These were often driven by fears of overpopulation, pollution, and resource depletion.
Environmental and resource predictions
A new ice age: Some scientists in the 1970s predicted a new ice age would begin by the year 2000, based on the global temperature drop observed between 1945 and 1968.
Metal depletion: A 1970s estimate by a National Academy of Sciences scientist suggested that humanity would run out of copper shortly after 2000, while lead, zinc, tin, gold, and silver would be gone before 1990.
Mass extinction of species: A prediction from the secretary of the Smithsonian Institute suggested that 75-80% of all animal species would be extinct within 25 years (by 1995).
Overpopulation and starvation
Worldwide starvation: Some experts predicted that widespread famine would begin in India by 1975 and spread to other parts of the world by 1990, with the entire world, except for Western Europe, North America, and Australia, in famine by 2000.
Mass death in the "Great Die-Off": Paul Ehrlich predicted that a "Great Die-Off" would cause the deaths of 4 billion people between 1980 and 1989.
Collapse of civilization
End of civilization: Some scientists predicted the end of civilization within 15 or 30 years unless immediate action was taken on environmental issues.
