Chemistry Ozone Depletion Ozone depletion describes two distinct but related phenomena observed since the late 1970s: a steady decline of about 4% per decade in the total volume of ozone in Earth’s stratosphere (the ozone layer)‚ and a much larger springtime decrease in stratospheric ozone over Earth’s polar regions. The latter phenomenon is referred to as theozone hole. In addition to these well-known stratospheric phenomena‚ there are also springtime polartropospheric ozone depletion events. The

show you more about ozone depletion and how it relates to indoor air pollution. According to our text ozone "is a naturally produced‚ essential component in the stratosphere‚ which encircles our planet some 10 to 45 km (6 to 28 mi) above the surface." (Berg‚ Hager‚ & Hassenzahl. 2011). Ozone in the stratosphere is a good thing‚ when in this layer it absorbs much of the suns ultraviolet rays and protects us from harm. In the troposphere however‚ it is a different story. Ozone there is a combination

The atmosphere allows human‚ plants‚ and all the earth’s creatures big and small to exist.

DW 4 Question: Are the concerns over globalization justified? Globalization is one of the most vibrant‚ contested‚ and debated issues in modern international relations. Some argue that globalization brings great benefits‚ while others argue that globalization is fundamentally flawed. Countries in the world today are largely interconnected‚ whether through trade relations‚ cultural exchanges‚ multinational cooperation on world issues like the environment and natural resources.

people are killed worldwide every year due to air pollution. So‚ it has shown us how seriously the tendency of air pollution all around the world. This environmental issue has brought us a lot of effects like greenhouse effect‚ acid rain and ozone layer depletion. One of the effects of air pollution is greenhouse effect. Greenhouse effect means the phenomenon whereby carbon dioxide traps solar radiation in the earth’s atmosphere. As the heat is trapped in the atmosphere‚ the temperature is rising

However‚ the existence of state sovereignty as well as the political and economic interests of countries remains barriers for cooperation between nations. Thus‚ highlighting the ineffectiveness of international law in its role of achieving global environmental protection. The growing awareness of global threats such as ozone depletion led to international calls for the reduction of ozone depletion pollutants‚ CFC’s and nitrate oxides. The

Central idea: The ozone layer/"hole" is caused by fluct. in the environment and CFC’s are little if any of the cause of ozone depletion. CFC’s are very heavy‚ they stay close to the ground and do not affect the stratosphere. Volcano’s put out approx 10X more times chlorine than man produces.
