ROLE OF YOUTH IN OZONE LAYER PROTECTION Ozone layer plays a vital role in protecting animals‚ human beings and plants from ultraviolet radiation. Ozone layer is destroyed by a group of manufactured or human made chemicals such as chlorine bromine. These chemicals are called "ozone-depleting substances". Ozone layer is destroyed by some natural’s ways and some humane made activities. A single molecule of chlorine can break apart thousands of molecules of ozone. Chlorofluorocarbons the most widely

Ozone depletion and Volatile Organic Compounds Christina Stelmach SCI/ January 20‚ 2013 Christine Snyder The atmospheric issue that I chose to write about is the Ozone layer depletion and the indoor air pollutant is Volatile Organic Compounds. I am going to talk about the cause and effect of each of these issues and also efforts to mitigate the issues. Our Earth’s Ozone layer protects all life from the sun’s harmful radiation. Due to all human activities damage has been done to our

Hole in the Ozone is a documentary film that educates its audience the relationship of ozone and chlorofluorocarbons (CFCs) and its effects to our atmosphere. Hole in the Ozone also known as Ozone Depletion or Ozone Thinning had been an issue since the 70s and 80s. Even until now‚ this has become one of our major environmental issues. It is surprising to know that the ozone performs a major part in protecting us from dangerous radiation that the sun emits to our planet‚ even though it is also part

Cfcs Cause Deterioration of the Ozone Layer The deterioration of the ozone layer ‚ caused by Cfcs‚ endangers the lives of humans ’. Cfcs have a diminishing effect on the ozone layer. Furthermore‚ the deterioration of the ozone cause an increase of Ultraviolet (UV) radiation which can have a negative effect on human skin and eyes. As a writer for newsweek‚ I have investigated the scenario and found the following information. The earth ’s atmosphere is a blanket of air that surrounds the planet

But there is a significant pending problem in the ozone layer. Each year‚ a large hole appears in it. It is not an actual hole‚ like a hole in a pocket‚ but a thinning in the layer that shows up on satellite pictures. The "hole" is located over Antarctica. It covers an area about the size of the United States. Experiments done in Antarctica show that the hole in the ozone layer appears to let in twice as much ultraviolet radiation as normal‚ according to measurements researchers made there only

OZONE-LAYER DEPLETION AND NATURAL RESOURCES INTRODUCTION Sometime ago‚ a warning endorsed by more than 1‚600 of the world’s most distinguished scientists‚ including 102 Nobel Prize winner states in part: Human being and the natural world are on collision course. Human activities inflict harsh and often irreversible damaged on the environment and critical resources. If not checked‚ many of our current practices put as serious risk the future that we wish for human society and the plant

OZONE LAYER DEPLETION AND GLOBAL WARMING OZONE LAYER DEPLETION AND GLOBAL WARMING. The ozone layer acts as a giant sunshade‚ protecting plants and animals from much of the sun’s harmful ultraviolet radiations. Ozone forms a layer in the stratosphere‚ 15-40 km above the earth surface. If the ozone in the atmosphere from the ground level to a height of 60 km could be assembled at the earth’s surface‚ it would comprise a layer of gas only about 3mm thick. Global stratospheric ozone

Proposed Ban of Ozone-Depleting Aerosol Spray Fact and Opinion Speech Review Suzie Student Course ENG101 June 25‚ 2010 Matt Copeland The speech‚ “Proposed Ban of Ozone-Depleting Aerosol Spray‚” describes a five-month study that was conducted in 1974 by a special administration task force made up of a group of scientific researchers who concerned themselves with the dispersion of fluorocarbons. These fluorocarbons were found in most aerosol cans‚ air conditioners‚ refrigerators

The Potential Effects of a Depleted Ozone Layer - Detrykowski "And God said‚ let there be light and there was light and then God saw the light‚ that it was good " ( Genesis 1: 3-4 ). Undoubtedly‚ light is good. Without light man could not survive. Light is the ultimate cosmic force in this universe allowing man to progress and flourish. In the form of heat‚ light from the sun warms the Earth. Light‚ also‚ is the single most important factor influencing the growth and development of plants

<b>The Greenhouse Effect</b> <br>The earth’s climate is predicted to change because human activities are altering the chemical composition of the atmosphere through the build up of greenhouse gases primarily carbon dioxide‚ methane‚ and nitrous oxide. <br> <br>Energy from the sun drives the earth’s weather and climate‚ and heats the earth’s surface. This causes the earth to radiate the energy back into space. Atmospheric greenhouse gases (water vapour‚ carbon dioxide‚ and other gases) trap some
