centuries. Depletion of the ozone layer, however, has proven to be one of the most heavily regarded issues. Increased solar radiation was predicted to cause higher rates of certain cancers in many species, to be detrimental to the development of certain bacteria (some vital to agriculture), and to cause cortical cataracts. 1 The world united and responded with an advanced magnitude of international cooperation that has significantly slowed the formation of depressions in the ozone layer. Ozone depletion
Ozone depletion directly affects society and the environment through increased exposure to UV radiation on humans, animals, plants and materials. Increased exposure to UV radiation can have serious adverse side effects for humans: Skin Cancer UV-B radiation can cause benign and malignant skin melanomas. A reduction in ozone levels increases the amount of UV-B radiation that can reach earths surface which would cause an increase in the number of occurrences of skin cancers, sunburns and premature
Ozone Depletion Atmospheric ozone layer depletion is a serious problem currently facing the world. The ozone layer protects humans, animals, and plants from harmful ultraviolet rays. Money and time are being spent on ozone repair, but the problem still exists. The ozone layer is a region of the stratosphere containing ozone, or O3 gas. The ozone layer is essential to both plant and animal life on earth because it protects the surface from dangerous ultraviolet light. However, industrial
Ozone Depletion The world's ozone is depleting on a daily base. Individuals and industries are to blame. If we don't slow down what is being introduced to the atmosphere, the effects on humans and the earth will be devastating. We must stop killing the earth's ozone by watching what CFC's get released, car pooling to control automobile emissions, and stop industries from polluting our atmosphere. The problems with a depleting ozone layer are an increase in skin cancer, global
The Implications of Ozone Depletion on Human Health Introduction Hairspray. Refrigerators. Air conditioners. These everyday luxuries, while making human life more comfortable, are taxing our health seriously. Clorofluorocarbons, or CFCs, are anthropogenic chemicals used in refrigerants and as propellants in aerosols. CFCs, also known as freons, are also the primary culprit behind the depletion of stratospheric ozone, which allows harmful ultraviolet rays to reach the Earth and its inhabitants
The ozone layer diminishes more each year. As the area of polar ozone depletion (commonly called the ozone hole) gets larger, additional ultraviolet rays are allowed to pass through. These rays cause cancer, cataracts, and lowered immunity to diseases.1 What causes the depletion of the ozone layer? In 1970, Crutzen first showed that nitrogen oxides produced by decaying nitrous oxide from soil-borne microbes react catalytically with ozone hastening its depletion. His findings started research on
Destruction The Greenhouse effect and ozone depletion are two of the most prevalent environmental issues faced globally today. Greenhouse gases have the ability to absorb infrared radiation from the sun. Global warming refers to an increase in average global temperature due to natural and anthropogenic causes. Ozone depletion describes an observed decline of 4% ozone per decade in the total volume of the Earth’s stratosphere and seasonal ozone depletion events. Ozone levels within the stratosphere are
The depletion of the ozone layer has been a trending topic after it was first discovered in 1970. The ozone layer is a portion of the earth’s stratosphere which absorbs most of the sun’s UV rays hence preventing cancer and other fatal illness to the skin. It contains high concentrations of O3 and at a constant rate is being broken down and. Since 1970, it has been discovered that about 4% of the ozone layer wears off every decade and is as a result of day-to-day human activity. From the day-to-day
The Ozone layer is getting smaller and smaller. It’s constantly and slowly shrinking by 4% every decade or 10 years, and it stared a long time ago. This event is known as Ozone depletion, ozone depletion is the event of "the Ozone layer" (which is in Antarctica) starts to become damage and is caused by the chemical element stratospheric chorine. Stratospheric chorine is one of the many chemicals that can destroy the Ozone layer. There are many ways to stop it or control the amount that it melts
Depletion of the Ozone Layer The atmospheric ozone layer protects all living things from the harmful effects of the Sun. In recent years however, much damage has been caused to the ozone layer, causing it to decrease in size. The depletion of the ozone layer has and will continue to have many detrimental effects on all living things on this planet. A thinner layer will allow more of the sun’s ultraviolet radiation to reach the Earth’s surface. In particular, it will be the increase of UV-B
