- 1.Pollution & Conservation
2. Pollution & ConservationWhat is pollution?Any substance in water, soil, or air that degrade thenatural quality of the environment, offend the sensesof sight, taste, or smell, or cause a health hazardWhat is Conservation?To conserve something means to protect it and keep it inhealthy condition. 3. In Our Country The BahamasWe have very important resources which are We have many important resources which are being affected by Pollution Ground water Surface water Air Quality Coral Reefs Sea Grasses Mangroves 4. Ground Water All fresh water available to the Bahamas is from rainfall. Ourisland Grand Bahama, receives an average of 59 inches ofrainfall every year 5. Surface Water Surface water is the water found above ground. 6. Air Quality 7. Coral Reefs Habitat for importantfish such as groupers,yellow tail snappers,grunts, barracuda. A barrier againstinland flooding fromstorms and tidal waves. Attraction for visitors 8. Seagrasses Provide food for marine animals like conch, turtles and sea urchins.Seagrasses are animportant part of thefood chain. 9. Mangroves/Wetlands Provide a safe nursery or habitat for many animals such as birds, fish and crustaceans. 10. Pollution Concerns Air Pollution Land PollutionWater Pollution 11. Air Pollution Causes: Fumes and Smoke from vehicles, power plants, open burning, industrial activity and daily use of aerosols. 12. Affects of Air PollutionDepletion of the Ozone LayerOzone is a pale blue molecule of gasthat contains 3 atoms ofoxygen and is denoted as O3. 13. Ozone layer continued 14. TROPOSPHERIC OZONE = Bad Ozone This ozone is a harmfulpollutant that damageslung tissue and plants. It is formed whenpollutants from carexhaust fumes andindustrial emissionsreact chemically in thepresence of sunlight. It is a major componentof smog. 15. The Ozone Hole and CFCsWhen released into the atmosphere, man-made chemicals such as chlorofluorocarbons or CFCs become trapped inside clouds.CFCs destroy stratospheric ozone,thereby creating the annual holein the ozone layer. 16. The effect of Ozone layer depletion Increased incidences of skincancer, Increased eye damage, stunted plant growth, Damage to building materialssuch as paints and Disruption of marine life 17. Disruption of Marine Ecosystems Increased UV exposure due to the Antarctic Ozone Holeharms phytoplankton (microscopic marine plants). Phytoplankton forms the foundation of the marine foodchain. 18. CFC Consumption in The Bahamas In the Bahamas CFC-12(Freon or R-12) is themost commonly usedman-made chemical thatbreaks down the ozonelayer. CFC-12 is often used in:1. Aerosol cans (hairsprays, paints, deodorants)2. Refrigerators3. Air-conditioningunits in cars made before1995 19. Land Pollution 20. Pollution due to various activities 21. What happens next?1. As rainwater filters through the ground, it will pick up contaminants from the surface or in the surrounding soil.2. The water may dissolve the contaminants or simply carry it in to the fresh water aquifer.3. Some contaminants can be transported far distances from their source. Groundwater travels very slowly; therefore, little dilution or dispersion of the contaminant usually occurs.4. The contaminant forms a concentrated plume that follows the groundwater flow path.5. The insecticide may kill insects but also harm other animals. 22. Eutrophication (Too much Food) 23. Pine Ridge Landfill 24. Ground Water Pollution 25. Ground Water Pollution 26. Sewage pollution to Surface Waters Sewage in the water results in diseases like typhoid and cholera. These are caused by a bacteria when it gets into the human intestine. 27. The faeces passed by people suffering fromthese diseases will contain harmful bacteria. Ifthis bacteria gets into the drinking water, theymay spread the disease to hundreds of otherpersons. For this reason, untreated sewagemust never be emptied in canals, rivers etc. 28. Oil Pollution to Surface waters Kills sea birds Create a slick or layer overthe water if large enoughcan limit oxygen in thewater. Can cause death ofwhales. 29. The chain reaction leading toSeafood Poisoning from metals 30. What can be done? Remember the 3 Rs: Reduce, Re-use, and Recycle every day. Pick up trash. Choose non-toxic products for household use. Dont Litter - streets and storm drains empty into undergroundstreams that could lead to our beaches and oceans. 31. At all times, have a means for disposing of yourwaste when involved in activities such asbeaching, boating or even driving. Minimize use of fertilizers and pesticides onyour yard. Respect your Septic system dont pour toxicwastes and out-of-date medications down thetoilet. Do not dump oil down storm drains; recycleused motor oil. 32. Conservation Efforts The Clean Air Act of 1956. Implementation of sewage treatment facilities toremove harmful bacteria Control of Water pollution Conservation of Habitats (The Nature Conservancy,The Bahamas National Trust) Use renewable resources e.g. the sun, wind etc. Carry out Recycling Initiatives Conservation of Species (CITES) 33. Words of WisdomTreat the Earth well. It was not given toyou by your parents. It was loaned to youby your children- Kenyan proverb 34. We CAN have a clean earth! 35. Our future depends on a Pollution Free Environment 36. For more information visitwww.BahamasEcoVentures.com
