The animals that could become extinct in the year 2050 | Digital Trends Spanish


Climate change, human damage to the environment and depredation of ecosystems are some of the reasons that explain the decline of many breeds of animals. But the situation could be even more critical, since scientists from the Department of Zoology at the University of Otago in New Zealand predict that by 2050, 40% of the animal population could disappear from the face of the Earth.

Nic Rawlence, Director of the Otago Paleogenetics Laboratory and Senior Lecturer at DNA old, commented on lifescience that, “I think it’s quite likely. And, if species don’t go globally extinct, those that can’t adapt to our rapidly changing world are likely to experience range contractions, population bottlenecks, local extinctions, and become functionally extinct. The current extinction crisis may not have reached the height of the Big Five, but it is certainly on its way if nothing is done to stop it.”

According to Red List of Threatened Species of the International Union for Conservation of Nature (IUCN) Around 41,000 animals, about a third of all assessed species, are currently threatened with extinction.

Among these stand out:

The Sumatran orangutan (i put abelii), the Amur leopard (Panthera pardus orientalis), the Sumatran elephant (Elephas maximus sumatranus), the black rhinoceros (Diceros bicornis), the hawksbill turtle (Eretmochelys imbricata), Sunda tiger (Panthera tigris sondaica) and the Cross River gorilla (gorilla gorilla diehli ) — are classified as “critically endangered,” meaning they are at extremely high risk of extinction in the wild, according to the IUCN and the World Wide Fund for Nature.

There are countless lesser known species that are also at risk. A 2019 review published in the journal Biological Conservation they found that more than 40% of insect species are now threatened with extinction.

According to a 2022 report published in the magazine Naturetwo out of five amphibians (40.7%) are now endangered, while a 2016 report published by the journal Biology Letters has stated that, by 2050, 35% of frogs in the humid tropics of Queensland, Australia “could be threatened with extinction”.

Many species can, given time, adapt to climate changes and alterations to their natural environment. A 2021 investigation in the journal Trends in Ecology & Evolution found that some animals “are changing their morphologies” to better cope with the climate changeand some birds seem to be the most adaptable.

“To save the biodiversity we have left, we need to know how it responded to past and present climate change and human impact, so we can predict how it might respond in the future supported by evidence-based conservation management strategies,” said Nic. Rawlence.
