This has resulted in more efforts to drill and search other territories. The environment is being abused and this depletion of resources is one way of showing the affects. Mining still pollutes the environment‚ only on a larger scale. The US government has produced the Clean Air Act‚ the Clean Water Act‚ and the Resource Conservation and Recovery Act of 1976 in order

The most recognized depletion is the depletion of the stratospheric ozone layer. Pollution has caused this and has been reason for the increase in human health problems. Indoor air pollution and urban air quality are listed as two of the world’s worst pollution problems in the 2008 Blacksmith Institute World’s Worst

In recent years‚ the depletion of natural resources has become a major focus of governments and organizations such as the United Nations (UN). This is evident in the UN’s Agenda 21 Section Two which outlines the necessary steps to be taken by countries to sustain their natural resources.[4] The depletion of natural resources is considered to be a sustainable development issue.[5] The term sustainable development has many interpretations‚ most notably the Brundtland Commission’s ’to ensure that it

pollution is a serious problem that the United States faces each day‚ the problem is growing worse every year because of the millions of drivers on the road and the industrial factories going up around the world. The pollutants in the air are causing the ozone to get thinner and thinner‚ global warming has become a major problem‚ the ice melting in arctic places‚ hurricanes tearing through towns that have never had them before‚ tsunamis destroying everything in its path in China‚ and earthquakes killing

Abstract. In a world that is becoming increasingly industrialized‚ and in a world where more people can afford to drive cars‚ air pollution is becoming a very big problem. While there are those who would debate whether or not our air pollution is causing global warming‚ versus the earth ’s natural warming process since the last Ice Age. Definitive proof may or may not be found anytime soon. What is certain‚ however‚ is that there are confirmed problems caused by air pollution. These problems include

issue. Today‚ increasing population growth causes the natural environment to change greatly. This paper focuses on the negative influence of population growth on the environment in these areas: air pollution‚ water pollution‚ global warming and ozone depletion. Air pollution is an important pollution problem. Increasing population growth creates more of this pollutant whose major source is burning of fossil fuel‚ larger number of vehicles and industrial production. As a result‚ this leads to air

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
