Why do scientists think humanity is in the sixth mass extinction of life?

**At present, there are many animals living in such an era as human beings, these animals are the same as us humans, they are all created by our great nature, and these are also the whole food chain, but also part of the whole ecosystem, if the whole ecosystem is missing one of these animals, then the whole ecosystem will have a certain imbalance. But now a scientist's study shows that life on our planet is now in the midst of a 6th mass extinction of life, so why do scientists think so? There are several reasons for this.

1. The current state of the earth. First of all, the first point is that there is a very serious ecological problem in the interior of the earth. Such ecological problems have seriously threatened these life on the earth, especially our human beings have caused this series of ecological problems, we human beings have emitted a large amount of carbon dioxide caused by the gradual warming of the global climate, the global sea level is rising, and we have also emitted various toxic gases, causing many plants to die directly after receiving this toxic gas.

2. The dead part of the earth today. Another point is that many creatures on the earth have died many parts of the earth, such as the South China tiger white-sided dolphin that we know now, and some rarer animals in the past, such as the finless porpoise, these animals are facing endangered extinction, and this endangerment cannot be stopped by us humans. Because the needs of such creatures for the natural environment are extremely harsh, and we humans have polluted the interior of the earth, which has made it impossible for these creatures to live in such an environment.

Third, many species are disappearing year by year. Finally, the current rhinoceros has been sharply reduced to a situation where there are basically only a few dozen rhinoceros in the whole world.

Because species are now going extinct at an accelerated rate and the environment is changing rapidly, scientists believe that humans are in the midst of a sixth mass extinction of life.

Because everyone feels that many species are extinct on the earth today, isn't this the sixth mass extinction?

The reason why scientists believe that human beings are in the sixth mass extinction is because scientists have actually detected the mass extinction five times before, so they say that this is the sixth.

Since the birth of life on Earth, there have been five mass extinctions, each of which has resulted in the extinction of the vast majority of life. We humans, including our ancestors, Australopithecus, were undoubtedly very fortunate to be transported by land and did not make it to the last time. However, just because we didn't catch up with Siwan last time doesn't mean we won't catch up in the future.

Today, scientists in many fields, such as environmentalists, biologists, and ecologists, have called for more than once that if we are at the current scale of emissions, at the rate of resource consumption, and with the intensity of ecological and environmental destruction, the carrying capacity of the earth will be broken, and it will be possible to accelerate the great changes in the global climate and geological environment, triggering the sixth mass extinction.

Since <>modern times, with the rapid growth of population and the development of the economy, human activities have consumed more and more natural resources and energy, and a large number of various pollutants have been discharged, many of which have exceeded the natural carrying capacity and self-purification rate of the region. The expansion of desertified land, the shrinking of forests and grasslands, the pollution of wetlands, rivers, oceans and lakes, the decline of groundwater, the degradation of grasslands, the rise of sea levels, etc., the deterioration of the natural environment, and the increasingly serious destruction of biological habitats, have caused the living populations of many species to decline sharply, and have reached the point of extinction, and some have been destroyed.

According to the research and statistics of relevant departments, there are nearly three species extinct in the world at present, and the rate per hour has reached 1,000 times the historical average. The sixth mass extinction is by no means an exaggeration.

Although the current rate of biological extinction in the world is only a prelude to mass extinction, for us, whether it is a country or an individual, it is undoubtedly a strong body that should reflect and reflect. Extinction may not seem like much of an impact on us, but it reflects changes in the Earth's ecosystems at a rate that exceeds the thresholds and regulatory capacity of the species themselves. When the destruction of ecosystems adds up, we are the ones who are affected.
