Pollution is the process of making the environment land water and air dirty by adding harmful substances to it. Pollution causes imbalance in the environment. This imbalance has threatened the very survival of all forms of life. It is a threat to the whole world. India ranks a low 125 out of 132 countries in the Environmental performance Index 2012. This report is produced by the researchers of Yale and Columbia University in association with the World Economic Forum.
Environmental pollution is a serious problem of the industrialized societies. The industrial development and the Green Revolution have adversely affected the environment. People have converted the life supporting system of the entire living world into their own resources and have vastly disturbed the natural ecological balance. Serious degradation and depletion have been caused due to the overuse, misuse and mismanagement of resources to meet the human greed.
Environment pollution is defined as the unfavorable alteration of our surroundings. It is a by product of man’s activities which directly or indirectly are responsible for the changes in environment. These changes could be in the physical chemical or biological characteristics of land air or water that harm human life and other living things. Population explosion, rapid industrialization deforestation unplanned urbanization scientific and tech logical advancement etc. The major causes of environmental pollution. Nearly 35 percent of India total land area is subjected to serious environmental pollution. Three fourths of the earth consists of water yet there is scarcity of potable water. In India allay the sources of water lie rivers lakes ponds and wells have been polluted and are unfit for drinking. As a result of the increased use of fertilizers, the rivers seas and oceans have become contaminated with harmful pollutants.
Industrialization has led to urbanization. The migration of rural population to the cities in search of work has created an unhealthy environment. It has led to overcrowding and establishment of slum areas. Towns and cities are full of smoke ,fumes dirt dust rubbish gases foul smell and noise.
Nuclear explosions and nuclear tests also pollute the air. The spread of radioactive materials into the air has increased. This radioactive pollution may cause cancers, abnormal births and mutations in men.
The Taj Mahal in Agra is affected by the fumes emitted by the Mathura refinery. Reports estimate that the monument would get defaced within a span of twenty years because of the harmful effluents of the emission from the refinery.
Water pollution adversely changes the quality of water. It disturbs the balance of the ecosystem and causes health hazards. Water becomes polluted by the presence or addition of inorganic and organic or biological substances. Industrial effluents which are dumped into the rivers further add to the water pollution levels.
Soil pollution usually results from the disposal of solid and semi solid wastes from agricultural practices and from insanitary habits. The soil gets heavily polluted by hazardous materials and micro organisms, which enter the food chain or water and create numerous health problems.
The emission of greenhouse gases has led to climatic changes. The increase in pollution has resulted in global warming. Global warming is an average increase in the Earth temperature due to greenhouse effect as a result of both natural and human activity. The term climate is often used interchangeably the term global warming. The ice caps in the polar regions have begun to melt fast. This has resulted in the rise of the water level of the seas and oceans. Grass sprouting in Antarctica and snowfall in the desert of the united Arab emirates are all the warning signals of global warning.
Pollution causes different types of diseases. Air pollution causes allergies asthma lung cancer and bronchitis. Radioactive pollutants cause respiratory problems paralysis cancer and other disease .Excessive noise pollution can lead to deafness anxiety stress increase in the rate of heartbeat and other health problems.
In order to fight this menace of pollution vigorous efforts should be made the anti pollution law should be strictly implemented. In order to check water pollution sewage and the factory waste should be planted everywhere and vehicles should be made eco friendly.
Public education and awareness of the relationship between climate change and human health is a key to deal with these problems more effectively.
General awareness is a must to save our planet from destruction. A ll the nations of the world should work united to control environmental pollution.
Answer:
Pollutions
Explanation:
The natural mechanisms of the Earth that kept been working in sync since the formation of the Earth are fibbing in confusion. This can be attributed to the exploitation of biological resources by humans. We, occupying the best strata on the ecological pyramid, should be aware of the environment. Corruption includes been a flaming issue for the previous 100 years, though little includes been done to bring steps towards rebuilding our ecosystem and protecting it from the point of collapse. Any undesirable substance that can disrupt the functioning of a biological system can be classified as a pollutant.
Some pollutants don’t have anybody or size. For instance, a temperature rise in our atmosphere by rare degrees for a short time will not have any significant effect, but the exact amount of increase in temperature in a water body will destroy the thermo-sensitive organisms. Here, the temperature exists as a pollutant for the water body. There are certain hidden pollutants, too, like noise. Noise pollution wasn’t even recognized as a state of Pollution until the late 1970s. In 1972 it was identified as a significant form of Pollution by the United States’ Pollution Control Board. Noise pollution exists the most problematic to deal with, as it has no exact guidelines. Your neighbor partying in the center of the night with stereos blasting music at a dangerously high level again slips under noise pollution. A deep sense of responsibility towards nature and compassion for all the organisms residing on Earth will go a long way in protecting our planet from devastation.
