The vast majority of scientists who study climate issues now agree that carbon emissions are a potentially disastrous problem. However, economic fears have obstructed even the mildest remedies. Particularly in the United States, voters resist taxes that would raise fuel costs, and there has been little political support for massive investment in new technologies or mass transit systems.
Absurdly high prices have put lifesaving prescription drugs out of reach for millions of Americans and for hundreds of millions of people in developing countries. In large part, patent protection is to blame. The patent system is a trade-off: Consumers pay a monopoly price on a drug for 17 years to provide incentives for firms to undertake research that yields large profits. But the patent system is not the only way to support drug research. Alternatives that have a proven track record of success already exist--specifically, research supported by foundations, universities, and the government. Shortening patent terms and putting most pharmaceutical research in the public domain would cut costs for consumers as well as for government.
