Ecological Crisis - Other Examples

Other Examples

Some common examples of ecological crises are:

  • The Exxon Valdez oil spill off the coast of Alaska in 1989
  • Permian-Triassic extinction event 250 million of years ago
  • Cretaceous–Paleogene extinction event 65 million years ago
  • Global warming related to the Greenhouse effect. Warming could involve flooding of the Asian deltas (see also eco refugees), multiplication of extreme weather phenomena and changes in the nature and quantity of the food resources (see Global warming and agriculture). See also international Kyoto Protocol.
  • Ozone layer depletion.
  • Deforestation and desertification, with disappearance of many species.
  • Volcanic eruptions such as Mount St. Helens and the Tunguska and other impact events
  • The nuclear meltdown at Chernobyl in 1986 caused the death of many people and animals from cancer, and caused mutations in a large number of animals and people. The area around the plant is now abandoned by humans because of the large amount of radiation generated by the meltdown. Twenty years after the accident, the animals have returned.
