2 ACOUSTIC POLLUTIONAcoustic pollution, also called noise pollution, is an excessive noise thatmay disrupt the activity or balance of human or animal life.CAUSESTraffic noise is the main source of noise pollution caused in urban areas.Low flying military aircrafts landing over the national parks, and other vacant areas.Plumbing, boilers, generators, air conditioners and fans create a lot of noise in the buildings.Household equipments, such as vacuum cleaners, mixers and some kitchen appliances are noisemakers of the house. EFFECTSDeafness, temporary or permanent.Noise pollution acts as a stress invigorator.People can be victims of certain diseases like blood pressure, mental illness, etc.Most plants require cool & peaceful environment to grow. Noise pollution causes poor quality of crops.Animals are susceptible to noise pollution as well. It damages the nervous system of the animals.Noise indirectly weakens the buildings, bridges and monuments.
3 SOLUTIONS 1. To restrict vehicular horns up to a certain frequency 3. Educate students, employees, drivers of all vehicles about the noise pollution in masses.4. Start off huge rallies against noise pollution6. Punish those who violate this rule by imposing fine.7. Keep factories far from cities areas.
4 LIGHT POLLUTION CAUSES EFFECTS Light pollution is caused by Light pollution, also known as luminous pollution is any illuminationof the night sky caused by obtrusive artificial light. The problem began with the light bulb an invention developed out of necessity about 125 years ago.Light pollution is caused byuncontrolled emissions andreflections.Some causes of this pollution:Light trespass Over-illuminationGlareLight clutterSkyglowNeurological disorders such as insomnia, migraine and depression.It interferes with the biological cycle of nocturnal animals, altering their feeding, migration and reproduction activities.Light pollution causes waste of energy and puts a strain on the already depleting resources on earth.CAUSESEFFECTS
5 ACOUSTIC AND LIGHT POLLUTION Some species like thebelugas or the dolphinsmight be affected whenmigrating by acousticpollution produced by allthe vehicles from above
6 SOLUTIONS Use lower wattage light bulbs. Replace used lights. Don't use any lights when you don't specifically need them.Buy fixtures that fully encase bulbs so all the light is shining down where it's actually needed, not shooting off in every direction.LOW VOLTAGE BULBS
7 WATER POLLUTION It´s the contamination of water bodies. It occurs when pollutants are discharged into water bodies without adequate treatment to remove harmful compounds.CAUSESThe industrial processes.Urban waste.Oil spills,Modern agricultureThe emission of pollutant gases.EFFECTSThe death of aquatic animalsDisruption of food chains,DeseasesDestruction of ecosystems.
8 OVEREXPLOTATION - CAUSES Occurs if a water resources are mined or extracted at a rate that exceeds the recharge rate.- CAUSES-The excessive use of water in the agricultural sector, the industrial sector and is also caused by the urban use of water.-The hydraulics directed at massive catchment or regularization of water.-EFFECTS- The scarcity of water, changes in climate and soil, floods, droughts and desertifications.
9 Water Overexplotation SOLUTIONSWater OverexplotationWater PollutionInside The Home:Conserve water whenever possible.Do not deposit any harmful chemicals or medications down the drain.Recycle and dispose household waste properly.Outside The Home:Refrain from using fertilizers or pesticides on lawns or gardens.Preserve our forest, which are natural water purifiers, by reducing paper use and by supporting reforestation.Don't deposit any waste or litter in any water system.Keep all boats and water crafts well maintained.The utilization of the wastewater, through debugging techniques such as ozonation or chlorination among others, for reuse in certain types of irrigation.Rationalize it’s use.Stop the waste.Take it to places where it is still lacking.Collect rainwater and make it drinkable.
10 DEFORESTATIONIt´s the removal of forest, normally due to human activities. The main causes and effects are:CausesEffectsExplotation of wood for furniture, paper, etc.Loss of biodiversityExplotation os minerals and resources under the forestErosion of soilExpansion of urban areas and transport infrastructuresLess absorption of carbon dioxide and less production of oxygenClearing land for agricultural useLoss of the way of life of natives
12 SOLUTIONSUse different agricultural practices: Forest are not cut for free space for crops.Curb the felling of trees: By employing a series of rules and laws to govern it.Reforestation: Try to restocking of existing forests and woodlands that have been depleted through deforestation.Creation of wildlife santuaries or reserves: Where animals cannot be caught or huntedReduce greenhouse effects: To prevent temperatures from rising
13 LOSS OF BIODIVERSITYBiodiversity refers to the number of different species of living things that inhabitat a specific area.-CAUSESGlobal climate change-The introduction ofgenetically modified especies.-Pollution and contaminations-Habitat loss and destruction-Alteration in ecosystem compositioThe camalote and transgenic corn
14 SOLUTIONS-Protecting Areas: Creating protected areas where human activity is limited or none.-Preventing Species Introduction.-Slowing or erradicate Climate Change.-Promoting Sustainability: Sustainable agriculture is much better for the environment than grazing and cropping,
15 AIR POLLUTIONAir pollution is the contamination of air at its different levels. There are several problems:-Smog-Acid rain-The hole in the ozone layerWe are going to focuse on acid rain
16 ACID RAINAcid rain is one of the consequences of air pollution. When any type of fuel is burnt, various chemicals are released into the air. The factory´s smoke, also have a lot of invisible gases highly harmfull to our environment.CAUSESIt´s formed by sulfur oxide plusoxygen : S+O2 = SO2Much of SO2 (sulfur dioxide)emitted into the atmosphere comesfrom natural emission is producedby volcanic eruptions.However, a source of SO2 is mainlyfrom general industries.EFFECTSThe destruction of forestsdue to the effect acid raincauses in the leaves of thetrees.The contamination of sensitive forest soils making them infertile.The contamination of lakes and rivers.
18 SOLUTIONS Reducing the maximum sulfur level in different fuels. Conversion to gas vehicles and government business enterprises.Do not add many chemicals on crops.Extension of electric transportation system.Follow kyoto protocol
19 DESSERTIFICATIONDesertification is a type of land degradation in which a relatively dry land region becomes increasingly arid, typically losing its bodies of water as well as vegetation and wildlifeCAUSESDroughtsClimatic shiftsGrowing populations that increase pressure on fragile land resourcesRemoval of vegetationEFFECTSSoil becomes less usableVegetation lossNo crops can be grown
20 CONCLUSIONWe are destroying a wonderful planet. And the choice to stop this madness is in our hands so little by little we have to start to create a better world for us and for the comming generations.
