The study, recently published in Biological Reviews by scientists at the University of Hawaii, suggests that, rather than extreme natural events, recent periods of extinction are caused by human activities. According to him, the “denial” approach is based on a biased understanding of the crisis, which focuses on mammals and birds, and ignores invertebrates, which apparently constitute the vast majority of biodiversity. When setting out estimates obtained for land snails and slugs, the study’s authors estimated that, since the year 1500, Earth has already lost between 7.5 and 13% of the two million known species, a figure that Contains a staggering 150,000 to 260,000 species. The new study suggests that some even deny that the sixth extinction has begun. Furthermore, others accept it as a new and natural evolutionary trajectory, as humans are just another species playing their natural role in Earth’s history. The researcher remarked, “Denoting the crisis, accepting it without response, or encouraging it, is an abrogation of humanity’s general responsibility and paves the way for Earth to continue on its tragic trajectory toward the sixth mass extinction.” ”, commented the researcher.

The history of life on Earth has been marked five times by mass extinctions of biodiversity due to extreme natural events. Today, many experts warn that a sixth extinction crisis is underway.
Study lead author Robert Covey said, “Species extinction rates have increased dramatically and many animal and plant populations have decreased, but some deny that these events were the cause of mass extinctions.” represent.”
“The inclusion of invertebrates was instrumental in confirming that we are indeed witnessing the beginning of the sixth mass extinction in Earth’s history,” Covey said.
New study suggests that some people deny That the Sixth Extinction has begun. Furthermore, others accept it as a new and natural evolutionary trajectory, as humans are just another species to play their natural role in Earth’s history.
