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 a grisly sunburn. Therefore, the ozone layer is the sunblock for the Earth, without it all organisms will be brutally charred. Moreover, the ozone layer is depleting gradually if not rapidly because of the effects of humankind. Although many people

Ozone Layer Information
The ozone layer is especially important to beings on Earth because the ozone layer is beneficiary for sustaining all life on Earth. Most if not all people do not know that there is layer of thick molecules that form the ozone layer. Without the ozone layer oxygen would not be kept inside the Earth’s atmosphere which would not allow organisms to support life since all living things need oxygen. Additionally, when the atmosphere, also known as the ozone layer, gets depleted it will cause many abnormalities in communities. Because the ozone layer is an immense permeable membrane allowing only certain amounts of sunlight to pass through; it helps prevents a lot of the solar energy from burning Earth’s surface,

During this period, all over 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 but because of human activities such as fossil fuel combustion, intensive agriculture and over global population take role and disturb the nature activity. They were increasing the level of greenhouse gases around the world. Ozone depletion is when the layer of ozone becoming thinner and thinner by some type of gases such as chlorofluorocarbon (CFCs). So that mean greenhouse effect and ozone depletion related to each other by be the main cause that make Global warming happen.
In summary, ozone is a multi-dimensional gas with its many influences on humanity and life in general. Some of its effects are considered essential while others are highly undesirable. Human-directed changes in the abundance of ozone, i.e., lower amounts in the upper atmosphere and higher amounts in the lower atmosphere, have created more problems for us and other organisms on the planet. There are clearly things that humans can and are doing that can alleviate these problems. Perhaps ozone can now begin to be understood for the vital (yet dangerous) resource that it is.
When CFC molecules reach the stratosphere, the sun's radiation breaks it apart, freeing the chorine atom to destroy ozone molecules. The effect is a growing ozone hole which forms over Antarctica in October and usually lasts through mid November. During the annual ozone hole, the amount of UV radiation that reaches the Earth can double. Ozone depletion serves as a major health risk for human beings. The three primary health effects of ultraviolet radiation on human health are damage to the skin,eyes, and immune system.
The ozone layer is the one that protects living things from the pure ultraviolet rays of the sun.
The article states experimental data has the potential to “shatter” the current belief system regarding ozone depletion (Schiermeier, 2007). The shattering may go all the way up to how scientists and ultimately the laymen understands the ozone hole formation occurs and the connection to changes in climate. The Montreal Protocol has been a big plus in how the hole may be managed, but the effects of those years freely using CFCs will still linger in the atmosphere for decades to come (Schiermeier, 2007). Interaction of CFCs and the sun rays are complex, but chemists at NASA’s Jet Propulsion Laboratory in Pasadena, California are relying on the new measurements to cast doubt on how the understanding of ozone holes are flawed. After experiments with a new photolysis rate applied to a chemical model of ozone depletion they found that 60% of ozone destruction at the poles has to do with anything else, but CFCs. The new finding is being tested by other researchers, but the possibility of the idea held for so long that ...
Global warming has been a continuous problem that has escalated over time on our planet Earth. The main cause of global warming is because Carbon dioxide and other warming pollutants are gathering in the atmosphere and laying over it like a thick sheet as well as its effect on the ozone layer. This is trapping the sun's heat and causing the planet to grow increasingly warmer as well as a variety of other weather shifts. Over the past 50 years, Earth’s tem...
Along with being aware about air pollution, we should also be aware about ozone concentrations and fossil fuel burning. The public should be concerned with ozone concentrations because they are constantly increasing. Ozone levels are increasing because of the heat and pollution. The public should be informed on how to reduce pollution and heat. Some steps the public can take to reduce pollution are to use public transportation and electric vehicles, conserve energy and recycle. Moreover, planting more plants will reduce heat and decrease ozone levels. Ozone is considered “bad” when found in the lower troposphere because it leads to many health effects in humans. Breathing ozone can cause bronchitis, emphysema, and asthma. Therefore, humans should stay indoors in the afternoon during the summer months. “Bad” Ozone also damages our crops and forests, affecting our food chain and the economy. Ozone is considered “good” in the Stratosphere because it protects us from dangerous ultraviolet rays released by the sun. Ozone in the Stratospheres protects us from conditions such as skin cancer and cataracts. Furthermore, ozone in the atmosphere protects our crops, thus playing
A thin layer of gas called atmosphere surrounds the Earth. The atmosphere serves two important purposes: it is a filter for the suns dangerous ultraviolet radiation rays and keeps the heat, necessary to maintain life on earth, within the stratosphere (Vorlat 361). Ultraviolet light is incredibly dangerous to all the organisms within the Earth's ecosystem because it causes skin cancer, effects the immune system, and harms plant and animal life. For that reason the atmosphere and the ozone layer within it are crucial to a stable life on this planet. The ozone layer is in danger, however. It is facing depletion by a toxic man-made substance called chlorofluorocarbons (CFCs). Together the international community is working through treaties and conventions to stop this environmental problem.
15.2) The accumulation of chlorofluorocarbons is responsible for depleting the atmospheric zone. The atmospheric zone has changed in concentration due to human activity. The CFCs release chlorine atoms which react with ozone reducing it to molecular O₂. Following chemical reactions release the chlorine which reacts with other ozone molecules in a catalytic chain reaction. The ozone layer is getting thinner and thinner as stable air at places such as Antarctica allows reaction to continue. The accumulation of CFCs has led to increased UV radiation in sunlight reaching the earth thereby decreasing ozone levels. The global temperature has increased.

A decrease on ozone and an increase in the amount of UV radiation reaching the earth has a significant effects on the eyes, such as an increased number of cases of "snowblindness" and cataracts. Snowblindness (photokeratitis) is a severe inflammation of the surface layers of the eyes. As this condition is caused by UV radiation a decreased in ozone will increase the number of incidences.
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 normalizing due to the Montreal protocol but the concentration of greenhouses gases within the atmosphere are escalating and we could see the melting of permafrost in Siberia and Alaska which contains vast quantities of methane which could lead to “irreversible environmental change”
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?
It can protect life on earth or harm it, but we have the power to influence ozone 's impact by the way we live.” ("Good Up High Bad Nearby - What Is Ozone?) This quote carries a very good point at the end of it. “The way we live.” Most Christians assume that if they are living for God and doing what the Bible says they are doing well in the eyes of God. That is true, Christians are called to a life of worship and service to God. The idea is that Christians do not recognize that there is a problem with the way they are living their lives that affects the planet. Personally, having heard sayings like “This planet is only temporary.” And “It will all fade away in the end.” These statements are true but it is taking advantage of the land God has provided for humanity. Being taught in the Bible that Christians should care for all of God’s creation, this expands to more than just humans, but to the animals and land as well. God in Genesis 2:15 took Adam, and put him into the garden of Eden to dress it and to keep it. If God did not care about the status of the Earth why would personally take Adam to the field just to take care of it. “For it pleased the Father that in him should all fullness dwell; And, having made peace through the blood of his cross, by him to reconcile all things unto himself; by him, I say, whether they be things in earth, or things in heaven.” (Barker and Burdick Colossians 1:19-20) Paul writes that to reconcile all things to
