Conservation of Ozone in Hong Kong 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 upper layer of the atmosphere surrounded by ozone (15 to 30 Kms) is known as ozonosphere. Ozone layer is a protective stratospheric layer‚ also known as ozone umbrella. Ozone concentration differs by about 10 ppm in stratosphere compared to 0.05 ppm in troposphere. It acts as a protective shield for the man‚ animals and plants by filtering out the lethal ultraviolet rays from reaching the earth’s surface. If the ozone layer is not there‚ the harmful ultraviolet rays will reach to the

• Depletion of ozone and formation of ozone hole • Ozone‚ in fact is a gas having fishy smell and O3 molecules which works as the protective shield for the life in the earth. It absorbs solar ultraviolet radiations and thereby protects life on the earth from several damage such as DNA mutation‚ skin cancer‚ blood cancer‚ etc. In the year 1985‚ NASA detected the thinning out of the ozone layer leading to the formation of ‘ozone hole’ in Antarctica. Since then the scientists have been regularly

Every time 1% of the ozone layer is depleted‚ 2% more UV-B is able to reach the surface of the planet. So in short‚ without the ozone layer everything on earth will burn. The ozone layer is just as important to us as oxygen‚ without it the harmful UV radiation would give us server burns and destroy our delicate ecosystems. Even though there is hard evidence that proves that ozone depletion is harmful for organisms on earth‚ there are a few groups who think that the ozone layer is a “myth” aka doesn’t

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

stratosphere. Tropospheric ozone is undesirable since it is a pollutant these‚ causing photochemical smog and greenhouse effect. In the stratosphere‚ it acts as a protectant since‚ (i) It absorbs the dangerous UV-radiations (ii) It helps to trap the weather pattern within the troposphere‚ by generating a temperative inversion in the stratosphere. Tropospheric ozone is increasing due to human activities‚ while stratospheric Or‚ is decreasing. This decrease is called Ozone Depletion Ozone depletion deals

Article Reflection: Ozone Layer Ozone: The Pollution Paradox This article was based on information about ozone pollution. In my opinion this article gave a lot of valuable information and I learned a lot of things I never had knowledge of. For example‚ the atmosphere forms and destroys the ozone‚ the ozone can have an effect on the human body and the article also provided information on what we could do about the ozone layer to help the atmosphere. I had a little bit of information in my

Ozone Our Global Sunscreen By Mike Carlowicz t’s not often that scientists get to conduct experiments that seem like they come out of a science fiction novel or a video game. Yet‚ that is what some researchers at NASA did a few years ago. Atmospheric physicists Paul Newman and Luke Oman built a simulation of the Earth’s atmosphere and then proceeded to strip away our protective ozone layer. Their computer model reproduced the chemistry and circulation of the air; natural variations in temperatures

Ozone depletion and Volatile Organic Compounds Christina Stelmach SCI/ January 20‚ 2013 Christine Snyder The atmospheric issue that I chose to write about is the Ozone layer depletion and the indoor air pollutant is Volatile Organic Compounds. I am going to talk about the cause and effect of each of these issues and also efforts to mitigate the issues. Our Earth’s Ozone layer protects all life from the sun’s harmful radiation. Due to all human activities damage has been done to our
