1960s: We were told the world would run out of oil within 15 years.

1970s: An imminent ice age was supposedly just around the corner.
1980s: Acid rain was expected to devastate forests and farmland.
1990s: The ozone crisis was portrayed as an unstoppable catastrophe.
2000s: Predictions claimed the polar ice would disappear within a couple of decades.
