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

The ozone layer is a deep layer in the stratosphere‚ encircling the Earth‚ that has large amounts of ozone in it. The layer shields the entire Earth from much of the harmful ultraviolet radiation that comes from the sun. Interestingly‚ it is also this ultraviolet radiation that forms the ozone in the first place. Ozone is a special form of oxygen‚ made up of three oxygen atoms rather than the usual two oxygen atoms. It usually forms when some type of radiation or electrical discharge separates

Depletion of Resource Nowadays‚ world population is increasing ‚ this will affect the depletion of our natural resource. Large population increases in the developing world will strain resources and agricultural productivity (Eicher‚2008) .For Instance ‚ as populations grow‚ it may be necessary to convert additional land for agriculture housing development‚ and infrastructure. However‚ we need more products for our daily basic needs or extra needs for the upper class people . When high consumption

This layer of gas is called ozone and is located about five miles to 25 miles above the surface of the Earth. (Bright‚ 1991). Only about one-millionth of our atmosphere is made up of ozone. But it has a tremendously important job. Ozonecan absorb‚ or soak up‚ the part of sunlight called ultraviolet radiation. Some ultraviolet radiation still gets through

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

Air pollution is created by us humans when we use deodorants which consists of CFC’s that over a long period of time break down ozone particles and thus without even knowing we depleting the ozone layer.

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

Ozone As A Disinfectant Joey Finnegan Section 01 October 3‚ 2010 Ozone is a highly reactive gas composed of three oxygen atoms. Ozone is an unstable gas that can destroy bacteria and viruses. Ozone can have many different effects on humans depending on where it is in the atmosphere‚. Some of these effects can be harmful although some can be good. An excess‚ or high concentration of ozone in an inclosed area can be quite harmful to humans although in moderation and if used properly ozone

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
