Then health status of many people in the world may be affected by diseases and injury caused by extreme weather conditions. The ozone is a major factor that makes life possible on Earth. Ozone located approximately 10-25 miles above the Earth's surface; in a part of the Earth's atmosphere called the stratosphere is very beneficial. The ozone layer is one of the oldest things on the planet, older than any of the ancient creatures we see in our museums today. As the area of polar ozone depletion commonly called the ozone hole gets larger, additional ultraviolet rays are allowed to pass through. As a result, scientists and researchers alike are beginning to ask questions about the symbiotic relationship between human well being and physical change.
It reaches over 560 kilometers 348 miles from the surface of the Earth, so we are only able to see what occurs fairly close to the ground. Sadly, cars are necessary to people because they depend on them to get to their everyday places and power plants are also necessary because people need power for almost everything they do daily. The reactions deplete ozone layer. At the same time this destroyed by various reactions with other components in the air. Surveys indicate that, by the year 2075, around sixty million Americans will succumb to skin cancer because of depletion of the ozone layer. According to British scientists, this surface ozone is responsible for the substantial reduction in the yields of major crops like wheat and rice. This warming of Earth due to greenhouse effect is a challenge to human civilization.
One of these oxygen atoms combines with 0 2 of upper stratosphere forming 0 3. What follows, will discuss the structure of the ozone layer, so that it can be understood what is happening when it is being destroyed. The same studies have further documented the harmful effects of ozone on human health, crop production and forest growth. Ozone depletion can also be caused by supersonic jet exhausts. Secondly, the environment in general will be negatively affected by the depletion of the ozone layer. The ozone layer is one of the most important source of protection that exists on Earth. It is an important issue because it concerns health and well being now and tomorrow.
Air has so much to do with the health and survival of many living organisms on this planet. As on September 2011, 191 states have signed and ratified the protocol. Because of the depletion of ozone layer temperature can spread the various diseases such as, skin disease and decrease of immunity, which can badly result in the atmosphere. Firstly, humans are blamed for engaging in activities that release more carbon dioxide into the atmosphere thereby depleting the ozone layer. The canopy of ozone layer is with variable extent less dense near the surface of the Earth compared to the height of 30 km.
Individuals and industries are to blame. In recent years, the ozone layer has been the subject of much discussion. They have found that the ozone layer naturally shields the Earth from ultraviolet radiation that in large amounts can be harmful. The treaty was opened for signature on September 16, 1987, and entered into force on January 1, 1989, followed by a first meeting in Helsinki, May 1989. The problem of ozone layer is governed today by Vienna Convention for the Protection of the Ozone Layer and the Montreal Protocol on Substances That Deplete the Ozone Layer.
The atmosphere contains less ozone than the common oxygen. The paper has looked at the causes of the ozone layer destruction and some of the effects it carries. The harmful gases rise to the stratosphere where the Ultra Violet Radiation then breaks them up and releases their chlorine. The effects of poisoning of the ozone layer will lash out on the marine ecosystem. Scientific Assessment of Ozone: 1994-Executive Summary 16. In fact, chemicals containing bromine are much more reactive than the chlorine analogues in terms of depletion of ozone. It is neither very flammable nor have chlorine.
This helps explain why there is less ozone in the Antarctic and Arctic polar regions. Therefore, Lack of enough oxygen leads to the decay of the unstable ozone, which in turn attack the molecules not protected by fluorine, when the ultraviolet rays from the sun hit. Ozone layer is by a large percentage destroyed by the greenhouse effect gases and human activity, a dangerous phenomenon which is on the rise impacting the globe negatively. Deforestation in all the countries, particularly tropical regions increased ultraviolet ray radiation. In short, what I mean is that destruction of the ozone carries with it an ugly destructive side.
Although stratosphere and troposphere constitute chemically identical oxygen atoms, they play different roles in the atmosphere and their depletion carry different effects humans and other living things. This increased burning of carbon in turn destroys the very fundamental storage of carbon. Methyl Bromide doesn 't stick around 15. How did scientist become concerned about the ozone layer? The ozone layer contains less than ten parts per million of ozone, while the average ozone concentration in Earth's atmosphere as a whole is only about 0. Current studies indicate that ultraviolet rays could be disastrous to the marine eco-system. 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.
If the proportion of fluorine is increased at the expense of chlorine, then a highly stable compound will be formed because the bond energy of C-F bond is larger than C-Cl bond. The canopy of ozone layer is with variable extent less dense near the surface of the Earth compared to the height of 30 km. Because of other measures taken, emissions of ozone-depleting substances are already falling. This destruction is of a serious magnitude, and it not only calls for the formulation of policies but also implementation of these policies to curb this global menace. For that reason the atmosphere and the ozone layer within it are crucial to a stable life on this planet.
