Why do some scientists believe that humanity is in the midst of a sixth mass extinction?

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.

Some time ago, there was sudden news that the earth is about to usher in the sixth mass extinction, as soon as the news came out, it caused concern in many countries, experts said that the culprit of the mass extinction is humans, what is going on? Mass extinction refers to a large-scale extinction event in a relatively short period of time, which means that a large number of different species will be completely extinct, according to previous research, mass extinction occurs about once every 62 million years, and the previous five mass extinctions occurred before the emergence of humans. This means that humanity may not be able to avoid mass extinction, and if it happens, I am afraid that humanity will also suffer a catastrophe.

According to **, a team of experts found that since 1500, there are more than 2 million known species on the earth, and some of them have been completely extinct, with a probability of about 13%. It is reported that investigating the extinction of invertebrates is a very important part of the research activities for two main reasons: first, there are more types of invertebrates, accounting for more than 90% of the known animal species, and secondly, invertebrates leave shells after death, so they are more convenient to study and the data obtained are more convincing.

After research, the team said that the expert group agreed that although the current time has not yet reached the 62 million year mass extinction cycle, the mass extinction has already begun to occur, and the cause is different from the extreme natural phenomena of the past, and the mass extinction is most likely caused by humans. Experts say that while there is no clear evidence to support this thesis, there is only one possibility that so many species of organisms will become extinct before the cycle has reached and there are no extreme natural phenomena, which are affected by other species, and humans are the only species capable of manipulating organisms on a large scale.

Experts say that human beings are the fastest of all species, and more adapted to the earth, so compared to other species, human beings are more capable, with the advancement of human science and technology, human beings have the ability to influence the biosphere, and it can even be said that human beings have been able to change the shape of the biosphere according to their own consciousness. In this regard, some people say that human beings are also a kind of evolutionary process and a kind of kind of earth's historical process, but experts believe that in the earth's history, human beings are the only species known to have advanced intelligence and developed advanced technology, so it is very likely that human beings have got rid of the law of species evolution. According to the data, the number of extinctions announced by the International Union for Conservation of Nature is 882, but after counting invertebrates, the real number of extinctions is very likely to exceed 150,000.
