Introduction
We all create pollution therefore everyone can make a difference to reduce pollution. Although it may seem like it is difficult to stop pollution, there are lots of things that can be done every day to reduce or eliminate pollution altogether
?What is Pollution
ما هو التلوث؟
,Every day we pour or release harmful substances such as poisonous gases
chemicals and garbage into our environment. These harmful substances that
end up damaging the environment, are called pollution. Most pollution
comes from factories and transportation but as you will see we all
.contribute to it in many different ways

it is released into the environment it becomes pollution. When most
people think of waste they think of garbage or trash that is littered all
over the land. This type of waste is the one that most people are
familiar with and it is commonly called solid waste. But solid waste
pollution is not the only type of pollution out there. Can you think of

pollution and even noise pollution. As you will see, if not handled
properly, pollution can and has contaminated our air, water, soil and

Air Pollution
تلوث الهواء
Every living creature relies on clean air to survive. Air is made up of a
mixture of gases, mainly oxygen and nitrogen, with small amounts of
carbon dioxide plus water. Air has no colour or smell, except when it is
polluted. Dirty air can affect the health of humans, animals, plants and
can even damage buildings. Industry and transportation produce most of
the air pollution, releasing millions of tons of harmful substances into
.the environment each year

most of the world's energy. Unfortunately it also generates most of the
world's air pollution. That is because when we burn the fossil fuels to
produce energy we end up releasing waste in the form of toxic gases.

Carbon dioxide gases play a big role in the greenhouse effect by trapping
heat rather than allowing it to escape into space. It is not just what is
released into the air that causes problems; it is also how individual
,pollutants interact with each other, water and/or sunlight. For example
sulphur dioxide and nitrogen oxide are both dangerous when they combine
.with other substances to create problems such as smog and acid rain

,environment including plants and animals living on land and in the water
as well as damage buildings and other manmade structures such as
monuments, roads and vehicles. Acids cause so much harm because they can
burn into materials. Acid rain forms when sulphur dioxide and nitrogen
dioxide (produced by burning fuels) are released into the air. These two
gases mix with water to form a weak acid which falls as rain. The gases
that cause acid rain are released by power plants, factories and
transportation. Acid rain falls to the ground and is taken up by tree
roots, eventually causing the trees to die. The acid rain will also

Water Pollution
تلوث المياه
In addition to clean air, all animals and plants need a clean water
supply in order to survive. You may think that we have lots of water but
only a small amount of it is freshwater that we can use and we are
.polluting our water in the same way we are polluting our air

When harmful substances such as oil and chemical wastes enter the
waterways either through accidents or through being intentionally dumped,
they are soon carried away by tides or the flow of the river and are
extremely difficult to remove. As a river makes it's way to the ocean, a
number of different chemicals can enter its waters. Harmful chemicals can
enter our rivers and lakes from any number of sources. For example they
can seep out of dumpsites or pesticides and fertilizers may drain from
farmlands or they may find their way into sewage that is pumped from
local towns and cities

Land/Soil Pollution
تلوث التربه
Disposing of acids, pesticides, chemicals, radioactive waste, sewage
sludge and other types of hazardous waste on our lands has become one of
the most dangerous pollution and waste problem. Most of this hazardous
waste is sent to landfill sites or burned in incinerators which in turn
create toxic runoff and air pollution. In the past this hazardous waste
has also been buried deep underground. However, because of poor storage
methods older landfills and underground storage sites may end up leaking
.hazardous materials into surrounding soils and sometimes groundwater
This results in contaminated lands that pose a threat to people living in
.the area as well as to wildlife and the environment

should also be concerned about the amount of waste that is being disposed
of in these landfill sites. Per person, Canadians throw away more garbage
than any other country. The more garbage we produce the more resources
and space we will need to dispose of it. This is a problem because we are
running out of places to locate landfill sites. Nobody wants to live next

highest is ***- *l, glass and plastics at 34%. Finally, about 15% of the
material disposed of in dumps are food and yard waste. All of these
materials can and should be kept out of our landfills. If you add up all
these numbers, over 87% of what makes up a landfill site could have been
recycled, reused or composted. But instead we are polluting our land by

.constant rumble from cars, trucks, buses, machines, alarms and sirens
Even loud music is a form of noise pollution. Some communities are also

.Other people have to work in noisy factories
When these vehicles, horns, radios, heavy machinery, make loud and
continuing sounds they are producing noise pollution. We don't think of
noise as being able to hurt us but it does. Noise can cause damage to our
hearing and lead to other health problems, especially if you are exposed

?What is Pollution Prevention
ما هي موانع التلوث
Usually, once pollution is created it is here to stay. When we try to
clean up pollution after it has already been created, sometimes we just
end up shifting it from one place to another (i.e. from land to air or to
.(water
Therefore, instead of trying to clean up pollution or wastes after it has
been created, pollution prevention looks at ways of reducing the creation
of pollution and waste by changing the way we buy, make or discard of
things. Pollution prevention aims to identify activities or areas in
processes where waste can be avoided such as: where less toxic or less
hazardous materials can be substituted for the more toxic ones; and where
.energy, water or other raw materials can be saved or conserved
The pollution prevention approach tries to focus on reducing pollution at
.(the source (i.e. where it is first created
<img alt="" style="cursorointer;" border="0">
ointer;" border="0">Pollution costs money. In the past, industries and businesses really only
looked at the cost of treating and disposing of pollution. But pollution
.is not only expensive to treat; it also takes energy and resources (i.e
labour, time) to create it in the first place. Therefore, in the long
run, it costs less to avoid creating waste or pollutants from the start
.than trying to clean up, treat or dispose of it

Preventing WATER Pollution
منع تلوث المياه
There are a number of ways that you can help prevent water pollution
around your house, school, work or neighbourhood. Here are just some of
:the ideas
<img alt="" style="cursorointer;" border="0">
ointer;" border="0">Install "low-flow" shower heads and faucets to reduce water use *
Only run the dishwasher when it is full and use dishwasher soap that *
does not contain phosphates
Disconnect the down spout from your eaves trough if it discharges *
into a sewer system
Install a rain barrel to collect rain for watering plants and your *
.lawn. Share your rainwater with neighbours
Plant plants that can grow with low moisture content in soils and do *
not need to be watered very often
Take your car to a car wash facility rather than washing it in your *
driveway or on the street
Don't pour chemicals down the storm sewer *
Buy biodegradable or environmentally friendly soap and other cleaning *
supplies
Fix taps, faucets and pipes that are leaking *
Preventing LAND Pollution
منع تلوث التربه
!The best thing we can all do to cut down on waste is to make less of it
When we reduce the amount of waste that we produce this will reduce
amount of garbage that we have to dispose in landfills. Some ideas on
:reducing land pollution include
<img alt="" style="cursorointer;" border="0">
ointer;" border="0">Try to purchase materials that are sold in reusable containers *
Look for products that have very little packaging to throw away *
Buy biodegradable products *
Buy in bulk to reduce packaging *
.Use safer alternatives to pesticides *
!Reduce, Reuse, Recycle *
Buy organically grown fruits and vegetable. (i.e. those that are *
(grown with natural fertilizers such as composted manure or compost
Take old clothing, furniture and appliances in good working condition *
to collection depots and centres
Preventing NOISE Pollution
منع التلوث الضوضائي/الضجيج
.Reducing noise pollution is the easiest one of all
Keep the volume of music and the television down at home so you don't *
disturb other family members or neighbours
Don't slam doors *
Don't thunder up and down stairs - try to walk quietly *
At the end, pollution prevention is not difficult. Opportunities can be
found at home, when you shop at the store, when you go to school or when
you go to work. You can take steps every day to help stop pollution. Once
,you get in the habit of thinking about the pollution you are creating
.you will soon recognize more and more opportunities for preventing it
Challenge yourself to find a new way to reduce pollution each week or
improve on something you have already started, like riding your bike more
.often, or walking to school every day instead of once or twice a week
