00:02White rhinos still have habitats and could survive if they were not hunted.
00:07Due to the influence of humans, species die out hundreds to thousands of times faster than they would without them.
00:16This is according to studies.
00:19There have been five major species losses in the history of the Earth.
00:24About 450 million years ago, the sea level dropped and it became bitterly cold.
00:3185% of the species died, after which a new diversity developed.
00:36The next time, massive volcanic eruptions and oxygen depletion in the oceans killed off almost all life.
00:44Again, it was lava masses, fires and large quantities of greenhouse gases that caused the third mass extinction.
00:52An asteroid impact triggered the disaster that followed.
00:57And a good 60 million years ago, a meteorite crashed into the Earth, followed by earthquakes and tsunamis.
01:04The sky darkened and the planet was gripped by great cold.
01:07In this fifth event, the dinosaurs disappeared along with many other species.
