Male Singing To Female That Will Never Come | Racing Extinction - 1 views

  •  
    "The Kaua Moho was the last species of it's entire genus and it was the last genus in it's family. This male was not just the last of his kind, he was the last being on his entire branch of the evolutionary tree, there was nothing left on the planet that was even close to being like him. That kind of loneliness is unimaginable. No other avian family has had every single species within it go completely extinct in modern times. Different species of Moho lived on each island of Hawaii and their evolutionary cousins the kioea birds lived alongside them, but starting in 1800 (about the time Europeans started arriving to the islands in significant numbers and also about the time the native human population of Hawaii also got decimated by diseases) one by one they died out due to the introduction of foreign avian diseases and parasites, habitat loss, and hunting for their plumage. 2 hurricanes within 10 years of each other finished them off. They are all gone and that song or any song like it will never be heard again save for in recordings. The hurricanes dealt the final blow, but 95% of it was humanity's fault. This has become common in Hawaii due to having so many species that only exist there. A LOT of those species are gone now because the arrival of Europeans brought disease, invasive species, and people straight up killed them or destroyed their habitats. It is a similar situation on every isolated island or area in the world as humans have expanded and explored every nook and cranny on the planet, no matter how hard it is to get to or how little business we have there we feel the need to interfere in even the most delicate and tiny ecosystem. Even the large, continent sized ecosystems are suffering. It doesn't matter if there are millions or even billions of an animal or plant, we will find some way to kill them all. It is only in the last few decades that serious steps have finally been taken to preserve the few areas on this world that we have not destroyed, but

Los insectos están desapareciendo y su extinción amenaza con destruir el medi... - 0 views

    "La velocidad a la que están desapareciendo los insectos es ocho veces mayor que la de los mamíferos, aves y reptiles, señala un informe "Los insectos son el corazón de toda cadena alimenticia, polinizan la mayoría de las plantas, mantienen el suelo saludable... La realidad es que los humanos no podemos sobrevivir sin los insectos", afirma Dave Goulson, de la Universidad de Sussex Científicos confirman la relación entre la química cerebral y la conducta se produce un descenso del 2,5% anual en la cantidad total de insectos, una cifra que sugiere que podrían desaparecer por completo en un siglo. EFE Los insectos de todo el mundo están camino de la extinción y amenazan con generar un "colapso catastrófico de los ecosistemas", según el primer análisis científico global. Las principales conclusiones arrojan que más del 40% de especies diferentes están disminuyendo en número y un tercio de ellas están en peligro de extinción: la velocidad a la que están desapareciendo es ocho veces mayor que la de los mamíferos, aves y reptiles. Según los datos más precisos que han podido obtenerse, se produce un descenso del 2,5% anual en la cantidad total de insectos, una cifra que sugiere que podrían desaparecer por completo en un siglo. El planeta está al inicio de la sexta extinción masiva de su historia: ya se han registrado colosales pérdidas en animales más grandes que son más fáciles de documentar. Sin embargo, los insectos son de lejos los animales más abundantes y variados, con una población 17 veces mayor a la de la humanidad. Los investigadores afirman que son "esenciales" para el funcionamiento de los ecosistemas, ya sea como comida de otras criaturas, para polinizar las plantas o reciclar nutrientes."

Plummeting insect numbers 'threaten collapse of nature' - 0 views

    "Exclusive: Insects could vanish within a century at current rate of decline, says global review The world's insects are hurtling down the path to extinction, threatening a "catastrophic collapse of nature's ecosystems", according to the first global scientific review. More than 40% of insect species are declining and a third are endangered, the analysis found. The rate of extinction is eight times faster than that of mammals, birds and reptiles. The total mass of insects is falling by a precipitous 2.5% a year, according to the best data available, suggesting they could vanish within a century."
