Environment Pollution

  1. 1. Heal the world By:Manish Aggarwall
  2. 2. Introduction There are only estimate 2,500 tigers in the world Global warming Global Warming measurable increases in the average temperature of Earth’s atmosphere, oceans, and landmasses. Scientists believe Earth is currently facing a period of rapid warming brought on by rising levels of heat- trapping gases, known as greenhouse gases, in the atmosphere.
  3. 3. These are the one Wildlife and earth Click to watch video Spread of new species Organisms can be carried around the world in holds of ships, stuck inside the tread of cars trees, in crop such as bananas that where shipped from country to country, and by other means. in the wile to survive they adapt there self and a new species is born.
  4. 4. Save from these and using these • Extreme risk of extinction Critically • Giant ibis What have you done?? endangered • Does not survive any where • Falkland wolf, Martinique Click to Extinct parrot watch video • High risk of extinction in the wild Vulnerable • Cheetah Survey For survey such as those such as those as those carried out for the red list (up, right) be valid and useful, they have to carried out scientifically. Observations and record must be precise and accurate. Everything about the survey must be kept exactly the same every time observation are repeated, change in the number of individuals counted.
  5. 5. Why is conservation important? Nothing in natural world in constant. However, Tigers estimate that The needs of an increasing human population there are fewer than for food and space in huge effect on habitats 2,500 left in world. and on their plant and animals. Spices are being extinct everyday. Conservation is important because it aims to protect the natural world, to prevent species going extinct as a result of man’s activities and to prevent further habitat damage. Conditions for life All living things have basic requirement in order to survive. In the case of the polar bears shown right, the arctic , with an adequate food supply. They must be safe from predators and able reproduce. If all of these are present they will survive.
  6. 6. Protecting areas One of the one main the conservationists seek Elephants are killed for to protect areas. These are areas in which all of their tusk(now banned but still are killed) organisms in an area - whether the habitat is desert, woodland, wetland, or a coral reef in the sea- are protected from hunting, deforestation and other damage. Science or tourism Some people think it is most important to protect the scenery, particular as that is what the general is interesting in. The beauty of protected areas brings tourism and with in money. On the other hand, many conservationists argue that the entire ecosystem is what matter most, less attractive species .
  7. 7. Into the future Egg donor Scientists remove an egg cell from a female sheep and extract the nucleus containing genetic material from the egg cell to form an enucleated cell. Genetic donor At the same time, scientists collect a cell containing a nucleus with genetic material from a second sheep. The nucleus from the donor cell is removed. Enucleated cell and nuclear fusion Scientists use electricity to fuse the enucleated cell from the egg donor with the nucleus from the genetic donor. Embryo development The fused egg cell and nucleus divides and grows to form a sheep embryo. Embryo implantation Scientists implant the sheep embryo into the uterus of a third sheep, which acts as a surrogate mother. Birth of clone The surrogate mother goes through a normal pregnancy and gives birth to a sheep that is a clone of the genetic donor. Cloning
  8. 8. Case study - whale Fact file There are two groups of whales: Toothed Caught for their blubber and bones and baleen. Blue whales are largest creature ever to have lived on earth. If whales swim too close to the shore they Click to watch video may be stranded to beach. In some places, the blue whale populations are now growing in size. Climate change may mean many blue whales will die lack of food. Continued threat Between 1904 and 1967, more than 350,000blue whales were killed in the southern hemisphere. In 1967,they were given legal protection, not all countries with this.
  9. 9. Case study- rain forest . Half of all animals and fact file plant species in the world live in Rainforest once covered around rainforests 14% of the earth’s land surface. Today they cover just 6% and if it continued it will disappear in 40 years. Rainforest plant have been in traditionally medicines for 100 of years . Economic assistance from rich countries can help to save rainforests areas. 500 years ago there were around 10 million Indians living in Amazonian rainforest. Now there are less Trail of destruction than 200,000. Trees are cut down for their wood, such as mahogany, which is valuable. The process of harvesting the wood destroys everything else around it too, as habitat vanish, soil is lost due to erosion and air and water are polluted.
  10. 10. War
  11. 11. Caution !!! War, in international law, armed conflict between two or more governments or Armored Soldiers states. When such conflicts assume global in Battle proportions, they are known as world wars. War between different parts or factions of the same nation is called civil war. Click on image to watch A rebellion is not legally considered a war; to entitle the armed forces of the rebels to the rights and privileges of belligerents, the government they serve must be organized so as to be in a position to meet the duties resting on belligerents, that is, they must have the power to maintain law and order within the regions occupied by them and to carry on war on a large scale by land, sea, or air. International International hostilities sometimes continue for long periods of time without being acknowledged as wars. The Korean War was regarded by the U.S. government as a police action. Conflicts or wars in which major powers purposely refrain from employing all their armed strength are often known as limited wars. Short of peace, such limited wars are now recognized as a preferable alternative to the specter of nuclear war.International wars are generally terminated by treaty, and civil wars by a peace proclamation. The usages, customs, and treaties of nations have formed a system of laws of war.
  12. 12. Conclusion- death or peace Death and sacrifice for Smart bomb brave and peace for them who understand it. World war 1 World War I, military conflict, from August 1914 to November 1918, that involved many of the countries of Europe as well as the United States and other nations throughout the world. World War I was one of the most violent and destructive wars in European history. Of the 65 million men who were mobilized, more than 10 million were killed and more than 20 million wounded. The term World War I did not come into general use until a second worldwide conflict broke out in 1939 (see World War II). Before that year, the war was known as the Great War or the World War.

  14. 14. Reason What had become of them Our selfishness to our kind, Comfort and so after Acid rain (gift from on !!! humanity) Global Warming or Climate Change, measurable increases in the average temperature of Earth’s atmosphere, oceans, and landmasses. Scientists believe Earth is currently facing a period of rapid warming brought on by rising levels of heat-trapping gases, known as greenhouse gases, in the atmosphere. Greenhouse Effect Greenhouse Effect, the capacity of certain gases in the atmosphere to trap heat emitted from Earth’s surface, thereby insulating and warming the planet. Without the thermal blanketing of the natural greenhouse effect, Earth’s climate would be about 33 C (about 59 F) cooler—too cold for most living organisms to survive.
  15. 15. Greenhouse started 200 years ago Result increase in Pollution in our temp breathing CO2 absorb by trees Now cannot because Deforestation How global warming???
  16. 16. Pollution Pollution, contamination of Earth’s environment with materials that interfere with human health, the quality of life, or the natural functioning of ecosystems (living organisms and their physical surroundings). Although some environmental pollution is a result of natural causes such as volcanic eruptions, most is caused by human activities.
  17. 17. How to heal the world??? Use the RRR (Recycle reuse and you know) formula . Make your caste humanity not Muslim, Indians, etc. Instead of deforestation use you common sense (reforestation). Distribute your book who effort them. Read red data book and watch channels like discovery, news, etc. Save your fuel and while save your time, money and start of something big. If you see them as animal we were even some day those or we are now worst. Teach them the way or describe them the way as you teach . World is not that big you think the way to heal maybe in meters or even in centimes sometimes even less.
