Pollution contributes to the harmful environment that results in adverse effect on living beings. It is one of the major concern areas for the whole world. It is a global issue involving the United Nations, governments, voluntary institutions and the media.
Students need to be made fully aware of the adverse effects of rising pollution. Also, being the future generation, they can play a vital role in controlling pollution if they are familiar with this threat to the survival of mankind.Anything added into the environment that results in producing harmful or poisonous effect on living things is called pollution. Pollution is the process that makes nature’s resources such as land, water, air or other parts of the environment unsafe or unsuitable to use. Pollution can be of many types: soil, air, water, thermal, radioactive, noise, and light. The toxins released are inhaled by each one of us while we breathe.
Pollution and its Causes
Inhaling poisonous air is as hazardous as smoking. It is not only the humans who are affected from this polluted environment but also the animals. Air is filled with highly toxic gases. These dangerous gases in environment are released by the power industries that burn fossil fuels, industries that dispose wastes in the water, farmers using pesticides, high usage of artificial lights and loud sounds, etc. Each of these leads to generation of the life threatening cause – pollution.
Pollution load on rivers has increased over the years due to rapid urbanisationand industrialization. Abstraction of water for irrigation, drinking, industrial use, power etc. compounds the challenge. Discharge of untreated wastewater from towns along the rivers constitutes the major source of pollution load in rivers. According to a recent report of the Central Pollution Control Board (CPCB), against an estimated sewage generation of about 38254 million litres per day (mld) from the Class I cities & Class II towns of the country, the available treatment capacity is for 11787 mld.
Conservation of rivers is a collective effort of Central and State Governments and the Central Government is supplementing the efforts of the State Governments in river conservation through the Central Plans. Creation of infrastructure for sewage management and disposal is also being undertaken through other Central schemes, such as Jawaharlal Nehru National Urban Renewal Mission and Urban Infrastructure Development Scheme for Small and Medium Towns, as well as under state schemes.
The National River Conservation Plan (NRCP) presently covers 39 rivers in 185 towns in 20 states. Pollution abatement works taken up under the Plan include interception and diversion of raw sewage, setting up of Sewage Treatment Plants etc. A Sewage treatment capacity of 4417 million litres per day (mld) has been created so far under the Plan. Details of funds released state-wise under NRCP till March, 2011 are given at Annexure.
