99.9% of all living things have become extinct over the last 250 million years. Extinction is the permanent loss of species; birds, flowers, trees, fish. Over 100 species go extinct daily.
MASS EXTINCTIONS explores the five major mass extinctions known to have occurred. Each event is covered in depth to explain the cause and enumerate the species that were lost. What killed the dinosaurs? Did hunters in the prehistoric past cause the extinction of the Saber-cats and Mammoths? How do volcanoes effect our weather? Have extraterrestrial objects landed on the earth? When was the last mass extinction?
The foremost scientists in the fields of botany, zoology, biology, chemistry and paleontology present information about our environment and give their views on important issues facing the world today. Pollution, overpopulation and depletion of natural resources are examined as potential catalysts of the 6th MASS EXTINCTION.
