EARTH DAY TURNS 50
ABOUT 20 MILLION Americans turned out for the first Earth Day on April 22, 1970. Lectures and rallies took place at more than 2,000 college campuses, 10,000 elementary and high schools, and thousands of other places across the country. Forty-two states adopted resolutions endorsing Earth Day, and Congress recessed so that legislators could participate in the activities in their districts. It is sometimes described as, up to that time, the largest public demonstration in history.
The lectures and literature surrounding the event featured lots of dismal predictions about the future. One such compendium of doom was The Environmental Handbook, whose cover noted that it had been “prepared for the first national environmental teach-in.” Commissioned by the group Friends of the Earth, the book preached the perils of rising population and imminent depletion of nonrenewable resources. Many of its contributors—let’s call them the Catastrophists—warned that even such drastic actions as halving the number of human beings and stopping economic growth completely might not be enough to prevent the imminent ecological cataclysm.
A different group of researchers believed that while economic growth and technological progress had created some ecological problems, these things also would be a source of solutions. Let’s call these folks the Prometheans. The economist Theodore Schultz argued in the in 1972 that the expansion of modern agriculture would free up more land for nature. Other proponents of this more sanguine outlook included the oceanographer Cy Adler, the economist Christopher Freeman, and editor emeritus John Maddox, author of the 1972 book .
