Questions:
1. Why will voluntary actions, undertaken at the individual level, be unlikely to bring about significant reductions in greenhouse gases such as CO(2)?
2. Does the fact that the CO(2) produced in one nation results in adverse effects on other nations have any bearing on the likelihood that CO(2) emissions will be reduced to the optimal level? Would the problem be easier to solve if all the costs and benefits were concentrated within a single country? Within a single elevator or office?
3. The policy approach to greenhouse gases will almost certainly involve limits on emissions rather than taxes are likely to be used?
4. It costs about $80,000 per acre to create wetlands. How reasonable is this number as an estimate of what wetlands are worth?
