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

International Day for the Preservation of the Ozone Layer is celebrated. This date has been designated by the United Nations General Assembly in its resolution 49/114‚ to commemorate the signing of the Montreal Protocol on Substances that Deplete the Ozone Layer. | This commemoration around the world offers an opportunity to focus attention and action at the global‚ regional and national levels on the protection of the ozone layer. All Member States are invited to devote this special day to promotion

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

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

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

Ozone depletion describes two distinct but related phenomena observed since the late 1970s: a steady decline of about 4% per decade in the total volume of ozone in Earth’s stratosphere (the ozone layer)‚ and a much larger springtime decrease in stratospheric ozone over Earth’s polar regions. The latter phenomenon is referred to as the ozone hole. In addition to these well-known stratospheric phenomena‚ there are also springtime polar tropospheric ozone depletion events. The details of polar ozone

Depletion of the Ozone Layer * Function and location of the Ozone Layer The ozone layer is a portion of earth’s atmosphere that contains high levels of ozone. Ozone (O3) is a triatomic molecule consisting of three oxygen atoms. It is an allotrope of oxygen. Ozone is formed when oxygen molecules after absorbing ultra violet photon then converts a single O2 into two atomic oxygen radicals. The atomic radicals then combine with separate O2 molecules to create two O3 molecules. The main function

RAMI MASANGO 10 JUNE 2011 WORLD ENVIRONMENT DAY YOU ARE YOUR ENVIRONMENT! Good day colleagues. The World Environment Day is a reminder of how grateful we need to be to Mother Nature‚ which sustains all forms of life. This is the day to focus our thoughts and our energies to make collective efforts towards protecting the environment. World Environment Day was commemorated last Sunday on 5 June. It is a day that stimulates awareness of the environment and enhances political attention and

The ozone layer is an invisible layer of gas that shields us from UV radiation. UV radiation is ultraviolet radiation‚ or rays of the sun that can harm living things. One problem today is that the protective ozone layer around the earth is being destroyed (PROBLEM). (2) PARAGRAPHS 2‚ 3 & 4 (DEVELOPED FROM
