global threats such as climate change and ozone depletion. 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

ozone layer or ozonosphere‚ region of the stratosphere containing relatively high concentrations of ozone‚ located at altitudes of 12-30 mi (19-48 km) above the earth’s surface. Ozone in the ozone layer is formed by the action of solar ultraviolet light on oxygen. The ozone layer prevents most ultraviolet (UV) and other high-energy radiation from penetrating to the earth’s surface but does allow through sufficient ultraviolet rays to support the activation of vitamin D in humans.

Introduction: When air gets polluted with dust‚ smoke‚ motor vehicles‚ mills and factories etc. is called air pollution. We know that air is an important element of our environment. But it is a matter of great regret that it is being polluted day by day in different reasons. Causes of Air pollution: There are different kinds of reasons of air pollution. The causes of air pollution are described below. 1. Using poison in agriculture: In agricultural sectors‚ farmers often use insecticides

The truth‚ that in the bid to improve our lives‚ we have put our own survival to stake‚ is finally hitting us hard. When is it that we are going to learn... when is it that we will understand that the well-being of the environment and our survival are intricately woven into each other. Good morning respected teachers and my dear friends ...today I Nikita am going to speak about how human activities are affecting flora and fauna? We are facing a serious crisis in biodiversity‚ the variety of animals

The Montreal Protocol on Substances that Deplete the Ozone Layer was adopted in 1987 as an international treaty to eliminate the production and consumption of ozone-depleting chemicals. A subsequent amendment created the Multilateral Fund for the Implementation of the Montreal Protocol‚ becoming the first of the multilateral environmental agreements to establish a financial mechanism for implementation. The World Bank has developed a strong partnership with the Multilateral Fund (MLF) since its

approximately 99% of all the liquid fresh water. More than 75% of underground water has a replenishment time of centuries or more‚ making it non-renewable. Increased water withdrawal from underground aquifers makes them more susceptible to droughts. Depletion of ground water may lead to land compaction that in turn decreases its ability to store water. All of the statements about ground water are true. * Instructor Explanation: The answer can be found in Section 5.1 of your text. Question 3. Which

The major sources of uncertainty include research and development‚ and market analysis. “Will the substitute product work and would it be working the same?” “Is the ozone problem really directly related to Chlorofluorocarbons‚ or a normal cycle has actually caused these observed recent changes?” Finally‚ “could Du Pont’s efforts really have an effect‚ and how much?” “Is this effect going to bring any profit for the
