of the most serious problems in the modern world. Global warming means there is gradually increasing temperature on the earth‚ and consequently climate changing. Global warming is the result of human actions. The atmosphere is changing‚ and the ozone layer is under the threat from chemicals that people use on the earth. The amount of using fossil fuels‚ such as oil‚ gas‚ coal‚ and deforestation produces carbon dioxide. The global warming‚ as a result of man- made pollution‚ will increase not only

background Air pollution consists of many types. Smog‚ acid rain‚ ozone layer‚ and the green house effect destruction all cause serious problems for people and the environment. Smog and acid rain are caused by the release of noxious gases‚ like carbon monoxide. The ozone layer is being destroyed by another form of air pollution‚ Chlorofluorocarbons‚ even though these were band in 1995 people now use hydro chlorofluorocarbons‚ which destroy the ozone more slowly (maybe take this out?). Burning fossil fuels

many reasons of it but mostly it is caused by cars‚ growing cities‚ development of economy and industrialization. Clean air consists of several gases. When some other gases or dangerous elements get into the clean air‚ pollution is inevitable. Ozone layer is affected too much by pollution and it will cause serious disturbances on the environment. People are the main cause of pollution because the things that we use contain dangerous chemicals and they make atmosphere dirtier. Furthermore climate

than a dozen volatile organic compounds‚ some of which are known carcinogens; nitrogen oxides; sulfur oxides; and particulate matter‚ tiny particles of solids‚ such as metal and soot. Other emissions that affect human health and create smog include ozone and carbon monoxide. (See Reference 1) The good news is that despite the increase of vehicles on the road‚ air quality today is actually better than it was in the 1970s‚ thanks to the 1970 Clean Air Act.

Now‚ because there are so many cars on the road‚ the ozone layer is depleting and global warming is real‚ regardless if President Bush does not believe in it. What is going on? Where did all these problems come from? What are we going to do to solve these problems? Just relax‚ I know the root of this problem

Vidal de la Blache Geography is the science of places‚ concerned with the qualities of potentialities of countries. The particuler character of a country is expressed by the totally of its feature‚ the social diversities associated with the diversities of places.Geography mainly divided into two parts. • Physical geography • Human geography Physical

An example is the ozone layer is slowly being thinned out‚ which in turn is heating up the atmosphere of the earth. The thinning of the ozone layer is leading to changes with water level. The natural changes to the carbon cycle have been slowed compared to the rate at which humans are adding carbon dioxide to the atmosphere. (unknown)

PROJECT in our physics class to somehow lessen our environmental problem. Our project to be investigated is the HOMEMADEOR NATURAL INSECTICIDE. We all know‚ that our Ozone layer is getting thinner and thinner every time because of the chemicals we use daily. Now‚ to lessen the problem in our ozone layer‚ we are going to study about the use of natural insecticide. We can not only protect and help preserve our environment‚ we can
