1. Introduction
What is pollution?
Pollution is the introduction of contaminates into a natural environment that cause
instability, discorder of brain, harm or discomfort to the ecosystem.
Pollution hurt every livings being on the earth.
Human are the biggest producers of pollution.
Pollution is causing many illnesses.
Thesis: what is pollution? What is cause of pollution? What is effect of pollution?
Pollution: Pollution is the introduction of contaminates into a natural environment that
cause instability, disorder of brain, harm or discomfort to the ecosystem.
Cause of pollution: primary pollution cause and secondary pollution cause
Effect of pollution: pollution effect animal, human being, plant, tree etc
Body paragraph 1
Pollution is the introduction of contaminates into a natural environment that cause
instability, discorder of brain, harm or discomfort to the ecosystem. Pollution can take the
form of chemical substance or energy, such as noise, hear or light. Pollution hurts every
livings being on earth. Human are the biggest producers of pollution. Pollution will
shortern our life. There are main three types of pollution they are air pollution, water
pollution, and land pollution.
Air pollution: air pollution could be in the form of the emission of harmful chemical
gases .For example,(carbon monoxide)
Water pollution: water pollution could be in the form of any change in physical,
chemical, and biological properties of water which has a harmful effect on living being.
Land pollution: land pollution is can effect wildlife, plant, and human in many way.
40% of American rivers and 46% American cake are too pollution for fishing, swimming
or aquatic life. Air pollution is come from a wild variety of source. Example vehicles,
forest fire, dry soil erosion etc.

2. Body paragraph 2
What are the main causes of pollution?
The Human being itself is the main cause of pollution.
We cause air pollution directly through our use of electricity, fuels, and transportation.
We also cause air pollution indirectly, when we buy goods and services that use energy in their
production and delivery. Most of this air pollution we cause results from the burning of fossil fuels,
such as coal, oil, natural gas, and gasoline to produce electricity and power our vehicles.
People pollute the water with chemicals and other hazardous materials. Human agency may be
the most understated cause of water pollution. Of course we pollute passively on a large scale,
merely by using the systems set up for us to exist and thrive.
What can cause pollution?
Trash, greenhouse gases, almost anything.
Unfortunately, humans cause pollution from cars and factories and etc
exhaust, smoke, litter and cutting down trees.
Throwing household garbage, using old vehicles, smoking, using pesticides and insecticide
1) Air pollution cause by the burning of fuel that directly release
hazardous chemical into air.
2) Water pollution cause by directly incorporation of hazardous
pollutants.
3) Land pollution cause by domestic and nuclear wastes, industrial
water.
Body paragraph 3

3. Environmental Pollution Effects on Humans
Air Pollution Effects
1) Reduced lung functioning.
2) Reduced energy levels
3) Cancer
Water Pollution Effects
Waterborne diseases caused by polluted drinking water
1) Typhoid.
2) Hookworm.
Soil Pollution Effects
1) Causes cancers including leukaemia.
2) Lead in soil is especially hazardous for young children causing developmental damage to
the brain.
Environmental Pollution Effects on Animals
Effects of Pollution on Animals - Air Pollution
1) Acid rain (formed in the air) destroys fish life in lakes and streams.
2) Ozone in the lower atmosphere may damage lung tissues of animals.
Effects of Pollution on Animals - Water Pollution
1) Chemical contamination can cause declines in frog biodiversity and
tadpole mass.
2) Too much sodium chloride (ordinary salt) in water may kill animals.

4. Effects of Pollution on Animals - Soil Pollution
1) Small life forms may consume harmful chemicals which may then be
passed up the food chain to larger animals; this may lead to increased
mortality rates and even animal extinction.
Environmental Pollution Effects on Trees and Plants.
Air Pollution
1) Acid rain can kill trees, destroy the leaves of plants, can infiltrate soil by
making it unsuitable for purposes of nutrition and habitation.
Water Pollution
1) May disrupt photosynthesis in aquatic plants and thus affecting
ecosystems that depend on these plants.
2) Plants may be killed by too much sodium chloride (ordinary slat) in
water.
Soil Pollution
1) May alter plant metabolism and reduce crop yields.
2) Trees and plants may absorb soil contaminants and pass them up the
food chain.
