day. Nearly 20 billion rupees, or almost US $500 million, has been spent on various clean up efforts.
