Earth Day Predictions:
"Civilization will end within 15 or 30 years unless immediate action is taken against problems facing mankind." — Harvard biologist George Wald
"In a decade, urban dwellers will have to wear gas masks to survive air pollution… (in 15 years) air pollution will have reduced the amount of sunlight reaching earth by one half." — Life magazine
"Population will inevitably and completely outstrip whatever small increases in food supplies we make. The death rate will increase until at least 100-200 million people per year will be starving to death during the next ten years." — Stanford University biologist Paul Ehrlich
In 30 years, if present trends continue... there won't be any more crude oil. — Ecologist Kenneth Watt
These predictions were made 43 years ago on the first "Earth Day" in 1970. Here are my 2 favorites:
"The earth's cloud cover will continue to thicken as more dust, fumes, and water vapor are belched into the atmosphere by industrial smokestacks and jet planes. Screened from the sun's heat, the planet will cool, the water vapor will fall and freeze, and a new Ice Age will be born." — Newsweek magazine
"The world has been chilling sharply for about twenty years. If present trends continue, the world will be about eleven degrees colder in the year 2000. This is about twice what it would take to put us into an ice age." — Kenneth Watt
