How do CFCs cause the ozone layer to break down? Why is the destruction of the ozone layer dangerous? Why is the ozone layer in the stratosphere? Why are there ozone holes in the stratosphere? Why is the ozone layer important? Why is the ozone layer important to your health?
“PVC production is the largest and fastest-growing use of chlorine – accounting for nearly 40 percent of all chlorine used in the U.S. Chlorine is the basic building block of our most infamous toxic problems: CFCs, which destroyed the ozone layer, the dioxin contamination at Love Canal and...
To a group of environmental problems TNC's have been linked.Fifty percent of the green house emissions are generatedby them, in which they are responsible for global warming. Furthermore they are also the users of ozone-depleting chlorofluorocarbons (CFCs) and they are also producers of CFCs. ...
Depletion of Ozone is allowing more UV radiation which is causing more harm and we are also increasing the depletion by releasing Chlorofluorocarbons(CFCs), Ozone depleting substances by our activities. Recent research has proved that for every 1% decrease in Stratospheric Ozone there...
What are the advantages and disadvantages of air pollution? CFCs- aerosol, refrigeration, air conditioning and foam- blowing industries- destroy ozone layer. Methane-feedlots, rubbish dumps- global warming. Carbon monoxide- vehicle emissions- restricts oxygen uptake, causes drowsiness, headaches, death...

What are some effects of global warming? How do chlorofluorocarbons affect Earth's ozone layer? Is the greenhouse effect considered thermal pollution? What happens when sunlight hits greenhouse gas molecules? How potent is methane as a greenhouse gas? Why do CFCs damage the ozone layer? How do ...
A. Because the CFCs directly damage the people’s health. B. Because the CFCs are poisonous chemicals. C. Because the production of the CFCs costs a lot. D. Because the CFCs can attack ozone by liberating atoms of chlorine. 填空题 ...
These are carbon dioxide, chlorofluorocarbons also known as CFCs, water vapor, ozone, methane, nitrous oxide, and hydrofluorocarbons known as HFCs.Answer and Explanation: The rise in greenhouse gases is considered harmful because of the way these gases trap solar energy on the planet, leading to...
1) How do CFCs play a role in ozone depletion? Explain and include an equation to demonstrate your answer 2) What are the health effects of ozone in polluted air? In your own words, describe the manufacture of ammonia from natural gas, steam, and air. E...
