There have been five large-scale biological changes on Earth, each of which led to the extinction of more than 70% of old species, and the evolution of new species. However, with the advanced evolution of human beings, they transcended nature to become the new masters of the earth.
Human beings have only been born for more than 200,000 years, which is almost a snap of the fingers compared to the evolutionary history of the earth. According to the normal evolution process of the earth, now should be the period of recovery of all things and the competition of all boats, and all kinds of wild animals should be in the stage of evolution to a higher level.
However, the advent of humanity has changed this process. The presence of humans has led to the replacement of forest meadows by high-rise buildings, reinforced concrete, and the extinction of wildlife. From the current state of life on Earth, it is not in the early stage of the evolution of the new Earth, but more like a precursor to the sixth mass extinction.
According to statistics, in the 20th century, there were 110 species and subspecies of mammals in the world, and 139 species and subspecies of birds became extinct. After entering the new century, the extinction situation has worsened, and 593 species of birds, more than 400 species of wild animals, 209 species of amphibians and reptiles and more than 20,000 species of higher plants have been nearly extinct.
The rate of extinction has accelerated 1,000 times since the Industrial Revolution, raising concerns among some scientists about a sixth extinction.
Dr. Jiang Zhigang, chief researcher of the Institute of Zoology, Chinese Academy of Sciences, said: "Since the beginning of the industrial revolution, the earth has entered the sixth mass extinction period. ”
Many species have become extinct on Earth, and today we have selected eight of the animals that left the last image record.
The first is the Balinese tiger, which is the smallest tiger in the world.
The Bali tiger originated in the Longdan region of Gansu Province, China, and subsequently migrated to Southeast Asia. Due to the hot climate of regions such as Malaysia, the Bali tiger gradually became smaller in size and became the smallest tiger on the planet. However, as humans developed, the habitat of Bali tigers was destroyed, leading to their extinction in 1937. This photograph is a video recording of the last Balinese tiger when it was captured.
The second is the North African antelope, a wildlife endemic to North Africa. Due to their peculiar appearance, the North African antelope was popular with European colonists, and a large number of hunting led to their extinction. This photo is the last North African antelope taken at a French zoo.
The third type is the Thai ze deer, which lives in the swampy areas of Thailand. Due to Thailand's economic development and population growth, the habitat of Ze Deer was destroyed, and the last Ze Deer was photographed in 1938.
The fourth species is the Atitlan, an endemic bird in Lake Atitlan, Guatemala. As the lake was developed into a tourist area, the number of Atitlan birds decreased dramatically, and the last one was photographed in 1990.
The fifth species is the donkey, which is extinct to the absurd, an endemic wild animal in southern Africa.
Due to the animals considered evil, the donkey is hunted on a large scale. The last spotted donkey died in the zoo in 1883, and this is its last photograph.
The sixth species is the thylacine, which is one of several carnivorous marsupials on the Australian continent. The extinction of large carnivores such as ancient monitor lizards and commingombatins has made it difficult for thylacines to survive. Coupled with the invasion of dingoes and human hunting, the thylacine became extinct in 1936.
This photograph is an image of the last thylacine when it was found.
The seventh species is the Caucasian bison, which was once widely distributed in Europe, but due to the development of the European industrial economy and the influence of colonial ideas, the Caucasian bison survived only in the Caucasus in 1927. Photographs of the last Caucasian bison being captured witness their extinction.
The eighth species is the Syrian wild ass, which lived in the northeastern highlands of Syria but suffered mass hunting during the colonial period.
In 1928, the last Syrian wild ass survived the shelling, and this photograph became their last video record.
The extinction of these eight animals is closely related to human activities. Nowadays, we can only know their existence through photos. Protecting wildlife is everyone's responsibility.
