4 What type of pollution? 4

5 What type of pollution? 5

6 Effects of Air Pollution Health problems Damage to the environment Damage to property Thinning of the protective ozone layer of the atmosphere 6

7 How A cloud of smoke from the exhaust of a vehicle Smoke from a factory chimney Eruption of a volcano Cigarette smoke Burning leaves Why Increasing traffic Growing cities Rapid economic development Industrialization Apathetic people 7

8 Effects of Water Pollution Devastating to people and animals, fish, and birds. Unsuitable for drinking, recreation, agriculture, and industry. Destroys water life. 8

9 Water Pollution How Toxic substances dissolve in water or gets deposited on the bed. Toxic substances enter lakes, rivers, streams, etc. Pollutants go down into the ground. Sources City sewage Industrial waste Agricultural run-off 9

10 Solid Waste Types of waste Household waste Industrial waste Biomedical or hospital waste Why Population increases Increased plastics products Changes in lifestyle Landfills not well equipped to protect against contamination 10

11 Air Pollution Solutions Encourage your family to walk more Take the school bus Reduce the amount of spray bottles Do not burn leaves in your yard- put them in a compost Keep your family cars in tune Put catalytic converters on cars Share your room with others when the air conditioner is on Take care of your trees 11

12 Water Solutions Keep lakes clean Take your used motor oil to a drop off place Use latex paint instead of oil and rinse your brushes in the sink rather than the yard Fill a spray bottle with soapy water instead of bug spray Plant trees to prevent soil erosion Keep litter, pet waste, leaves, and grass clippings out of gutters and storm drains. 12

13 Solid Waste Solutions Carry your own bag with you when you go shopping Say no to all plastic bags as often as possible Reduce the use of paper bags also Dig a compost pit in your garden and put all the biodegradables in it When you go out do not throw paper and other wrappings or even leftover food here and there-put it in the garbage 13

14 Read the two scenarios below. Write down important concept words in your notes. Then, give definitions to the words preservation and conservation (which scenario discusses preservation? Conservation?). 1. When I visited the Red Frog Island in Panama a few years ago, the tour guide informed me about the how the Red Frogs were becoming endangered in that area due to increase in tourism. In order to restore the balance in their ecosystem, the Panamanian government set aside a part of the land that was off-limits to the tourists. This area was to remain untouched and left-alone, so that the organisms can live in their natural habitat unaffected by humans. 2. The earth systems students have been learning about renewable and nonrenewable resources in their Earth Science class. They learned that nonrenewable resources do not get replaced fast, so they are in danger of running out if the humans keep using it up faster than it can be made. In order to make the resources last as long as possible, the students decide to practice the three R s (reduce, reuse, recycle) in their everyday lives to effectively use as many resources as possible.

15 INTRODUTION Conservation is an ethic of resource use, allocation, and protection. Its primary focus is upon maintaining the health of the natural world: its, fisheries, habitats, and biological diversity. Secondary focus is on materials conservation and energy conservation, which are seen as important to protect the natural world. Those who follow the conservation ethic and, especially, those who advocate or work toward conservation goals are termed conservationists. I think the environment should be put in the category of our national security. Defense of our resources is just as important as defense abroad. Otherwise what is there to defend? ~Robert Redford, Yosemite National Park dedication, 1985

16 TYPES OF CONSERVATION Renewable Energy conservation Non-Renewable Energy conservation Water conservation Plant conservation Soil conversation Mineral resources conversation The types of conservation can be many or few, depending on the focus of the individual or program that is aimed at conserving the Earth's resources. The two types that are considered to be of the greatest are water and energy conservation.

17 The 3 R s Find your own ways to make less trash, and help others to learn how to Reduce, Reuse, and Recycle.

18 HOW TO CONSERVE WATER Turn off tap while cleaning your teeth, shaving or washing your face. You can waste can up to 9 liters a minute by just letting the water pour down the sink. Take a short shower rather than a bath could save you up to 400 liters a week. If you do have baths, just half fill them. Only use the washing machine and the dishwasher when you can put on a full load. It wastes both water and energy to run only a half full machine

19 How To Conserve : You can directly contribute by- Promote Recycling of papers. It takes 10 times LESS ENERGY to produce paper from used one. By switching off lights when not required. By using cloth/jute bags instead of plastic bags. Using both side of paper. Using refills instead of buying a new pen. By growing plants DON T waste food

20 Soil conservation Soil conservation is a set of management strategies for prevention of soil being eroded from the earth s surface or becoming chemically altered by overuse, acidification, salinization or other chemical soil contamination. If you see your soil eroding, protect it with grass or plants.

21 Energy conservation Energy conservation refers to efforts made to reduce energy consumption, and to preserve it for future generations. Energy conservation can be achieved through increased efficient energy use, in conjunction with decreased energy consumption and/or reduced consumption from conventional energy sources. There are two type of resources:- Renewable Resources Non Renewable Resources

22 Activity You want to start an anti-pollution campaign, make an informational poster making the public aware of the three types of pollutions 1. Start with an anti pollution catchy phrase (ex. Give a hoot, don t pollute) 2. Include the causes, the consequences, and solutions of the three types of pollutions 3. Include drawings 4. Must color, no pencil!
