3 D Amelia Wong, Water Pollution Project

  1. 1. WHO DID THE PROJECT <ul><li>WONG YAO YIN AMELIA </li></ul><ul><li>CLASS:3D </li></ul><ul><li>INDEX:17 </li></ul>
  2. 2. INTRODUCTION OF WATER POLLUTION <ul><li>Over two thirds of Earth's surface is covered by water; less than a third is taken up by land. </li></ul><ul><li>Poorer water quality means water pollution. </li></ul>
  3. 3. Water pollution is the contamination of water by sewage, toxic chemicals, metals, oils, or other substances. It can affect such surface waters as rivers, lakes, and oceans, as well as the water beneath the earth's surface, called ground water. Chemical and oil spills can also cause devastating water pollution that kills fish, aquatic plants, water birds, shellfish, and other wildlife. What is water pollution?
  4. 4. How does water get polluted <ul><li>Do you know how our creeks and beaches get polluted? Or have you ever wondered what those holes in the sidewalk were for? </li></ul><ul><li>Water pollution can come from a lot of different places, but the number one reason that our rivers, lakes and beaches get dirty is from the water and other pollutants that flow into storm drains. Look below to find out more. </li></ul><ul><li>What is storm water pollution? Storm water is the water that runs down the street when it raining. Storm water enters holes in the gutter called storm drains. Water that flows down the street when it is not raining, like when you wash your car or water your lawn, is called urban runoff. </li></ul>
  5. 5. How water pollution came about <ul><li>After storm water and urban run off flow into the storm drain, it gets sent to the nearest creek, river, lake or ocean so our streets don’t flood. That means any pollutant on the street or in urban runoff gets carried to our waterbodies and eventually the ocean.` </li></ul><ul><li>Can you imagine swimming in all the gross stuff that on our streets? Soaps, grass clipping, trash, pet waste, pesticides and fertilizers, dirt and oil are just some of the pollutants that make our water unhealthy for people and other animals. </li></ul>
  6. 6. Diagram of how water get drained away and polluted
  7. 7. POLLUTANTS <ul><li>Leaves and </li></ul><ul><li>Grass Clippings </li></ul>Hazardous chemicals Soaps and detergents Trash and Litter Animal Waste Dirt Air pollution from cars Oil and other chemicals from cars Pesticides and Fertilizers
  8. 8. Examples of how water get polluted <ul><li>Too many leaves and grass clippings can take the oxygen out of water and suffocate the plants and animals who need oxygen to breathe. </li></ul><ul><li>The waste from our pets is very harmful to our waterbodies. Our pets' waste has dangerous bacteria that can spread diseases to plants, animals and humans that swim in dirty water. </li></ul><ul><li>Soaps and detergents, like too many leaves and grass clippings, can take oxygen out of water and suffocate plants and animals. Also, soaps and detergents eat away at the slimy mucus layer that protects fish from diseases and bacteria. </li></ul><ul><li>So all the gross-looking, bad-smelling, gray/black/brown/blue gases that come out of a cars' tailpipes floats up into the air and eventually lands on the ground or in a creek, river, lake or ocean. </li></ul>
  9. 9. <ul><li>Do not litter into waters, throw them into the bin. </li></ul><ul><li>Do not spray oil into waters,in order to kill the mosquitoes breeding in the waters. </li></ul><ul><li>Do not pour oil into the drain because the oil would go into the sea. </li></ul>How can we stop water pollution?
  10. 10. How can we stop water pollution <ul><li>If you see your car leaking oil everywhere, tell your parents it needs to get fixed. </li></ul><ul><li>Make sure to clean up after your dog or cat in your yard or when you take it out for a walk. </li></ul>
