Water Pollution
Introduction
How Does It Happen?
Who and How it affects our world
What is Water Pollution?
The first thing to know is what water pollution is:

Water pollution is when bodies of water are contaminated or filled with garbage or waste.
Water pollution affects plants, coral reefs in the water, animals that are living in these areas, humans and our ecosystem.
It's Hard To Get Back...
Throwing Garbage, Waste, and Toxins into the Water
We know the natural world is changing, and we can see it with our own eyes. These are some things that are causing us to see theses changes.
Sewage Catastrophe's
Sewage water goes through water treatment plants. Sometimes the waste goes into the ocean and isn't cleaned properly.

When installing a sewage pipe sometimes it is not installed properly so it can leak, and worst comes to worst it gets into to ocean.

Consider your swimming pool filled with your toilet and laundry water for a week. Now imagine having to swim in that!
Oil Spills
Oil spills are caused by mostly tankers, it's really bad because there is a lot of oil pouring into one place.

Oil cannot dissolve in water and forms a thick sludge type layer in the water.

When this happens it suffocates fish, gets stuck in the feathers of birds and stops the light from coming through for plants that need the light, like photosynthetic plants.
Underground and Tube Leakages
Animals..
Animals are stuck in the middle of our doings. Animals live, swim, drink, and clean in the water we have polluted.

Boats leave chemicals behind that automatically kills animals that swim through it. When land animals drink the polluted water, they can get really sick, and possibly die. Oil spills also harm and kill water animals.
The Economy..
Who does it Affect?
Water goes through water treatment plants, but does that really mean it's permanently clean? Once it goes back to the ocean or lake it just gets polluted again.
People throw things into the water all the time. Some people do it not caring about the effect it has, other people don't even know they are doing it. Have you ever left a water bottle on the beach thinking it wouldn't do any harm? When the tide comes up it carries all the garbage on the beach into the water.
Animals that live in the water have to live with garbage and gross chemicals surrounding them in there home. How would you like it if at the end of garbage day the garbage truck dumped all the garbage in your house and you couldn't do anything about it? That is how the animals live.
Some of the toxins that get put into the ocean hurt the plants too. Some of the chemicals and waste include: Pesticides, and fertilizers.
In the water, there are tubes running underneath the bottom of the ocean or lakes. When you are swimming you might be standing over some of these pipes.

Over a certain amount of time these pipes start to rust and wear out. Sometimes these pipes leak into the ocean and get chemicals into the ocean or lakes. They often store substances such as petroleum, that are harmful to the surrounding environment should it be in contact with it.

Throughout the world bodies of water are very quickly becoming polluted. This is happening all over the world.
Water pollution isn't a direct economic issue, but it does have an affect on the economy.

Many industries rely on a supply of fresh water, as more and more water becomes polluted, the price to purify the water becomes higher.

The fish industry is dying because of the shrinking fish population from pollution. Industries are deteriorating because a lot of industries only use fresh water for whatever their industry is and for.
How Can We Fix This?
What we can do to stop it!
-Conserve water by turning off the tap when running water is not necessary.
-Be careful about what you throw down your sink or toilet. Don’t throw paints, oils or other forms of litter down the drain.
-Don't overuse pesticides and fertilizers. This will prevent extra chemicals from running into the sewers, and near by water sources.
-Don’t throw litter into rivers, lakes or oceans.
-Help clean up any litter you see on beaches or in rivers and lakes, and put them in the recycling, or garbage.

Thank-you very much for watching! It is now our hope that you realize how important water is to us. Water is one of the things that we cannot live without, and ruining it would be ruining ourselves.

By: Emily and Jess
What we are doing isn't just harming everything around us, it's also has a harmful affect on us.

When we are swimming in the ocean or lake we are swimming in toxins and chemicals. We can digest chemicals when eating fish that have been in contact with it.
Water takes up 70% of the world, only 2.5% of the worlds water is fresh water (as in not salt water) and if we keep polluting that 2.5% of water, there will be very minimal amount of fresh water left.

Polluted drinking water is a problem for about half of the world’s population. Each year there are about 250 million cases of water-based diseases, resulting in roughly 5 to 10 million deaths.
How our actions are affecting us?
The Problem?
Thank-you!
