the study author Robert Cowie said that the previous five mass extinctions on earth were caused by a series of natural phenomena. Now, biodiversity is really facing a severe test. The number of species has begun to decline sharply. Mankind is witnessing the beginning of the sixth biological extinction

for the sixth mass extinction, many experts said it was alarmist. Because the species extinction from the red list of endangered species of the World Conservation Union (IUCN) is not very serious, this extinction rate is in line with the current background

in this regard, koy pointed out that although the IUCN Red List of endangered species contains almost all birds and mammals, the records of invertebrates are incomplete. It is the extinction rate of invertebrates that has far exceeded the extinction rate of the existing background

in the past five mass extinctions, almost every marine species faced a major threat, and even the previous mass extinctions were mainly defined by marine invertebrates
