Mass Extinction

In “The Doomsday Book” by Marshall Brain, the Earth’s sixth mass extinction event looms large. This doomsday event is already underway in its early stages, and will only accelerate into an unstoppable cataclysm for all life of Earth unless humanity makes drastic changes in its behavior immediately. Humans are killing off species of mammals, bird, insects, reptiles, amphibians and fish using a number of destructive techniques:

  • Pesticides
  • Loss of habitat
  • Over-harvesting
  • Ocean acidification
  • Climate change and global warming
  • Pollution
  • Plastics
  • Artificial light
  • Oil spills
  • Deforestation
  • Rainforest collapse

Combine all of these forces together into an overwhelming onslaught on all forms of life, and millions of species will go extinct in the coming decades.
