Two atmospheric problems have become major international issues—global warming and depletion of the ozone layer. Explain the causes of these problems and then compare and contrast the international management of each

What has led to success or failure in managing these problems? What might be done to overcome the failures? In your answer, consider the logic of the "tragedy of the commons."
What will be an ideal response?

Ideal Answer: The ideal answer should include:
1. Define both global warming and ozone layer depletion.
2. Explain the causes of both global warming and depletion of the ozone layer, such as the burning of fossil fuels, deforestation, and use of CFCs. Compare and contrast international attempts to curb these problems.
3. Discuss the paths to success and failure in managing the two problems, for instance, treaties have been more successful at curbing ozone depletion than controlling greenhouse gasses.
4. Analyze what might be done to transcend these failures, considering the logic of the "tragedy of the commons" in the process of doing so.
5. Offer a concise summary and effective conclusion.
