The history of life on Earth has been marked five times by mass extinction events of biodiversity caused by extreme natural phenomena. Today, many experts warn that the sixth extinction crisis is underway.

studying published Recently in biological reviews by scientists at the University of Hawaii suggests that rather than extreme natural phenomena, the latest round of extinction is Because of human activities.

“The dramatically increased species extinction rates and decreased abundance of many animals and plants are well documented, but some deny that these phenomena represent a mass extinction,” said Robert Coy, lead author of the study.

According to him, the “denial” view is based on a biased understanding of the crisis, which focuses on mammals and birds, and ignores the invertebrates that It clearly constitutes the vast majority of biodiversity.
to me Determine the estimates obtained for snails and land slugs, the study authors estimated that as early as the 1500s, land could have been lost in-between 7.5 and 13% of the million Of the well-known species, a number that reaches an impressive level 150,000 to 260,000 species.

“The inclusion of invertebrates has been helpful in confirming that we are indeed witnessing the beginning of the sixth mass extinction in Earth’s history,” Coy said.

The new study indicates that some People deny it too The sixth extinction has begun. Moreover, others accept it as a new and natural evolutionary path, because humans are just another species that plays its natural role in Earth’s history.

Denying the crisis, accepting it without reacting or even encouraging it, negates the common responsibility of humanity and It opens the way for the earth to continue The researcher commented on his sad trajectory toward the sixth mass extinction.

Scientists have linked the global extinction 445 million years ago to changing temperatures
