Global warming ppt
- 3. Global warming means the increase of average temperature of the earth .“Scientists are more than 95% sure that most of global warming is caused by increasing concentrations ofgreenhouse gases and other human caused activities
- 5. we are highly dependent on coal burning power plants for our personal and commercial electrical supply. But, coal burning power plants releases enormous amounts of carbon dioxide[co2] and carbon monoxide[co] into the atmosphere Hence, it causes a mass damage to the atmosphere
- 6. Trees and plants are the major cause for us to breath pure air. But, when we cut down the trees , It becomes a major cause for `Global warming`. Because, they inhale the carbon dioxide[co2] which is a dangerous substance and exhale the pure oxygen[o2].
- 7. The vehicles like cars, bikes, lorries, vans, tractors release carbon di oxide[co2] into the air. And affects our healthy environment. Refrigerators and air conditioners release CFC [Chloroflourocarbon] or [Freons] Causes global warming.
- 8. Methane is another extremely potent greenhouse gas, ranking right behind CO2. When organic matter is broken down by bacteria under oxygen-starved conditions (anaerobic decomposition) as in Dung, methane is produced., The process also takes place in the intestines of herbivorous animals. Hence, it causes global warming.
- 10. Melting of glaciers Due to global warming, the glaciers are melting. Hence, the animals like polar bears, penguins can’t find place to live.
- 11. Scientists predict an increase in sea levels worldwide due to the melting of two massive ice sheets in Antarctica and Greenland, especially on the East coast of the U.S. Hence, global warming rises the sea level. and creates tsunami.
- 12. Because of, global warming the water will evaporates and the ground water level will be decreased. And, all the living things will die without water.
- 13. Global warming not only decreasing the groundwater level, but also drying the water resources like rivers, ponds and lakes. Hence, we can’t get water from these water resources.
- 14. Due to global warming, the animals can’t protect them from high temperature of heat. Hence, it causes their death.
- 15. Reason for killer storms “Scientists discovered that global warming significantly increase the intensity of the most extreme storms”.
- 16. The sun is the earth’s primary energy source. The green house gases like co2[carbon dioxide], CH4[Methane], N2O[Nitrous oxide] are observe the heat from the sun and kept it on the atmosphere. It is called green house effect. It causes global warming and also affects the ozone layer which protects us from the UV rays. If these gases does not observe the heat from the sun, our earth will become full of glaciers and the temperature will decrease upto -18 degree Celsius.
- 17. According to recent research, there is a 90% chance that 3 billion people going hungry due to Global warming within 100 years Due to the global warming the fertile crops will become worse. Hence it affects our agriculture and also it causes farmers suicide.
- 20. Please Save the world from the monster
