defects. The pollution from the ozone layer comes from the sun’s ultraviolet rays. Because sunlight has a critical role in its formation‚ ozone pollution is principally a daytime problem in the summer months. Ground level ozone is produced when sunlight combines with hydrocarbons and nitrogen oxide‚ two compounds produced by cars‚ trucks‚ and found wherever gasoline‚ kerosene‚ oil or natural gas are combusted. When temperatures are high ground-level ozone reach levels that are dangerous to health

possibly causing disease‚ death to humans‚ damage to other living organisms such as food crops‚ or the natural or built environment. The atmosphere is a complex natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth’s ecosystems. Indoor air pollution (see Airlog) and urban air quality are listed as two of the world’s worst toxic pollution problems in the

In todays world‚ Everyone uses some form of transportation. Whether it be a luxury jet or a bicycle‚ These means of transportation out do anything the people in the past could have even dreamed of. Some of these ways of transportation are good and some are not so good. Generally‚ our new ways of transportation opened up so many opportunities in our lives that we are blinded by the bad things that come along with it. For the most part‚ our advanced ways of transportation are positive. Cars and buses

trucks‚ and jet airplanes produce the most common pollutants‚ nitrogen oxides‚ gaseous hydrocarbons‚ and carbon monoxide‚ as well as particles of matter like lead. When nitrogen oxides combine with hydrocarbons they form other types of pollutants‚ like ozone‚ peroxyacetylnitrate which stings the eyes‚ and nitrogen dioxide which forms when nitrogen oxides react with oxygen. In cities where transportation is the major cause of pollution‚ nitrogen dioxide colors the sky brown‚ because the nitrogen dioxide

Air Pollution and Global Warming SCI 275 Cheryl Wilson September 30‚ 2012 Tori Robinson Air pollution causes global warming through the greenhouse effect‚ according to the United States Environmental Protection Agency. The greenhouse effect occurs when greenhouse gases trap and heat energy from the sun and prevent it from escaping Earth’s atmosphere and entering space.” (EPA‚ 2012) Atmospheric pollutions are caused by gasses and solid particulates released into the atmosphere.

means of production and productivity have taken the world to a new age. Leaving that apart another creation of science is pollution of the environment. Industrialization with the aid of science has polluted air‚ water‚ food and the atmosphere. The ozone layer is giving threatening signals. It is science‚ which gave birth to destructive weapons like dynamite‚ guns‚ rifles‚ rockets‚ atom bombs and hydrogen bombs which has increased the number of wars and has caused destruction to the world. So here is

these link up with ordinary oxygen molecules and form ozone. Some rejoin other free singles and revert to stable molecules. This Sun-energy process‚ if left undisturbed‚ maintains a fairly constant supply of ozone above the Earth’s surface. The ozone layer begins about eight miles up and is distributed thinly to about thirty miles up. This lofty umbrella of ozone shields the Earth from much of the Sun’s deadly ultraviolet rays. Without the ozone cover‚ life on Earth would be literally sunburned

The importance of environmental protection Environmental protection is an increasingly pressing issue all over the world. Ozone depletion‚ green house effect‚ global climate changes or global warming‚ etc‚ are the main issues in environment. Recent years‚ many countries and various organizations have paid more attention into environmental protection. A treaty about global environmental protection was discussed by 192 nations in Copenhagen in December 2011. But I fell every individual

Chyanne D-L and Emily H Over The years the planet has been changing. Humans are a huge part of that change. The impact that humans have on the planet is not good at all‚ because of our species; the ozone is thinning from all the air pollution. The astronauts are making the ozone layer even thinner by breaking it open as they travel through it to get to planets. There’s a garbage patch in the middle of the Pacific Ocean bigger than two football fields. The water is no longer safe in some places
