is the sum of the total of the elements, factors and

conditions in the surroundings which may havean impact on the development, action or survival of

an organism or group of organisms, such as, we

human beings.

Importance of the natural environment

Natural environment is of crucial importance for social and

economic life. We use the living world as

a resource for food supply an energy source

a source for recreation

a major source of medicines

natural resources for industrial products

In this respect the diversity of nature not only offers man a vast power

of choice for his current needs and desires. It also enhances the role of

nature as a source of solutions for the future needs and challenges ofmankind.

Humans have had the ability to change their environment for

thousands of years. Today this ability is greater than ever. This

is because there are more people living now than ever before

and human activity is concentrated in huge cities. Also, scienceand technology allow us to interfere with natural processes in

more direct ways. Environmental pollutionthreatenshuman

health.

Any undesirable change in physical , chemical or biological

characteristics of air , land , water or soil, that is likely to have

an adverse effect on the natural environment or life, is termed

as environment pollution. The three major types of pollutions

are:

Air Pollution

Water Pollution

Land (soil) Pollution

Environmental Pollution

Air pollution is actually harmful substances in the

atmosphere, which damages the environment.

With the development of industries, came along

the increase in air pollution.

Air Pollution

h

Polluted air contains one, or more, hazardous substance,

pollutant, or contaminant that creates a hazard to general

health. It is usually measured in terms of "particulate matter",

or, the number of particles of these potentially hazardous

substances as a percentage of air. Air pollution in cities causesa shorter lifespan for city dwellers.

The key Health Problems

caused by Air Pollution

Asthma Cancer Respiratory problems Heart disease

Birth defects Intellectual disorders Tuberculosis Immune system damage

Water pollutionis the contamination of water bodies

(e.g. lakes, rivers, oceans, groundwater).

Water pollution occurs when pollutants are discharged

directly or indirectly into water bodies without

adequate treatment to remove harmful compounds.

Water Pollution

of Water Pollution

Infectious diseases such as typhoid and cholera can be

contracted from drinking contaminated water. This is called

microbial water pollution. The human heart and kidney heart s

can be adversely affected if polluted water is consumed

regularly. Other health problems associated with pollutedwater are poor blood circulation, skin lesions, vomiting, and

damage to the nervous system. In fact, the effects of water

pollution are said to be the leading cause of death for humans

across the globe.

Land Pollutionis the degradation of Earth's land

surfaces often caused by human activities and their misuse of

land resources. It occurs when waste is not disposed properly.

Health hazard disposal of urban and industrial wastes,

exploitation of minerals, and improper use of soil by inadequate

agricultural practices are a few factors.


13/21

Over a long period of time, landfills start to emit landfill gases.

Landfill gas is produced due to the anaerobic conditions that

organic wastes decomposed in.Most waste buried in landfills give rise to hazardous and toxic

liquids known as leachates. These leachates contaminate

water sources, like the ground water below the landfills,

leading to water pollution.Besides the points mentioned above, it is also important to

note that these over-crowded dumps, contaminated sites and

careless disposal of waste also contributes to air and water

pollution, as well as, acid rain.

Impact of Land Pollution


14/21

The key Health Problems Caused

by Land PollutionSince direct impacts of land pollution are air pollution and water

pollution, the key health problems caused by land pollution are same

as those of air pollution and water pollution and the additions are

increased human injuries, from syringes, broken glass and cans

washing onto river banks and beaches.

Environmental Pollution

a major concernAbating pollution is an exceptionally important

concern because of pollutions harmful effects on the

persons health, on climate and on the environment.

Everybody is a stakeholder as we are all inhabitants of this one and only mother

earth.

Everyone should therefore be personally responsible for the upkeep of the

environment through cooperation and active participation in making the

atmosphere pollution free.


16/21

Children may also share the responsibility

Lots of people are still unaware of the detrimental effects of pollution.

Children can also help controlling

pollution by informing and educating

people about pollution, in different

ways. Some are like these:
