2. Introduction
Did you know that the water we use today is the same water the dinosaurs used?
We cannot create new water. For millions of years, the water we have has been
used again and again. We have been able to do this because there are natural cycles
that clean the water each time we use it.
People are polluting our water. Businesses and cities dump chemicals and waste
products into our rivers, lakes and oceans. People throw trash–furniture, garbage,
old tires, cars, old fencing, anything they can think of–into the water. People also
pollute the water by accident, by allowing their cars to leak oil and gas onto the
ground. That oil and gas eventually washes into the water during rain storms and
when people clean their driveways off with water.
Effect of Water Pollution
Estimating suggest the nearly 1.5 billion people lack safe drinking water and that at
least 5 million deaths per year can be caused to waterborne diseases. With over 70
% of the world covered by oceans, many people have dumped waste in these
bodies of water. Raw sewage, garbage and oil spills is overwhelmed with pollution
in the waters.Sometimes beaches are closed often because of high amounts of
bacteria from sewage disposal and wildlife is beginning to suffer and die.

3. Sources of Water Pollution
There are direct and indirect sources of water pollution.Direct sources include the
garbage from factories, refineries, waste and plants.
Indirect sources include contaminants that enter the water supply from soils/
groundwater systems and from atmosphere , rain water. Soils and groundwater
contain a lot of industrial waste.
How does it affect us!
Water Pollution affects people because the same water that is polluted by those
factories, things from our house or people dumping things into the water is the
same water that we drink and use.
Scientists have proven that you can get diseases from such drinking water. Kids
sometimes swallow water from pools and lakes and if the water is polluted they
can get very ill and die.
Three Sides To The Story
Not all people think water pollution is worth doing something about. Some
people think that water pollution will go away on its own.
Some people think that water pollution is something to care about and want
to do something to stop it.
Some people don’t know what to think. They think that what the first group
is talking about is true but also the second group.

4. How much water do we use
What will happen
It will turn into people thinking that water pollution is fine. Then a lot of people
will start to die and then they’ll start to care.
The water will turn even grosser than it already is and people won’t be allowed to
go swimming anymore because of the illnesses.

5. How Can We Best Deal with Water Pollution
Streams can cleanse themselves of many pollutants if we do not
overload them.
Preventing water pollution usually works better and costs less than
trying to clean it up.
Reducing water pollution requires preventing it, working with nature
in treating sewage, cutting resource use and waste, reducing poverty,
and slowing population growth.
