Ozone Layer
Ozone, pronounced OH-Zohn, is a form of oxygen that is present in the earth's atmosphere in small amounts. Ozone in the upper atmosphere is a major factor in making life on earth possible. But ozone in the lower atmosphere contributes to air pollution.

Society has been widely addressed with the many problems that we are having in our environment today. A major problem is that of CFCs. CFC stands for Chlorofluorocarbons which are found in many of the aerosol spray cans. In December of 1973, Rowland and Molina discovered that CFCs can destroy The Ozone Layer
Ozone layer depletion slows There is good news about the ozone layer above us. The good news about the ozone layer is not always frequent. On International Ozone Day, the report came in that the ozone levels have decreased above Montreal and other residents of southern Canada.

The ozone layer shields the earth from most of the harmful radiation and light coming from the sun. The ozone reflects and absorbs the ultraviolet rays that try to come in. Without this kind of protection, all living things will be affected by these UV rays. Skin cancer develop

Ozone Layer Thinning Caused By CFC's "The ozone layer." What really is the ozone layer, and what does it do? Is it just a plastic covering over the earth? Why do we depend on the ozone layer so much for the earth's survival? Without the ozone layer there would not be life on this

    According to the U.S Environmental Protection Agency, or EPA, states “Information from clinical, epidemiological, and animal studies summarized above indicates that exposure to ambient ozone is a risk factor for triggering acute and chronic health effects. These include chest discomfort, cough, and shortness of breath and increases in daily mortality and hospital admissions for respiratory disease in the general population as well as those with lung disease; asthma attacks in people with asthma; and the possible development of new cases of asthma and other respiratory disease in people exposed to ozone over many years” (U.S Environmental Protection…

    The ozone layer is a section in Earth's stratosphere that sits between ten and fifty miles above the surface. The ozone layer is a protective barrier that exists between the life forms on Earth and absorbs the harmful ultraviolet-B raditation from the sun. This protective layer is essential in order for life to exist on the Earth. Ozone is a colorless gas that is formed by a chemical reaction of oxygen molecules, oxygen atoms, and solar radiation. Contrary to popular belief, ozone is actually a greenhouse gas and the loss of it would actually decrease the global warming effect on Earth instead of increasing it (Introduction). Ozone in the stratosphere is beneficial to life on Earth, but ozone at ground level is harmful to living things. Ozone on the ground level is made by sunlight reacting with motor vehicle exhaust gases and is a major component of smog in major cities. (Green Lane).…

    Ozone is produced when highly energetic solar radiation strikes molecules of oxygen O2 this causes them to split and produce O molecules. They then join with the remaining O2 and produce O3 molecules. These O3 molecules are what are known as Ozone. The "hole" in the ozone layer is not actually a hole it is a thinning of the ozone layer due to seasonal changes.…

    Hole in the Ozone is a documentary film that educates its audience the relationship of ozone and chlorofluorocarbons (CFCs) and its effects to our atmosphere. Hole in the Ozone also known as Ozone Depletion or Ozone Thinning had been an issue since the 70s and 80s. Even until now, this has become one of our major environmental issues. It is surprising to know that the ozone performs a major part in protecting us from dangerous radiation that the sun emits to our planet, even though it is also part of our pollution. As discussed in the film, the atmosphere is divided into several layers by density and temperature. In the second layer of the atmosphere, there lies our good ozone. I never knew that ozone is being build up in that layer, wherein it continues to be broken apart when struck be the sun’s radiation and combined again. As the process is being repeated, the ozone layer absorbs most of the solar radiation. But as they say, too much of everything is bad. The ozone could no longer fully protect us because as the solar radiation comes in and destroys the ozone compound, human activities in the earth also cause its depletion. Chlorofluorocarbons had been developed in the 30’s. This was even considered as a perfect compound because of its perfect qualities: non-toxic, non-flammable, non-corrosive, and non-reactant. But then, scientists started to suspect this perfect compound, and later discovered that the compound is being piled up in the troposphere and is destroyed in the stratosphere. It was intriguing to know that once this compound is destroyed, it produces chlorine atoms that kill the ozone. And the scary thing I learned too is that CFC lives up 75-100 years, takes 25 years to rise in the stratosphere, and worst of all, the CFCs effect we are experiencing now are the ones which were accumulated in the past. I hope this will be put to an end or we will suffer more in the future with life-threatening diseases like…

    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 the production of crops and forest growth, another two things which are essential to human life and another reason why the ozone layer is substantial to us (Gleason, K., 2008). The Montreal Protocol was created in 1987 for awareness to protect the ozone layer internationally and it is still ongoing until today according to the United Nations Environment Program (UNEP), which stated that another nation has just joined this protocol in January 2012 (United Nations Environment Programme, 2012). Hong Kong being a signatory to the Montreal Protocol has to play their part in contributing to the decrease of the usage of hydro chlorofluorocarbons (HCFC).…

    The ozone layer is a layer in Earth's atmosphere which absorbs most of the Sun's UV radiation. It contains relatively high concentrations of ozone (O3), although it is still very small with regard to ordinary oxygen, and is less than ten parts per million, the average ozone concentration in Earth's atmosphere being only about 0.6 parts per million. The ozone layer is mainly found in the lower portion of the stratosphere from approximately 20 to 30 kilometres (12 to 19 mi) above Earth, though the thickness varies seasonally and geographically.[1]…
