La Tierra encaminada a una Sexta Extinción Global

La Tierra se acerca a su sexta extinción masiva

 

"Las depredadoras actividades humanas, están acelerando la sexta extinción masiva en la Historia de la vida en la Tierra, mientras la diversidad de vida, enfrenta la supresión definitiva de los muchos beneficios que nosotros cosechamos de la Madre Naturaleza, como, por citar sólo algunos ejemplos, la madera de los bosques, el aire, el agua, el ganado de los pastizales, los imprescindibles cultivos y los esenciales organismos vivientes de los Océanos, ríos, arroyos y manantiales.

"De no producirse un cambio radical en los Objetivos de Desarrollo Sostenible de emergencia propuesto por las Naciones Unidas, ya no habrá posibilidades de supervivencia en este Planeta y las eventuales



acciones para intentar salvar, conservar y restaurar la vital e imprescindible biodiversidad extinta, desde la escala local a la global, ya no serán suficientes para alcanzar salvar a tiempo la continuidad de la Vida en la Tierra"

Ante la extinción masiva (actualmente más de 5500 especies desaparecen para siempre cada año), ya no podemos garantizar, la continuidad del ser humano en este Planeta.

The Earth is approaching its sixth mass extinction

Humans creating sixth great extinction of all species, say scientists

The new study, reveals rate of extinction for species in the 20th Century, has been up to 100 times higher than would have been normal, without human impact. 21st Century, shows even worst.

"The predatory human activities, are accelerating the sixth mass extinction in the History of Life on Earth, while the diversity of life, faces the definitive suppression of the many benefits which we harvest of nature, as the wood from the forests, cattle pastures and the fish from the oceans and streams.



The Earth stands on the brink of its sixth mass extinction and the cause is exclusively ours



Millenary Corals dead in 10 years



In fact, the sixth global extinction, are being driven by the effects of just one single species: Homo Sapiens.

Such proportion of a mass extinction, as it is happening nowadays, has not occurred ever before (with the possible exception, 2.5 bn years ago, when a type of microbe evolved photosynthesis to spew out oxygen, a gas that would have been highly toxic to the other microbes living then, and these would have been pushed to the fringes of life on Earth – where they still remain). Even more extraordinarily, this single species is land-living, but, as never happened before, Man has managed to become the greatest lethal predator in the Oceans as well, causing populations of whales, fishes and all sea life to collapse.





"Unless we generate a radical change in the objectives of sustainable development of emergency, proposed by the United Nations, there will be no future opportunity of survival on this Planet and the eventual actions to try to save, conserve and restore the vital and indispensable biodiversity extinct, from the local to the global scale, shall no longer be sufficient to save in time the continuity of the life on Earth"

Due to the mass extinction (currently more than 5500 species disappear forever every year), we cannot guarantee any more, the continuity of the human being on this Planet.

Big Five mass extinction events occurred

Although the Cretaceous-Tertiary (known as well as K-T and The Great Dying) extinction event is the most well-known because it wiped out the dinosaurs, a series of other mass extinction events has occurred throughout the History of the Earth, some even more devastating than K-T Massive Extinction.

Mass extinctions are periods in Earth's History when abnormally large numbers of species die out simultaneously or within a limited time frame.

The most severe occurred at the end of the Permian Period when 96% of all species perished.

That global situation, along with K-T Massive Extinction , are two of the Big Five mass extinctions, that have devastated Life on Earth, each of which, wiped out much more than half of all species.

However, many smaller scale mass extinctions have occurred, indeed the disappearance of many animals and plants at the hands of man in prehistoric, historic and modern times will eventually show up in the fossil record as mass extinctions.

Ordovician-Silurian mass extinction
The third largest extinction in Earth's history, the Ordovician-Silurian mass extinction had two peak dying times separated by hundreds of thousands of years. During the Ordovician, most life was in the sea, so it was sea creatures such as trilobites, brachiopods and graptolites that were drastically reduced in number.

Late Devonian mass extinction
Three quarters of all species on Earth died out in the Late Devonian mass extinction, though it may have been a series of extinctions over several million years, rather than a single event. Life in the shallow seas were the worst affected, and reefs took a hammering, not returning to their former glory until new types of coral evolved over 100 million years later.

Permian mass extinction
The Permian mass extinction has been nicknamed The Great Dying, since a staggering 96% of species died out.
All life on Earth today, is descended from the 4% of species that survived

.

  

Triassic-Jurassic mass extinction
During the final 18 million years of the Triassic period, there were two or three phases of extinction whose combined effects created the Triassic-Jurassic mass extinction event. Climate change, flood basalt eruptions and an asteroid impact have all been blamed for this loss of life. 

              

Cretaceous-Tertiary mass extinction
The Cretaceous-Tertiary mass extinction - also known as the K/T extinction - is famed for the death of the dinosaurs. However, many other organisms perished at the end of the Cretaceous including the ammonites, many flowering plants and the last of the pterosaurs.

The Earth natural cyclical events, have extinguished almost the whole Life in this Planet and others nearby, at least five times. Nowadays, our Common
Home is inexorably approaching its cyclic sixth mass extinction, which have become extinct almost all life on this planet and others nearby, and now, annihilating human behavior, is causing and rapidly accelerating the sixth World shattering of all species, including ours, as well as Mother Nature's planetary disappearanceAnthör Zeît Geîst
