  • The purpose of the presentation is..
    • We want people not to throw papers and plastics because the rubbish contaminates the water a lot and the animals die .
    • We want boats not to throw oil to the water, because it kills plants and wildlife.
    • We want people not to waste water.
    • We don’t want people to use pesticides in the water because they kill fish and other animals.
    • We want you, when you see a person throwing papers and plastics to the water to tell them not to throw rubbish anymore because they are contaminating the world.
    • And we also want you to explain this presentation to other persons and to become aware of this.
    • The water cycle works like this: sunlight causes water to evaporate or dry up into a gas called water vapour. It rises into the atmosphere and collects in clouds, the vapor condenses back into the water and rains down to earth to begin the cycle again.
    Water cycle
    • Factories pollute water, but they are not the biggest source of water pollution.
    • Farmers use chemicals that get into the soil and pollute ground water.
    The factories
    • When the rain mixes with gases and falls, it is acid rains and it is harmful to plants, animals and even buildings. Some pesticides also end up in the air and may travel thousands of miles before settling in stream, lakes, rivers, or the ocean.
    Acid rain
    • The boats strip oil, as a consequence the fish and the animals die. They also die because the people contaminate the water.
    Oil pollution
    • Water pollution is a problem in many countries. In the deserts the ground water can lead to serious diseases.
    • If the water we drink today is contaminated we can die.
    • The water we use today has been around since the time of the dinosaurs.
    The problem of water
    • Dripping faucets waste more water than you think as much as 20 gallons a day !!!
    • So it is important to care about the water because it is good for the life and wildlife.
    Waste water
  • Different water
  • Before and now In years around the 90’s The water was not polluted. Now the water is so contaminated. 90… 2010
    • The good news is that the Earth has its own way of cleaning up dirty water. It is the wetland way.
    • Wetlands are places that have shallow water or are spongy at least some of the time. Marshes, swamps, tidal flats, prairie photoles, and bogs are types of wetlands.
    The wetland way
    • The conclusion is that we are responsable for the contamination of water.
