Of Air & Water.

4. Concept Of Pollution
Pollution can be natural such as volcanic ash.
Can also be created by human activities such as trash or runoff
produced by factories.
Pollution damage the air, water, and land quality.
Many things that useful to humans that produce pollution.
Car spew pollutant from their exhaust pipes.
Burning of coal to create electricity pollutes the air.
Industries and homes generate garbage and sewage that can pollute land
and water etc.

6. Pollution is a global problem although urban areas more polluted than country sides.
Air and water currents carry pollution.
Pesticide/chemical poison use to kill pest or unwanted living things seeps into water ways but its harm
wildlife.
Wind can pick up radioactive material that release from nuclear vector and scatter it around the world.
smoke from a factory one country drift into another country.
 coal burning power plant in Texas has spewed so much pollution into air.
There are four major types of pollution such as: air pollution, water pollution, land pollution, and also noise
pollution.

7. AIR POLLUTION
Most air pollution in not natural, it comes from burning fossil, fuels, coal,
oil and natural gases.
Cars and factories produce other common pollutants like nitrogen oxide,
sulfur dioxide, & hydrocarbon.
air pollution like nitrogen oxide and sulfur dioxide mix with moisture
they change into acids than fall back to acid rain.
Acid rain can destroy all trees, lakes and others.
In Sweden acid rain created thousands of dead lakes where fish no longer
live.

8. WATER POLLUTION
Polluted water looks muddy, smelly beds, and has garbage floating in it.
Some polluted water looks clean, but filled with harmful chemicals, you
cant see or smell.
Polluted water unsafe for drinking water & swimming.
United nation estimates that 4000 children die everyday from drinking
dirty water.
Some polluted water harms indirectly, they get sick because fish lives in
polluted water that unsafe.
Chemicals and oils from factories dumped or seep into water ways,
which create toxic environment for aquatic life.
Also create a fertile environment (blue-green algae).
More than 2 million animals died as result of dirty water.
Many cities have poor sewage systems &sewage plant treatments.
A major source of water pollution is fertilizer used in agriculture.

9. LAND POLLUTION
Earth’s surface made up of 29% of land.
Deforestation, urbanization and agriculture are the main reasons for
land pollution.
Land pollution effects human beings, plant as well as animals.
Harmful agricultural practices like crop burning cause land pollution.
Trash is another form of pollution around worlds like papers, cans,
glass jars, plastic products and junked cars etc.
Animals can die if they mistakenly eat plastics.

10. NOISE POLLUTION
Noise pollution affects health and behavior of humans as well as animals
both, it damages psychological health of both.
Sound becomes undesirable when it disturbs normal activities such as
working, sleeping, and during conversations.
In cities sound of buses, cars, trucks, and other vehicles, start producing
sound especially during traffic jams, it mentally and physically disturbs
the peoples on roads.
Those peoples who admitted in hospitals suffer from serious brain related
problems due to noise.
Noise pollution can cause temporary or permanent damages to our ears.