have thinned the ozone layer and may now be starting to change the very climate system upon which we and all other life on Earth depend on. It’s like we are experimenting with the future, but unlike lab experiments, we can scrap it and start a new one is it fails, but altering the climate cannot be easily undone. We will be forced to live with the consequences for a very long time. Undoing what we have done to the ozone layer is not that simple. What is the ozone layer? The ozone layer is a part
the world is facing with one of the biggest problem, the Global Warming. Global Warming makes average level of Earth’s temperature increasing this is causing by two main phenomena; increasing of greenhouse gases levels all over the world and ozone depletion in the atmosphere. Greenhouse effect made up by several groups of gases that we know as greenhouse gases. In general, the levels of these gases were controlled by nature, so the level of the greenhouse gas was constant and in the appropriate amount
The Effect of Stratospheric Ozone Depletion on Aquatic Ecosystems Introduction Throughout the years, advances in technology and scientific development have greatly influenced our global community. Various anthropogenic factors, such as the increased combustion of fossil fuels and widespread usage of manmade chemicals, have greatly affected the planet's atmosphere and it's ozone layer. Ozone Depletion The stratospheric ozone layer is the Earth's natural means of protection from the Sun's
Global Warming and the Depletion of the Ozone (O3) Layer The average surface temperature on Earth has increased approximately 1.0°F in the past century, and it is projected that it will again increase somewhere two and nine degrees by the year 2100. This is the expected effect of increased greenhouse gases, which contain the Sun's energy (heat) in the lower atmosphere (troposphere). Much of the increase in these gases can be considered a natural occurrence, however, at least some of it is human
air every day by throwing out enormous piles of garbage, burning tons of fossil fuels, and driving millions of miles each year, but do we truly know how much this affects our society and our Earth? Smog, acid rain, the greenhouse effect, and ozone depletion are some of the effects that have resulted from air pollution. Health effects caused by filthy air are also a serious problem that has resulted from pollution. Smog is a term that was created from smoke and fog. It is found most typically in
Ozone Depletion? What is that? Ana S. Reyes South Texas College Ozone Depletion? How Important is that? Earth is surrounded by an invisible shield that is 6.2 miles long; furthermore, it absorbs most ultraviolet rays that the sun casts down to the biosphere. Without this shield, also known as the ozone layer, all life on Earth would cease to exist because of the harsh rays the sun emits. An example of how the ozone protects species is when a person goes out into the sun without sunblock, they get
Ozone Layer Depletion In the 21st century, some major issues have emerged along with the advancement of science and technology, ozone layer depletion is one of them. Ozone layer depletion has become a worldwide concern due to the rapid deterioration of the volume of the ozone layer, also for the increasing threat to all living organism and their functions. Increasing uses of CFCs and halocarbons have led to an emergence of various health issues and environmental problems which are in some cases
The ozone layer is one of the layers of Earth’s stratosphere. The ozone layer absorbs radiation that hits Earth from the sun. Ozone is a good trapper of types of radiations such as ultraviolet radiation or UV light. UV light can penetrate organisms’ protective layers, such as skin, damaging organisms’ DNA molecules. Ozone molecules are made up of three molecules of oxygen atoms and it is always being destroyed and naturally restructured however, chlorofluorocarbons (CFCs), which is a nontoxic, nonflammable
surprising result in his calculations concerning the CFCs and ozone layer. CFCs are basically inactive in the troposphere(around the altitude of 50,000 feet) so it would gradually drift upward until they reached the mid-stratosphere.(about 100,000 feet) At this point CFCs would be broken down by short-wavelength ultraviolet radiation from the sun. This radiation is the one which would not reach the lower atmosphere in large amounts because of the ozone layer. When these CFCs do brake down, they released atomic
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 size of
