POLLUTION IN MODERN WORLD



         I am writing this blog to keep people aware of pollution and how we are polluting our environment. I invite people to lend hands against pollution which is a threat to living beings.
        
         Pollution is the introduction into the air, water or ground of toxic substances that are damaging to human health and ecosystems . It is mainly linked with human activity: discharge of domestic, industrial and agricultural waste; application of pesticides by farmers; leaks of radioactive materials; gas emissions into the atmosphere etc., As a developing country India is also facing the problem of pollution.

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, lack of wate disposal management system and land degradation are all worsening problems. Over exploitation 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.




         India's per capita carbon dioxide emissions were roughly 3,000 pounds (1,360 kilograms) in 2007, according to the study. That's small compared to China and the U.S., with 10,500 pounds (4,763 kilograms) and 42,500 pounds (19,278 kilograms) respectively that year. The study said that the European Union and Russia also have more emissions than India.
 
Wates from industries:
           Most of the industrial wastes are directly fed into lake or rivers or waste lands, and thus polluting the soil. Due to lack of knowledge about the harmful effects of such chemicals the wastes are dumped into the river sides. Waste disposal management systems are also not properly implemented which may even worse the situation. Smoke from power plants and other industries are directly emitted to the atmosphere without treating the toxic gases.


India and US clean energy pact:
       India and the U.S. on November 8, 2010 inked an agreement to establish a bilateral energy cooperation programme to promote clean and energy-efficient businesses, Indian and U.S. companies inked joint venture deals worth $175 million in the renewable energy sector.
       The US President Barack Obama and Prime Minister Manmohan Singh announced the setting up of Joint Clean Energy Research and Development Centre. The proposed centre is part of the Partnership to Advance Clean Energy (PACE), which forms the core of the “green partnership”. Funding for the centre is expected from national budgets and the private sector. Each government proposes to commit $25 million over the next five years. A Comprehensive environmental assessment of industrial clusters, undertaken
by IIT Delhi and the CPCB, found that the environmental pollution levels in 10 major industrial hubs had reached a “very alarmingly high” level. The World Bank Group has sanctioned two loans worth around Rs1,185 crore for environment management projects in India on July 22, 2010. Of this, Rs897crore will go for the Integrated Coastal Zone Management (ICZM) project and the remaining for Capacity Building for Industrial Pollution Management project.




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 increased.
       A latest example industrial pollution is the leak of chlorine gas in Mumbai. On July 14, 2010 nearly 76 people were treated in hospital on after chlorine gas leak from an industrial area in Mumbai. The land owned by the Mumbai Port Trust is an industrial area mainly used for storage and delivery of cargo and containers.



Aircraft pollutants:
          According to a study published in the journal
Environmental Science and Technology (EST) in the first week of October 2010, almost 8,000 people will die due to aircraft pollutants this year, and 3,500 of them would be from India and China. Experts say this means people exposed to such pollutants will also suffer from respiratory diseases.
A recent report by Massachussets Institute of Technology (MIT) researchers says that the harmful pollutants emitted by an aircraft at an altitude of 35,000ft are fatal for people. The report says that nitrogen and sulphur oxides emitted by aircraft at approximately 35,000ft combine with other gases in the atmosphere to create noxious particulate matter.
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 big cities like Kolkata, Delhi, Mumbai, Chennai, etc.    According to the Society of Indian Automobile Manufacturers, India’s auto production has doubled from 7 million units in fiscal year 2004 to over 14 million units in fiscal year 2010 largely on the back of a buoyant domestic market.
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.

CHENNAI:  

        Exhaust from vehicles, dust from construction debris,
industrial waste, burning of municipal and garden waste are all on therise in the city. So are respiratory diseases, including asthma. At least six of the 10 top causes of death are related to respiratory disease, says Dr D Ranganathan, director (in-charge), Institute of Thoracic Medicine.


Mumbai: 

    Not only are levels of Suspended Particulate Matter above
permissible limits in Mumbai, but the worst pollutant after vehicular emissions has grown at an alarming rate. The levels of Respirable Suspended Particulate Matter (RSPM), or dust, in Mumbai’s air have continued to increase over the past three years.


  The air pollution in Mumbai is so high that Mumbai authorities have purchased 42,000 litres of perfume to spray on the city’s enormous waste dumps at Deonar and Mulund landfill sites after people living near the landfill sites complained of the stench. The Deonar landfill site, one
of India’s largest, was first used by the British in 1927. Today, the festering pile covers more than 120 hectares and is eight story's high.



Bhopal: 
     Bhopal gas tragedy was the greatest industrial disaster in the world that took place at a Union Carbide pesticide plant in the Indian city of Bhopal, Madhya Pradesh. At midnight on 3 December 1984, the plant accidentally released methyl isocyanate (MIC) gas, exposing more than
500,000 people to MIC and other chemicals. The first official immediate death toll was 2,259. The government of Madhya Pradesh has confirmed a total of 3,787 deaths related to the gas release Others estimate 8,000-10,000 died within 72 hours and 25,000 have since died from gas-related diseases, making it the deadliest man-made environmental disaster in history.


On July 14, 2010 Chlorine gas leaked from the Sewri industrial area on land owned by the Mumbai Port Trust and nearly 76 people were treated in hospital.


The effects of air pollution are obvious: rice crop yields in southern India are falling as brown clouds block out more and more sunlight. And the brilliant white of the famous Taj Mahal is slowly fading to a sickly yellow. In the “Tajmahal Case” a very strong step was taken by Supreme Court to save the Tajmahal being polluted by fumes and more
than 200 factories were closed down.


Birds and species affected: 

   Studies conducted by the high altitude zoology field station of the Zoological Survey of India (ZSI) based in Solan town of Himachal Pradesh have recorded a drastic fall in butterfly
numbers in the western Himalayas, famous for their biodiversity.The population of 50 percent of the 288 species recorded in the western Himalayas, comprising areas of Himachal Pradesh and Jammu and Kashmir, have declined more than half in just 10 years.
