These studies were carried out to determine and evaluate

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 earth or the people‚ but it does the exact opposite. One problem is the hole in our ozone layer. The ozone’s purpose is to block harmful ultra violet rays from the earths surface. These UV rays can cause skin cancer and can also produce the green-house effect. The hole in the ozone layer is caused by a man made product called aerosol. In aerosol there is a thing called CEF‚ this is what eats away at the ozone. CEF’s can also be found in refrigerators . Aerosol is a product that is used in many

floral scents the fate of three common volatile hydrocarbons emitted by flowers as they encountered increasing levels of ozone‚ hydroxyl radicals‚ and nitrate radicals. The researchers plugged these data into a model to test different air pollution scenarios ranging from conditions that prevailed during the 1840s to current summertime conditions in large eastern U.S. cities‚ where ozone levels can exceed 120 ppb by volume. Under 1840s conditions‚ only 20% of scents were altered by chemical reactions within

The pesticides‚ mercury and carbon dioxide that we release into the environment cause so many health problems to use and our children. It actually affects our children’s health more than it does to use. How can we do this to our environment knowing that it affects our health more and more. Dangers with in our Environment The

Air Pollution Earth is the only place in the universe that can support human life. It is very important that we realize this fact and take very good care of it. Various human activities cause the destruction of earth. Human beings can live a few days without food and water however humans can last only a few seconds without oxygen. Various human activities lead to the aggravation of the quality of air.

We‚ the people know that the ozone layer. We know that burning fossil fuel can destroy the ozone layer. If the ozone layer destroys‚ the world will get warmer and warmer and the people might die. We‚ people should decide which transportation we should use. We have to choose the right transportation to use. I’m going to tell

Many cities are notorious for their dangerously high levels of air pollution and the resulting health issues‚ such as asthma and emphysema. Summer heat and vehicle emissions are just a few of the contributing factors that increase air pollution levels. However‚ healthy trees planted effectively along roads‚ buildings and in parking lots can decrease overall air pollution levels for city residents.Trees can remove both gaseous air pollutants and particulate matter. Gaseous air pollution enters a tree

Stop Pollution: A Way of Saving Earth Since the rise of the advancement of awkward prepositional phrasing technology‚ pollution had already started its harm as well; awkward phrasing (personification?) from the dropping of the first atomic bomb‚ which results to land‚ water‚ and air pollution‚ to the industrialized world that pollutes the entire earth. People had been attempting to stop‚ or prevent it at least‚ to save the earth from dying but they were not successful. Meaning unclear However‚
