Are Humans the cause of Global Warming? How do we know global warming is caused by humans? Can global warming just be a natural cycle for earth? Global warming is a major problem in the world today. Having a hole in the ozone layer isn’t quite beneficial for humans no matter what the cause. Global warming is an increase in the earth’s average atmospheric temperature that causes corresponding changes in climate and that may be resulted from the greenhouse effect. The global average surface temperature

[pic]! [pic] ‘I’ll go out for a breath of fresh air’ is an often-heard phrase. But how many of us realize that this has become irrelevant in today’s world‚ because the quality of air in our cities is anything but fresh. The moment you step out of the house and are on the road you can actually see the air getting polluted; a cloud of smoke from the exhaust of a bus‚ car‚ or a scooter; smoke billowing from a factory chimney‚ flyash generated by thermal power plants‚ and speeding cars causing dust

Ozone depletion‚ greenhouse effect‚ and acid rain are man-made disasters. The ozone layer is the part of the Earth’s atmosphere which contains relatively high concentrations of ozone (O3). The cause of ozone depletion is the presence of Chlorofluorocarbons (CFCs) and related halocarbons gases in the atmosphere. In the presence of Ultraviolet light‚ these gases dissociate‚ releasing chlorine atoms‚ which then go on to catalyze ozone destruction. The greenhouse effect‚ on the other hand‚ is a natural

Elizabeth Reel Environmental Science SCI204 Section G Spring 2007 A Janice Webster Subject: Emission Testing April 22‚ 2007 Introduction With this paper I hope to gain a better understanding of emission pollution and the emission testing process. With my research and my visit to the local Clean Air Car Check site‚ I have compiled information that will prove valuable. I will define emission pollution and the major contributors. I will answer the why we have to emission test. I will

resources is the least to worry about; the use of all gasoline yields carbon dioxide. This carbon dioxide rises into the atmosphere and slowly tears away at the ozone layer by reacting with the chemical: ozone. As the ozone layer depletes‚ more of the sun’s harmful and heating rays penetrate the Earth warming it. If too much of the ozone is depleted‚ the globe’s average temperature will rise and throw nature off balance. Areas around the Earth’s equator are already feeling its effects. Drought plagues

Pollution and Society *By Osanyinpeju* Aisha We all know that pollution in our world effects two essential aspects of our planet: air and water. Although their pollutants are emitted in completely different ways‚ they both harm living organisms. Air pollution is predominately emitted though the exhaust of motor vehicles and the combustion of fossil fuels‚ whereas water pollution is the result of industrial waste and environmental accidents. Our society knows that pollution is harmful and a serious

altitudes‚ some of us find it difficult to breathe. Above the troposphere is the stratosphere. This zone is rich in ozone. Hence‚ it is also called ozonosphere. In ozonosphere‚ the sunlight converts oxygen to ozone by photochemical dissolution. The ozonosphere completely absorbs short wave solar radiations‚ such as ultraviolet (uv) radiations‚ x-rays‚ gamma rays etc. from the Sun. Oxygen and ozone of stratosphere provide protection from harmful solar radiation. It protects us from the bad effects of ultraviolet

People who live in big cities are badly affected by harmful discharge from plants and city transport and by the increasing noise level which is as bad for human health as lack of fresh air and clean water. Among the most urgent problems are the ozone layer‚ acid rains‚ global warming‚ toxic pollution of atmosphere‚ disappearance of forests‚ contamination of underground waters by chemical elements‚ destruction of soil in some areas‚ threat to some flora and fauna representatives‚ etc. One of the
