99.9%of the species on the earth were extinct! Scientists admit that it is only a matter of time before humans disappear
Science frontier view of the world and the world of knowledge and understanding of the hole
The fossil record proves that 99.9%of the species that existed on the earth have been extinct, and about human beings Will it perish? Professor Nick Longrich of the University of Bath gave a positive answer. Researchers warn that the sixth biological extinction has come, and it is almost certain that humans will disappear like other species. Extinction is only a matter of time. Perhaps many people will ask, why do humans have science and technology that other species do not have, and medical means to extend lifespan, but will eventually go to extinction?
For this question, Professor Nick Longrich said that we do not Looking to the future, you only need to review history. As leaders in the past, such as:Neanderthals, Denisovans and Homo erectus, in that era, They should be at the top of the food chain, but in the end they are still perishing. In addition, another reason is that humans are not as strong as everyone thinks.
Humans also have weaknesses as large warm-blooded animals, such as In winter we need to wear thicker cotton or fur coats. In summer we need to wear cool T-shirts and shorts. Every day we need to eat enough food and nutrients. If we don’t eat or drink for a long time, we will face The risk of death.
In contrast, cold-blooded animals like turtles and snakes adapt to the environment It seems stronger, they can survive for months without food.
Same thing, once Tyrannosaurus, thunder dragon and other large warm-blooded animals are similar to human beings. They have extremely fast metabolism and require a lot of food intake. Because of this, they are susceptible to disasters such as volcanic eruptions, global warming, ice ages, or asteroid impacts. However, unlike dinosaurs, humans have smart brains, which can not only adapt to the environment of life at any time, but also open up the boundaries of survival.
Scientists say:Geographically widespread organisms are extinct The survival rate during this period is higher. A larger range of survival means that a species will not put all eggs in the same”basket”, but will be placed separately, if one habitat is destroyed, it can continue to survive in another habitat . For example, polar bears and giant pandas, which have relatively limited living ranges, do not have a wide range of life, such as brown bears and red foxes.
At present, humans are geographically distributed among all mammals on earth The largest species, living on continents around the world, remote ocean islands, and even harsh environments in deserts, tundra, rainforests and other places have human survival. However, although the large-scale habitats make humans not as easy to die as other species, humans have caused themselves many troubles, such as nuclear weapons, environmental pollution, food crises, overpopulation, and climate change (global warming ) And the spread of the virus.
In comprehensive consideration, scientists believe that the extinction of humans is only a matter of time . Nowadays, human beings have gradually realized the improper behavior of their own, and began to find ways to remedy:sign the Nuclear Non-Proliferation Treaty, try to maintain the world Peaceful situation; control environmental pollution and get as much afforestation as possible; implement family planning and implement corresponding measures for fewer births and better health; use cheap solar power to reduce the burning of coal and other consumables; develop epidemic vaccines to reduce disease risk. I only hope that it is not too late for the late”awakening”!
