Green House Effect
This presentation discusses the greenhouse effect and its causes and impacts. It begins with defining a greenhouse as a structure that traps heat from sunlight and defines the greenhouse effect as the warming of the atmosphere due to heat being trapped by greenhouse gases like carbon dioxide. It then lists the main human causes of increased greenhouse gases as deforestation, increased population, burning fossil fuels, industrial emissions, CFCs, nuclear reactors, and unchecked urbanization. The document discusses how the greenhouse effect is influencing the environment through melting ice caps, rising sea levels, ecological imbalance, increased health risks, and threats to animals. It concludes by recommending actions like planting trees, reducing fuel burning, installing industrial emissions filters, abandoning CFCs, responsible urban

- 4. MEANING OF GREENHOUSE A greenhouse is a building made by glass sheet where plants are cultivated. In briefly, a greenhouse is a structure with a glass or plastic roof and glass or plastic walls. When the sun’s ray reflects on glass then the house gathers heat by radiation and the house keeps remain hot because the glass blocked the sun rays. Here is one image of a normal look green house
- 5. Green House In thistypes of house some plants are cultivated where normal temperature is not enough for cultivate plants. Here is one image of a normal look green house

- 7. MEANING OF GREENHOUSE EFFECT The greenhouse effect discovered by Joseph Fourier in 1824 and first investigated by Arrhenius in 1896. The Earth has a natural temperature control system. Certain atmospheric gases are maintain the system and are known as greenhouse gases. On average, about one third of the solar radiation that hits the earth is reflected back to space. Some is absorbed by the atmosphere but most is absorbed by the land and oceans. The Earth's surface becomes warm and as a result emits infrared radiation. The greenhouse gases trap the infrared radiation, thus warming the atmosphere.
- 8. Continue…. Naturally occurring greenhousegases include water vapors, carbon dioxide, ozone, methane and nitrous oxide, and together create a natural greenhouse effect. However, human activities are causing to increase the greenhouse gas levels in the atmosphere. Here is a simple figure which mentions total process of green house effect,
- 9. Figure which mentionsthe process of Green House Effect
- 10. Radiative Equilibrium Eachplanet must balance net incoming solar radiation with outgoing radiation, determined by its temperature by the Stefan-Boltzmann Law: Balance incoming and outgoing radiation: Net incoming radiation=Outgoing radiation
- 11. 1. Shorter, high Energy wavelengths Hitthe earths Surface 2. Incoming energy Is converted to heat 3. Longer, infrared Wavelengths hit Greenhouse gas Molecules in the atmosphere 4. Greenhouse gas Molecules in the Atmosphere emit Infrared radiation Back towards earth
- 12. MAIN CAUSES OFGREEN HOUSE EFFECT Human are mainly accused for the green house effect. We know that the enhancement of carbon dioxide in an extreme range is the main reason for green house effect. So from where the carbon dioxide is produced they are the main cause for green house effect. Here some examples are mentioned what are really responsible for producing carbon dioxide, Deforestation: Increasing of population: Burning fuel: Industrial Carbon-dioxide production: C.F.C. gas: Nuclear reactor: Inconsiderate Urbanization:
- 13. a. Deforestation :Plant destruction in a large scale is one of the main reasons for green house effect. Because trees are absorb the Carbon-dioxide and produce Oxygen gas.
- 14. b. Increasing ofpopulation : A huge number of human produced a huge Carbon-dioxide so it another reason of green house effect. Here is an example for that,
- 15. c. Burning fuel: Burningfuel like petrol, diesel, octane, coal and kerosene in a vast scale is another main reason for increasing Carbon-dioxide. That is responsible for green house effect. Here this image will make it clear,
- 16. d. Industrial Carbon- dioxideproduction: Different type of industries produced Carbon-dioxide and other harmful gases in a large scale. This picture mentioned it,
- 17. e. C.F.C. gas: Manyman maid things like refrigerators, aerosol cans, fire extinguisher chemicals produced C.F.C. gases that are most helpful for green house effect. It is like,
- 18. f. Nuclear reactor: Inmodern world nuclear reactor is used in commonly is also responsible for produced carbon-dioxide in a large scale. This is happened like this,
- 19. g. Inconsiderate Urbanization: Inconsiderateurbanization is another cause of green house effect that means some one build infrastructure with out planning. Here is an example,
- 20. HOW THE ENVIRONMENTIS INFLUENCED BY GREEN HOUSE EFFECT? Our earth is directly influenced by green house effect. For green house effect the temperature of our world is highly increasing. Extended temperature is too much harmful for every thing which are the element of our environment. Main problems are mentioned bellow,
- 21. a. Ices aremelting down: For global warming Arctic ices are melting down in a high scale. Hers is that,
- 22. b. Increasing sealevel: Some low laying areas like Asia pacific, America, Mexico, Bangladesh, Some portions of India are in a great threat of going under water for melting of ice. That is really an alarming matter for us. Here is an image which mentions the infected areas,
- 24. c. Ecological Imbalance: Plants growin suitable area and temperature so if the temperature is high then plants can’t grow and total ecological system is hampered. Here is this,
- 25. d. Human arein dangers: Health of human beings are in high mortality rate and increasing infections disease. e. Total environment pollution: For green house effect the total environment is in a high risk all elements if environment is polluted by green house effect.
- 26. f. Animals arein high threat: All types of animals are in danger for the reason of green house effect. They lost their home & food. Some are already existed for green house effect. This pictures will make it clear,
- 27. WHAT SHOULD BEDONE TO SAVE OUR ENVIRONMENT FROM GREEN HOUSE EFFECT? Though the green house effect is a massive attack to our environment and that should be stopped. First we have to think, for what it is happened and that causes must be eliminate by anyhow. a. Plant more trees : We must plant more trees where we can, in town or village.
- 28. Tree plantation maybe like that at urban place
- 29. b. Burning fuelin restriction: Vehicles should use protection kits to reduce Carbon-dioxide producing. c. Set safety filter on industrial fume exit pipe: Every industry must make their exit pipe safe by taking preventive steps soon. d. Leave C.F.C: In every place where the C.F.C is used must be stopped. Our scientist should invent some alternatives of C.F.C what is not harmful for environment.
- 30. e. Responsible urbanization: Forlive and other needs we must built road & building but not inconsiderately. We must do that with environment friendly thinking. That may be like this,
- 31. f. Make everyone environment award: Every one must be acknowledged about the environment, its importantness & what happed to it so they will try to save the environment. So by taking every type of precaution we can make our environment safe and sound thus our world will be a place for happiness and peace……..
