Ricochet has its list of the 13 most ridiculous predictions made on the first Earth Day in 1970. Our favorites are numbers six and thirteen:
Update: Here are 18 from Mark Perry.
“It is already too late to avoid mass starvation,” — Denis Hayes, Chief organizer for Earth Day
“The world has been chilling sharply for about twenty years. If present trends continue, the world will be about four degrees colder for the global mean temperature in 1990, but eleven degrees colder in the year 2000. This is about twice what it would take to put us into an ice age.” — Kenneth Watt
Do read them all and pick your favorites. Then do something serious like supporting capitalism. It has rescued the earth and its inhabitants by keeping present trends from continuing every Earth Day and long before that. Long may creative destruction reign.
