The Top Five Environmental Disasters that Didn't Happen

For this year's Earth Day celebration, Reason.tv is proud to present "The Top Five Environmental Disasters that Didn't Happen." The environmental movement began in 1962 when Rachel Carson published her best-selling book Silent Spring. And ever since, chicken littles have warned us about imminent environmental disasters that ultimately didn't happen.

We all worried needlessly about acid rain, expanding deserts and global cooling, but these failed predictions weren't quite dire enough to make our list. To find out which prophecies of doom did make our list, you'll need to watch Reason.tv's "Top Five Environmental Disasters that Didn't Happen."

Approximately 7 minutes.

Produced by Feine, Manning, Jensen, Bragg, Swain, Epstein and Gillespie. Narrated by Melissa Palmer. Special thanks to Ron Bailey and Julian Morris.
