My views of the environment are rooted in my belief in creation. I do not believe that life on earth began spontaneously‚ nor do I believe that the earth is so delicately balanced. I don’t believe that the earth and its ecosystem are fragile. Many radical environmentalists do‚ they believe man can come along‚ all by themselves and change everything for worse. After hundreds of millions of years‚ they believe that we are the last two generations of human existence. And they think we can destroy

on the air conditioner‚ we use Freon gas and when this Freon gas goes up to the Stratosphere where the Ozone layer is. And that Freon gas destroys the Ozone layer‚ so by that‚ we get more harmful ultraviolet rays from the sun that can cause our skin old or even cause skin cancer. So‚ I suggest that we should take buses when we go to somewhere not that far away because it actually helps our Ozone layer. Secondly‚ we have soil pollution. I think when farmer uses agricultural chemicals to their crops

The storm was nearly 400 miles wide‚ with the highest recorded wind gust at 104 mph. Overall damages were estimated in the $1.0 billion dollar range‚ and three deaths were attributed to the Category 3 storm. Copyright © 2005 by The McGraw-Hill

Man–made CFCs are the main cause of ozone depletion in the stratosphere and it will cause the development of skin cancer since ozone concentration of stratosphere reduced. Hence‚ I try to not open air conditioner and use fan to substitute. On the whole‚ I learned a

Te use of CFCs (chlorofluorocarbon) in many our daily equipments such as refrigerators and spray aerosols cause the depletion of the ozone layer that functions to protect us from the harmful effect of the sun and cosmic rays. The depletion of the ozone layer will increase the exposure of the dangerous cosmic rays to human and thus will increase the incidence of skin cancer. What can we do or at least minimize these problems? Responsible

Worldwide air pollution is responsible for large numbers of deaths and cases of respiratory disease.

Objectives: * To encourage students to throw their trashes at the right place * To help protect the ozone layer * To maintain cleanliness in the school campus * To encourage students to recycle Execution Plan A.

develop a better catalytic converter in the cars exhaust system to filter out harmful gasses. Chemistry led to the discovery of chlorofluorocarbons (CFC). Chemist further investigated and found that CFC is the main cause for the depletion of the ozone layer. The discovery of this organic compound led to the ban of all items containing CFC. Chemistry also makes our everyday lives easier. Chemistry was used to create the first transatlantic telegraph cable in 1858. This Invention made it faster

When we regenerate energy from natural resources like wind‚ sun‚ water and other non biodegradable substances we feel proud but when the consequences lie on ozone layer depletion‚ radioactive radiation make us afraid.
