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
deteriorating of the ozone layer, the ozone layer is a layer of ozone (O3 gas) in the atmosphere that reflects most of the Sun’s UV-B radiation (radiation that is harmful to humans and all living things). Additionally, the Montreal Protocol, is an international agreement to protect the ozone layer from deteriorating chemicals, it has been signed by 197 countries to protect the ozone layer. There are also many Canadian initiatives that are in effect to protect the ozone layer. These initiatives have
THE OZONE LAYER: THE PAST, THE PRESENT, AND THE FUTURE The Past The ozonosphere or as we know it, the ozone layer, is the region of the Earth’s upper atmosphere. It contains a high concentration of ozone molecules. The ozone molecules in the ozone layer work to block an estimated 97-99 percentage of solar radiation from reaching the Earth’s surface. If the ozone layer were not present the radiation from the sun would kill most living things and make our planet uninhabitable. The size and thickness
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
called ozone that filters deadly solar radiation. The Atmosphere The gaseous area surrounding the planet is divided into several spherical strata separated by narrow transition zones which is the atmosphere. (Graedel 1998) The upper boundary at which gases disperse into space lies at an altitude of approximately 1000 kilometers above sea level. (Graedel 1998) More than 99% of the total atmospheric mass is concentrated in the first 40 km from Earth's surface. (Graedel 1998) Atmospheric layers are characterized
the protective ozone layer that is over the Earth. Some people do not even think that the ozone layer exists even though The United States and over 180 other countries, saw that certain chemicals were causing the layer to start breaking down. To fight against those threats they signed the Montreal Protocol, this treaty agreed to phase
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 of
subtle ways: we 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. In effect, we are experimenting with the future, but unlike performing a laboratory experiment, which can be scrapped and begun anew if it fails, altering the climate is something that cannot be easily undone. Whatever happens, we shall all be forced to live with the consequences for a very long time. The author of Ozone and Climate Change - A Beginner'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
and had to use more of this gases to produce everyday objects and inventions by men. Little did we knew this chemicals we going to affect us in our life. Chemist Jose Mario Molina actually discovered that chlorofluorocarbons were affecting the ozone layer. Mario Molina was born on March 19, 1943, in Mexico City. Molina was interested in science since a very young age that he created his own and personal chemistry lab in a bathroom at his house. Molina's aunt was a chemistry and figured out her
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
ecosystem is constantly being disrupted. Overpopulation is placing heavy strain on the world's resources. We are burning all our fossil fuels to create the energy we need, and clearing our rainforests to make enough farmland to feed everyone. The ozone layer is slowly eroding, exposing us to harmful UV light. The room we have on this planet is just enough to provide for our population now! As the population grows, we will find ourselves more and more crowded, with no room left to expand. Solution: Transfer
and plants have never, and will never be discovered. Experts say, "Close to eighty percent of the terrestrial species of animals and plants are to be found there [in the rainforest],." As people tear down the rainforests they are affecting the ozone layer, and disrupting the process that lets plants fight the deadly amount of pollution the world produces every day. Over three thousand plants found can help the fight against cancer. Seventy percent of these plants are found in the rainforest. Periwinkle
1994, p.527). The massive amount of people has had highly destructive impacts on the earth’s environment. These impacts occur on two levels: global and local. On the global level, there is the accumulation of green house gases that deplete the ozone layer, the extinction of species, and a global food shortage. On the local level, there is erosion of soils (and the loss of vegetation), the depletion of water supply, and toxification of the air and water. The earth is dynamic though, all of these aspects
Not many people know about Green Chemistry. Yet if we had know about Green Chemistry back around 1951, when the world began to develop it’s industries - such as farming, after World War II we wouldn’t now be battling things such as damage to the ozone layer, diseases and harm to the environment, caused by chemical pesticides and dumping of chemicals into our oceans and other waterways. Not enough people realise the importance of chemicals and green chemistry in everyday life. Most people think of
grown and so has their consumption and exploitation of mother nature. Pollution and waste resulting from the depletion and usage of many natural resources and fossil fuels has plagued the earth recently. Two examples are the growing hole in the ozone layer and the greenhouse effect, which will continue to haunt us in the future. Along with this destruction comes the elimination of various species of animals and plants alike. The dollar sign is the biggest obstacle in combating this and although awareness
had ever expected. This movie served as the ultimate example what could happen if as a world community we do not clean up our acts. Continued consumption of nonrenewable resources, increased carbon dioxide emissions and further depletion of the Ozone layer could though most likely not on the scale illustrated occur in one form or another. The moral of this film is summed up by Dennis Quaid’s character in the last scene when he mutters his last few lines stating that hopefully humani...
The energy released from earthquakes and forces that move crustal plates are derived from the internal heat engine. Liquid water can exist on earth because the orbit is at the proper distance from the sun. The ozone layer is important to life on earth because it shields living things from uv rays. Constant change and state of flux on earth is caused by slow moving convection currents in the mantle. The internal heat of earth is a result of heat from radioactive decay of certain elements.

area where young people can make important contributions. We have many global problems, but we are lacking global institutions powerful enough to effectively address such problems as global terrorism, human rights abuses, global warming, the ozone layer, pollution of the oceans and rivers, arms trade, child soldiers, war, the weaponization of space, and nuclear and other weapons of mass destruction. Finding a way to participate in solving these and other global problems is one of the great challenges
