extinction disaster

This great extinction has lost 95% of marine life and 70% of land animals. Catastrophic environmental changes also formed during this period.

US scientists concluded that the Earth was dark for two years after being hit by an asteroid 65 million years ago, Phys.org reported yesterday.

The catastrophe has wiped out almost all life on Earth more than 250 million years ago, and this event is happening at a faster pace than previously thought.

Renowned scientist Stephen Hawking has warned that humans must leave Earth in the next 100 years, otherwise facing the danger of extinction.
