Ozone Depletion and Indoor Air Pollution Nainsi McKinney 5/14/13 Ozone depletion is a very serious issue that is almost fully the fault of humans and the ozone is going to continue to thin if changes are not made. Chemicals that are used in everyday life are primarily responsible for the ozone loss; compounds called chlorofluorocarbons such as Freon and Styrofoam when used as a foam blowing agent for insulation (WileyPlus‚Chap.9.

The Importance of the Ozone "Like an infection that grows more and more virulent‚ the continent-size hole in Earth ’s ozone layer keeps getting bigger and bigger"(Beyond Discovery). The ozone is a protective layer that occurs naturally in the stratosphere‚ 6 to 28 miles in altitude. Each year‚ since the late 1970 ’s‚ much of the ozone layer above Antarctica has disappeared‚ creating what is popularly known as the "ozone hole." This hole now measures about 9 million square miles‚ nearly the

Ozone Depletion Good morning to our lecturer and my fellow friends. Today I want to deliver a speech on title “Ozone Depletion”. Did you know that about 20 kilometres from the earth’s surface there is a thin layer of gas forming just a small fraction of the earth’s atmosphere‚ without which harmful radiation from the sun would destroy all life on this planet? This is the ozone layer‚ which filters out harmful ultraviolet-B rays. Today‚ because of our negligence‚ the ozone layer is depleting.

The ozone depletion The ozone depletion‚ or ozone hole is a big problem which affects the environment and also all the people on earth. But what is it? Does this problem have a solution? And what are governments doing to reach this solution? The ozone layer is a belt of naturally occurring ozone gas that sits 15 to 30 kilometers above Earth and serves as a shield from the ultraviolet B radiation emitted by the sun which are very dangerous. Now‚ the problem is that the release of pollution

continent-size hole in Earth ’s ozone layer keeps getting bigger and bigger. Each year since the late 1970s‚ much of the protective layer of stratospheric ozone above Antarctica has disappeared during September‚ creating what is popularly known as the ozone hole. The Antarctic hole now measures about 9 million square miles‚ nearly the size of North America. Less dramatic‚ still significant‚ depletion of ozone levels has been recorded around the globe. With less ozone in the atmosphere‚ more ultraviolet

The Ozone Layer: What does it do and what happens when it is depleted? The ozone layer is one of the most debated scientific subjects of the last decade. The growing problem of its depletion is being researched heavily all over the world‚ and methods are being researched to try and solve the problem. There have also been many debates concerning the relationship between the ozone layer and the onset of global warming. Before solutions can be developed‚ however‚ what the ozone layer actually does

Conservation of Ozone in Hong Kong The ozone layer present in the stratosphere of the Earth is utmost important to us as it protects us from the exposure of ultraviolet rays which leads to several harmful effects. Without the ozone layer‚ human will be more prone to skin cancer and eye cataracts. Ultraviolet rays can also cause harm to marine life by reducing the amount of planktons and consequently depreciates the amount of fishes in the ocean. Besides that‚ the depletion of the ozone layer disrupts

Scientific Article: The Ozone Layer The Ozone layer is located in the Earth’s upper atmosphere. It acts as a barrier and absorbs majority of UV radiation before it hits Earth’s surface. Ozone is made up of three oxygen atoms that are naturally occurring molecules. The depletion of the ozone has become a worldwide issue and is caused by the release of CFCs into the atmosphere. CFCs release chlorine atoms which break down ozone molecules. The depletion of the ozone layer threatens to leave life on

Ozone depletion 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’sstratosphere (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
