Resume Career Goals Examples - Chlorofluorocarbons or CFCs are the main cause of ozone layer depletion. These are released by solvents, spray aerosols, refrigerators, air-conditioners, etc. The molecules of chlorofluorocarbons in the stratosphere are broken down by the ultraviolet radiations and release chlorine atoms. These atoms react with ozone and destroy it. While naturally occurring chlorine has the same effect on the ozone layer, it has a shorter life span in the atmosphere. Of all of the causes of ozone depletion, the release of CFCs is thought to. The main cause of ozone depletion and the ozone hole is manufactured chemicals, especially manufactured halocarbon refrigerants, solvents, propellants, and foam- blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons). Since the early 's, scientists observed reduction in stratospheric ozone and it was found more prominent in Polar Regions. Essay on Mobile Phones
An Analysis of The Ones Who Walk Away from Omelas by Ursula K. Le Guin - Chlorofluorocarbons or CFCs are the main cause of ozone layer depletion. These are released by solvents, spray aerosols, refrigerators, air-conditioners, etc. The molecules of chlorofluorocarbons. The ozone layer is being damaged by pollutants in the air that are mostly man-made, such as chlorine and bromine. The ozone damage occurs in the stratosphere and troposphere. The lower pollution in the troposphere has many of the same causes as the upper destruction, but causes more visible and health-related issues than the stratosphere damage. Ozone depletion is primarily caused by human activities. The main effect of ozone depletion is an increase in UV-B rays reaching the earth's surface. Causes: chlorofluorocarbon (CFCs), halons, and other compounds deplete the ozone layer. These chemicals are found in cleaning agents, aerosols, insulating foam, and refrigerants.

Correlating Censorship in the Peoples Republic of China and SARS - Air pollution has the ability to affect the earth’s entire ecosystem, as environmental scientists realized when they found direct links between ozone layer destruction and manmade pollutants called CFCs. To understand the ozone layer, you need to be familiar with the atmosphere as a whole. The ozone layer, which lies high up in the atmosphere, shields us from harmful ultraviolet (UV) rays that come from the Sun. Unfortunately we punched a hole in it, through the use of gases like chlorofluorocarbons (CFCs) in spray cans and refrigerants, which break down ozone molecules in the upper atmosphere.

An Analysis of Worship Rituals in Religious Ceremonies - The term ‘ozone hole’ refers to the depletion of the protective ozone layer in the upper atmosphere (stratosphere) over Earth's polar regions. People, plants, and animals living under the ozone hole are harmed by the solar radiation now reaching the Earth's surface—where it causes health problems, from eye damage to skin cancer. This is because ozone, together with ordinary molecular oxygen (O 2), is able to absorb the major part of the sun’s ultraviolet radiation and therefore prevent this dangerous radiation from reaching the surface. Without a protective ozone layer in the atmosphere, animals and plants could not exist, at . Ozone depletion consists of two related events observed since the late s: a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere (the ozone layer), and a much larger springtime decrease in stratospheric ozone around Earth's polar regions.
