Discuss:

• What responsibility do individuals in the United States have to the rest of the world and to future generations in terms of staving off global warming? In other words, what type of economic sacrifice, if any, should the people of the US make to curb global warming?
• Should we allow developing countries to pollute more, or should we hold these countries to the same standards?

When considering this issue, I would like you to think about the opportunity costs.
