How does the current "Sixth Extinction" differ from the previous episodes of mass extinction in the history of life on Earth?

It is much faster in rates of species loss, and human activities are responsible for the faster rates.

The correct answer is Option (4) - It is much faster in rates of species loss, and human activities are responsible for the faster rates.

The current "Sixth Extinction" event differs from the previous episodes of mass extinction in that the current species extinction rates are estimated to be 100 to 1,000 times faster than in the pre-human times, and human activities are responsible for the faster rates of extinction.

The current "Sixth Extinction" is different from the previous episodes of mass extinction in the history of life on Earth in a number of ways.

First, the current extinction event is happening much faster than the previous extinction events. The previous extinction events occurred over millions of years, while the current extinction event is happening over a few hundred years.

Second, the current extinction event is being caused by human activities. The previous extinction events were caused by natural events, such as asteroid impacts and volcanic eruptions.
