It is up to us – all of us – to make changes in our lifestyle, that will slow down and hopefully stop these problems. Slide 3: THE MAJOR CAUSES ARE AS FOLLOWS- Slide 4: POLLUTI0N Slide 5: POLLUTION AND SOLUTION *Air pollution and solutions *Water pollution and solutions *Land pollution and solutions Slide 6: WATER POLLUTION Slide 7: WATER POLLUTION Organic pollution Agricultural pollution Runoff, toxic waste Thermal pollution. EUTROPHICATION.. Undue enrichment of a lake, river etc. with nutrients, resulting in growth of organisms and depletion of oxygen level in water. Slide 8: More is water pollution more is the pressure on the environment. Waste that come from the sewage plant encourage the growth of algae. Overgrowth of algae water soon becomes algae ridden and oxygen become depleted. COSEQUENCES : COSEQUENCES Harms our health Destroy the ecosystem Endanger the livelihood of the fishermen Affect the tourism SOLUTION OF WATER POLLUTION : SOLUTION OF WATER POLLUTION Legislation- Water Pollution Control Regulations Water Control zones The livestock waste control scheme Construction- of sewage collection systems and sewage treatment works Monitoring- Monitoring station close supervision OUR DUTIES : OUR DUTIES 1. Lesser the use of water. 2. Use less cleansers when washing. 3. Never throw rubbish into the sea or river. Slide 12: litter Illegal dumping of domestic waste Agricultural activities Industry development Construction waste LAND POLLUTION REASONS- Slide 13: Disturb the living of the habitants Harm the human health Bring adverse effect to tourism CONSEQUENSES Slide 14: Landfills Recycling of materials Education to the public FOR A CITIZEN- 1. Reuse scrap paper and plastic bag 2. Use recycled material SOLUTION- Slide 15: Traffic Factories Air conditioner Incinerators Power stations AIR POLLUTION Slide 16: Low level of visibility Acid Rain Smog Green house effect, Global warming Respiratory sickness CONSEQUENSES Slide 17: Government 1. Planning relocate stationary sources of air pollution away from the main urban areas 2. Legislation Air Pollution Control Regulations Air Quality Control Zones 3. Monitoring and detection stations to measure the amount of the air pollutants 4. Advice and education Free advice Environmental education to citizens Air Pollution Index (API) are provided to public Citizen 1. Improve in engineering 2. Report polluting vehicles to the police 3. Cut down the use of electricity 4.Use mass public transport SOLUTION- Slide 18: DEFORESTATION What are the Causes of Deforestation? The destruction of the forests is occurring due to various reasons, one of the main reasons being the short term economic benefits. Given below are some more common causes of deforestation: Used for Urban and Construction Purposes: The cutting down of trees for lumber that is used for building materials, furniture, and paper products. Forests are also cleared in order to accommodate expanding urban areas. To Grow Crops: Forests are also cut down in order to clear land for growing crops. To Create Grazing Land: Forests are cut down in order create land for grazing cattle. Used for Fuel: Trees are cut down in developing countries to be used as firewood or turned into charcoal, which are used for cooking and heating purposes Slide 19: Erosion of Soil: When forest areas are cleared, it results in exposing the soil to the sun, making it very dry and eventually, infertile, due to volatile nutrients such as nitrogen being lost. In addition, when there is rainfall, it washes away the rest of the nutrients, which flow with the rainwater into waterways. Because of this, merely replanting trees may not help in solving the problems caused by deforestation, for by the time the trees mature, the soil will be totally devoid of essential nutrients. Ultimately, cultivation in this land will also become impossible, resulting in the land becoming useless. Large tracts of land will be rendered permanently impoverished due to soil erosion. Disruption of the Water Cycle: Trees contribute in a large way in maintaining the water cycle. They draw up water via their roots, which is then released into the atmosphere. A large part of the water that circulates in the ecosystem of rainforests, for instance, remains inside the plants. When these trees are cut down it results in the climate getting drier in that area. Loss of Biodiversity: The unique biodiversity of various geographical areas is being lost on a scale that is quite unprecedented. Even though tropical rainforests make up just 6 percent of the surface area of the Earth, about 80-90 percent of the entire species of the world exist here. Due to massive deforestation, about 50 to 100 species of animals are being lost each day. The outcome of which is the extinction of animals and plants on a massive scale. Flooding and Drought: One of the vital functions of forests is to absorb and store great amounts of water quickly when there are heavy rains. When forests are cut down, this regulation of the flow of water is disrupted, which leads to alternating periods of flood and then drought in the affected area. . EFFECTS OF DEFORESTATION Slide 20: CONSEQUENCES OF DEFORESTATION Rainforests around the world still continue to fall. Does it really make a difference? Why should anyone care if some plants, animals, mushrooms, and microorganisms perish? Rainforests are often hot and humid, difficult to reach, insect-ridden, and have elusive wildlife. Slide 21: SOLUTION OF DEFORESTATION *REFORESTATION *LEGISLATION *WILDLIFE SANTUARY *INICIATIVE TO CORPORATES *COMMERCIAL FOREST CORPRATION *WATER MANAGEMENT Slide 22: GLOBAL WARMING Increase of the earth's temperature by a few degrees resulting in an increase in the volume of water which contributes to a rise in sea-level Refers to the natural warming and cooling trends that the earth has experienced all through its history. Slide 23: What are the Possible Causes? *Pollution *Agriculture *Fossil Fuels -Burning of coal *Transportation vehicles *Greenhouse gasses -Water vapor -Carbon dioxide -Methane -Nitrous Oxide *Natural greenhouse effect *Enhanced greenhouse effect Slide 24: Solar energy Warming of the Earth’s core CO2 levels increasing because warmer oceans release more CO2 In turn global warming could lead to global cooling Other Possible Causes? Are Humans Causing the Climate to Change? : 98% of greenhouse gas emissions are natural 2% are from man-made sources Warmed slightly in the last 100 years, 70% of warming occurred prior to 1940 Are Humans Causing the Climate to Change? Slide 26: Glaciers Greenland Rising Sea Level Polar Bears What and Where are the Signs? Slide 27: Drought and wildfires Intense rainstorms Flooding of costal areas Health effects Hurricanes Is there Cause for Concern? WILDFIRE Slide 28: Drive efficient vehicle Drive less Buy energy efficient appliances Use compact florescent light bulbs (CFL) Weatherize your home Choose renewable sources of energy PLANT MORE AND MORE TREES What We Can Do? Slide 29: Unplug unused equipments Turn off the lights Set computers to sleep when not in use Take control of temperature Use appliances efficiently Energy Saving Habits Slide 30: I hope you’ve enjoyed reading and thinking about these slides to “Save the Earth”. And I hope you might try to do one or two(or all!) of these…..Starting from today!!! THANKING YOU… You do not have the permission to view this presentation.
