Report comparing past mass extinction events warns that hunting and killing of ocean’s largest species will disrupt ecosystems for millions of years.

Humanity driving ‘unprecedented’ marine extinction

Humanity is driving an unprecedented extinction of sealife unlike any in the fossil record, hunting and killing larger species in a way that will disrupt ocean ecosystems for millions of years, scientists have found.

A new analysis of the five mass extinction events millions of years ago discovered there was either no pattern to which marine species were lost, or smaller species were the ones that disappeared.

But today’s “sixth extinction” is unique in the way that the largest species, such as great white sharks, blue whales and southern bluefin tuna, are being pushed to the brink, due to humans’ tendency to fish for larger species more often than smaller ones.
