Environmentalists Still Can't Get It Right

IBDeditorials.com: Editorials, Political Cartoons, and Polls from Investor's Business Daily -- Environmentalists Still Can't Get It Right

Here are my questions:

In 1970, when environmentalists were making predictions of man-made global cooling and the threat of an ice age and millions of Americans starving to death, what kind of government policy should we have undertaken to prevent such a calamity?

When Ehrlich predicted that England would not exist in the year 2000, what steps should the British Parliament have taken in 1970 to prevent such a dire outcome?

In 1939, when the Department of the Interior warned that we only had oil supplies for another 13 years, what actions should President Roosevelt have taken?

Finally, what makes us think that environmental alarmism is any more correct now that they have switched their tune to man-made global warming?
