The Human Footprint: Sixth Mass Extinction Explained

Scientists are now arguing that we are living through a mass extinction event in real time, one caused not by volcanic eruptions or asteroid impacts but by a single species. Sixth mass extinction explained covers the current...

Questions: 20 | Attempts: 10 | Last updated: Mar 8, 2026

Sample Question 1
What is the primary characteristic that distinguishes the Anthropocene from previous geological epochs?

Human activity is the dominant influence on climate and the environment

Massive volcanic activity in the Siberian Traps

A global drop in oxygen levels

The emergence of the first multicellular organisms

The collision of a large asteroid with Earth

Sample Question 2
To have the sixth mass extinction explained accurately, we must note that current extinction rates are estimated to be 100 to 1,000 times higher than the natural background rate.

True

False

Sample Question 3
Why is the sixth mass extinction explained by scientists as being unique compared to the "Big Five" extinctions?

It is caused by a single biological species rather than physical planetary changes

It only affects animals that live in the ocean

It is happening much more slowly than the Permian extinction

It is the only extinction that involves climate change

It is caused by a change in the Earth's orbit
