2. Water Pollution
Water pollution is a major global problem. It has been suggested that it is the leading worldwide cause of deaths and diseases, and that it accounts for the deaths of more than 14,000 people daily.
There are 3 classes of water pollutants:
Disease-causing agents-bacteria, viruses, protozoa and parasitic worms that enter sewage systems and untreated waste.
Oxygen-demanding wastes- wastes that can be decomposed by oxygen-requiring bacteria. Large populations of decomposing bacteria converts waste and depletes oxygen levels in the water. Cause s organisms in the water, such as fish, to die.
Water-Soluble Inorganic Pollutants-such as acids, salts and toxic metals. Large quantities will make water unfit to drink and will cause the death of aquatic lif

3. Water Pollution
Littering causes the death of aquatic animals because it takes too
long for the waste to degrade.
Foams take fifty years before it eventually degrade
Aluminum takes two hundred years before it totally degrade
Plastic packaging takes four hundred years before it totally degrade
Newspaper and cardboard takes two to six weeks before it finally degrades

4. Water Pollution
People who regularly consume a lot of fish will have larger levels of toxic chemicals and studies show that toxic chemical can lead to reproductive problems, cancer, and neurological disorders
The world's six billion people are appropriating 54 percent of all the accessible freshwater contained in rivers, lakes and underground aquifers.

5. Recycle!
Recycling is the process of re-forming or breaking down a waste product so that it can be used again.
The internationally recognized symbol for recycling includes three arrows moving in a triangle. Each arrow represents a different part of the recycling process, from collection to re-manufacture to resale.

6. Recycling Facts!
A used aluminum can is recycled and back on the grocery shelf as a new can, in as little as 60 days.
Recycling one aluminum can saves enough energy to run a TV for three hours -- or the equivalent of a half a gallon of gasoline.
To produce each week's Sunday newspapers, 500,000 trees must be cut down.
The average American uses seven trees a year in paper, wood, and other products made from trees. This amounts to about 2,000,000,000 trees per year!
Americans use 2,500,000 plastic bottles every hour! Most of them are thrown away!
A modern glass bottle would take 4000 years or more to decompose -- and even longer if it's in the landfill.

9. Air Pollution Bad Gases that are released into the air
Carbon monoxide- mainly released by cars and other vehicles
Nitrogen oxides- released into the air from car, trucks, and power stations
Hydrocarbons- produced when gasoline is not fully burnt
Particulates- small particles, like soot, dust and fumes caused by vehicles, factories and smoke from burning coal

10. Air Pollution inside Homes
Smoking cigarettes
Poison in the air can cause heart problems, lung cancer and other lung diseases
If a women is pregnant her baby might be smaller of become ill
Fresh Paint
The fumes from painting inside can become hazardous if not well ventilating
Burning of coal and gas
Coal and gas are sometimes used in heaters, stoves and ovens.

11. Cars and Air Pollution
Cars and trucks releases petrol(gasoline) and diesel
Petrol and diesel are bad gases and poison the air
A way to help pollution caused by vehicles is to car pool, walk, or ride a bike whenever possible
