What’ s happening to planet Earth?

It’s heating up.

It’s coughing. It’s melting.

It’s wounded.

POLLUTION

What is

Pollution happens when the environment is contaminated or

dirtied by waste, chemicals, gases and other harmful substances.

There are four main forms of pollution

Pollution

Noise pollution

Water pollution

Air pollution

Land pollution

Air Pollution

Air 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.

Form CausesA cloud of smoke from the exhaust of a vehicle

Increasing traffic

Smoke from a factory chimney

Growing cities

Eruption of a volcano Rapid economic development

Cigarette smoke IndustrializationBurning leaves Apathetic people

Effects of Air Pollution-Health problems

-Damage to the environment-Damage to property

-Thinning of the protective ozone layer of the atmosphere which is leading to

climate changes

Birth defects

cancerRespiratory

problems Heart disease Asthma

Tuberculosis Immune system

damageIntellectual disorders

Some Solutions to Air Pollutionshould / share vehicles or use public transport to go to

workshould / get a regular pollution check for our vehicles

should / walk or use bicycles to go to near placeschimneys of factories should be fitted with proper

filters to prevent smokes from coming out and effect the atmosphere

conserve energy:switch off fans and lights when you are going out

Water Pollution

Water Pollution

Water pollution is 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.

Form Cause

Toxic substances dissolve in water or gets deposited on the

bed.

City sewage

Toxic substances enter lakes, rivers, streams, etc.

Industrial waste

Pollutants go down into the ground.

Agricultural run-off

Effects of Water PollutionDevastating to people and animals,

fish, and birds.Unsuitable for drinking,

recreation, agriculture, and industry.

Destroys water life.

Diarrhea Vomiting Typhoid Diphtheria

Hepatitis Kidney Damage Nerve Disorders Skin Lesions

Some Solutions to Water PollutionFactories should not throw their

wastes in water bodiesPeople should not bath or wash

clothes in rivers or lakesPeople should not take their animals

to bath in riversor lakes

Land Pollution

Land Pollution

is 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.

Types of wasteHousehold

wasteIndustrial wasteBiomedical or hospital waste

Causes Population increases

Increased plastics products

Changes in lifestyleLandfills not well

equipped to protect against contamination

Effects of Land PollutionOver 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.

Since 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.

Some Solutions to Land Pollution

People should plant more treesPeople should not throw rubbish in the streets , instead they should use

litter binsIndustries should not throw their

wastes on land

Noise Pollution

Noise Pollution

Sound is essential to our daily lives, but noise is not. Noise is generally used as an unwanted sound, or sound which produces unpleasant

effects and discomfort on the ears.

Causes-Road traffic

-Factories-Loud speakers and other

loud speaking things-Jet planes

-Cinema halls-Household equipments

-Plumbing, boilers, generators…

EffectsTemporary or

permanent deafnessHeadaches and earaches

The physiological manifestations are stress,

irritability and nervousness, feeling of fatigue and decreases

work efficiency.

Some Solutions to Noise Pollution

People should not use lous speakersFactories should be made out of the

citiesThere should not be more noise

making vehicles on the roads
