Environment Pollution

  1. 1. Our EnvironmentAn environment consists of all the things like the living and the non livingthings in it. It can be classified as natural environment andBuilt environment. One has to keep some points in mind while writing anenvironment essay. One can define the natural environment as somethingthat has been in existence for long and the built is the one that has beencreated by man. The natural atmosphere is being polluted due to theunnatural factors. Humans cause more pollution than the environmentalcauses like a volcanic eruption. It is the reckless and the caustic humannature that is primarily responsible for the environmental pollution. Most ofthe people are responsible for the pollution caused to the environment fortheir own personal motives. write up on Environment must essentially havethe causes that affect the ecosystem. It is very difficult for the humans toaccept any change from the environment they are born and live in. TheEnvironment built by humans has become more noteworthy than the naturalones in to days times. The primary reasons for issues like Global warmingLand degradation pollution etc are due the great dangers faced by everyoneas a result of the negligence.
  2. 2. Major Problems Faced By EnvironmentGLOBAL Pollution Air Pollution WARMING Water Pollution Noise Pollution
  3. 3. Global WarmingAn average increase inthe temperature of theatmosphere near theEarth’s surface and inthe troposphere1, whichcan contribute tochanges in globalclimate patterns.
  4. 4. Cau ses of fossil fuelsBurning(Coal/Crude oil) Power plants generate electricity Industrial processes (E.g. manufacture ofOther greenhousegases emissionaluminu cement, steel, m) Agriculture Forestry Other land uses Waste management
  5. 5. Example : Using natural gas tocookCH4 + 2O2  CO2 + 2H2O
  6. 6. Greenhouse gases in the atmosphere ↓ Some infrared radiation is trapped ↓ Greenhouse effectSerious greenhouse effect Global Warming
  7. 7. Environmental and Human Effects
  8. 8. Climate-sensitive diseases•Increase the risk of some infectiousdiseases [particularly that appear in warm areas; are spread by mosquitoes and other insects] E.g. Malaria, dengue fever, yellow fever, encephalitis•Algal blooms occur more frequently astemperatures warm (particularly inareas with polluted waters) Diseases (e.g. cholera) accompanying
  9. 9. AirQuality An increase in the concentration of ground-level ozone Damage lung tissue Harmful for those with asthma and
  10. 10. Measures on controlling the proGovernment * Set some lawsto limit theamount ofpollutantsproduced byfactories * Develop theskills of using
  11. 11. Measures on controlling the probCitizens * Reduce the use ofplastic bags asburning plasticemit CH4* Recycle theresources, e.g.plastic
  12. 12. DEFINITION OF POLLUTION•When HarmfulSubstancesContaminate theEnvironment it isCalled Pollution.•Pollution refers to thevery bad condition ofenvironment in termsof quantity and quality.
  13. 13. What is AtmosphereAtmosphere is the life blanket of Earth.It is therefore essential that we know more about the atmosphere and the ways in which it is Polluted.
  14. 14. Air PollutionCauses of Air PollutionMajor sources of Air Pollution - Industries, Automobiles and Domestic fuels -High Proportion of undesirable gases, such as sulphur dioxide and carbon monoxideEffects of Air Pollution -Human health -Animals -Plants -The atmosphere as a whole
  15. 15. Water PollutionCauses of Water Pollution•About 40% of Deaths worldwide arecaused by Water Pollution.•Water Pollution is Caused by organic andinorganic industrial wastes and affluentdischarged into rivers.•Noise also causes anxiety stress reactionand fright.Effects of Water Pollution•Diseases like Cholera•Malaria•Typhoid (spread during the rainy season )Aquatic life gets destroyed
  16. 16. Noise PollutionCauses of Noise Pollution•Traffic Noise•Air craft Noise•Noise from construction and civil engineering works.•Noise from the Industries.•Noise from other sources.Effects of Noise Pollution•Hearing Loss•High Blood Pressure•Stress•Sleep Disturbance•Colour Blindness
  17. 17. Condition Of Earth
  18. 18. MessageDear friends our earth is in very badconditions we need to save our earth for thiswe have to joint together and start avoidingplastic bags, loudspeakers and all the materialswhich cause pollution. If we start doing thisand advice peoples to do this it will help to usand to our future generation also otherwise infuture we need to carry Oxygen cylinder forsurvival………
