The sixth event of mass extinction on Earth is in full swing, and the animal world is faced with "extermination," according to the latest research.
It was found that the rate of diversity of plant and animal life is far higher than we previously thought, and focusing on the species as a whole might not help long paths.
Researchers have found that about two types of vertebrate are extinct every year, which may not sound so dramatic, but is considered to be about 10 to 100 times the natural rate. But they also notice that it might conceal the worrying trend in which a particular population is cast out of existence because their distribution is fragmented and divided, which could be equally damaging.
Observing the spread of 26,700 different vertebrates, covering about half of all known birds, mammals, amphibians and reptiles, they found that more than 30 percent of the animals are declining due to the size and distribution of the population. They then analyzed the populations of 177 representative mammals in detail and found that all species analyzed lost more than 30 percent of their distribution, and incredible 40 percent of mammals lost up to 80 percent of their natural range.
"Mass extinctions have been observed as a loss of species," explained Paul Ehrlich, co-author of a study published in the Proceedings of the National Academy of Sciences of the USA. "But equally important – or even more important – the losses of the populations that make up those species. Why do we care about these populations? Well, for example, we lose the populations of birds, bats and insects that control pests and thus allow us to stay in high yield agriculture. "
So while certain animals do not have to be extinct, researchers warn that it is not important if their vital population no longer exists. For example, if a bee survived in a small population in Mexico and the species would still be maintained, the agricultural industry in the United States would still be destroyed because it has lost one of the most important types of pollinants at the local level
"It is therefore important to recognize that while the loss of the type is bad and largely irreversible, the loss of population and loss of populations from the population destroys our machinery to sustain life," continued Ehrlich.
This loss of species from one population to the other is bad news for us because the planet's health suffers. Ecosystems slowly lose their components, meaning that swamps no longer function as water purification systems or endangered forest survival by preventing floods. The disappearance of the population is also a precursor to the extinction of species, so more attention should be paid to the way in which the population and animal populations are moving.
