According to the WWF report “Extinctions: we do not send the planet in red”, we are in the midst of the sixth mass extinction with an extinction rate 1,000 times higher than the natural one ‘
In 10 years, at least 160 species have become extinct. This is a high number, ascertained by the IUCN (International Union for the Conservation of Nature), but which probably represents an underestimate, both for the difficulty of research and for the lack of knowledge about some taxonomic groups, considered minor. The list of species that have disappeared, directly or indirectly, due to man is in fact constantly being updated.
And according to the latest WWF report, “Extinctions: we do not send the planet in red”, we are in the midst of the sixth mass extinction, with an extinction rate of animal and plant species 1,000 times higher than the natural one.
Often the declining species suffer from a variety of factors, so it is difficult to identify the root cause, but if there is one thing for sure it is that in all these factors there is the hand of man. About 25% of the 93,579 species listed on the IUCN Red List as Vulnerable, Endangered or Critically Endangered are threatened with global extinction.
Here are some of the species we have recently lost.
The northern white rhinoceros (Eratotherium simum cottoni) was declared extinct in 2018, when the last living specimen died, held in captivity (in the wild it became extinct much earlier due to poaching), it once lived in Sudan, Uganda , Central African Republic and Democratic Republic of the Congo. The Pinta Island tortoise (Chelonoidis abingdonii) officially became extinct in 2012, when the last individual discovered in the 1970s died. The Pyrenean ibex (Capra pyrenaica pyrenaica) was officially declared extinct in 2000, after a very hard hunt in the past centuries that led to a rapid decline.
The golden toad (Incilius periglenes) was declared extinct in 2004, also due to the rarefaction of its humid habitat, a consequence of the ongoing global warming. The lipote (Lipotes vexillifer), a freshwater dolphin found in the Yangtze River in China, was declared extinct in 2006 due to water pollution caused by the presence of many chemical industries and on the other hand by accidental catches during activities. fishing. The desert bettongia (Bettongia anhydra) is a small marsupial no longer observed in the wild since 1933, the IUCN only declared it extinct in 2016.
The Christmas Island bat (Pipistrellus murrayi) was declared extinct in 2017 due to a number of factors including the introduction of alien species. The Kauai akiaola (Akialoa stejnegeri), a bird from the Hawaiian Islands, was declared extinct in 2016. The last thylacine (Thylacinus cynocephalus), or Tasmanian tiger, died in the Hobart Zoo in 1936 and the species it was declared extinct by the IUCN in 1982. The Java tiger (Panthera tigris tuboica) was declared extinct in 1979 due to the destruction of forests to make room for plantations and from poaching.
Then there are the great auk of the Atlantic Ocean (Pinguinus impennis), the victim of a senseless hunt for food purposes and for its plumage (but the demand for specimens by the naturalistic museums has also contributed to its decline); the Atlas bear (Ursus arctos crowtheri), present in territories between Tunisia, Morocco and Algeria until the 19th century, the last individual died in 1867; the quagga (Equus quagga quagga), a subspecies of zebra widespread in South Africa until the mid-19th century, declared extinct in the wild in 1878 (the last individual in captivity died at the Amsterdam Zoo in 1883).
Thanks to the WWF “At Christmas put your heart” campaign, it is possible to support projects to protect biodiversity that we risk losing forever, by adopting or giving away the symbolic adoption of an animal in danger on wwf.it/adozioninatale2021. Rds 100% Grandi Successi relaunches its commitment to sustainable development, confirming itself as the radio partner of the campaign for the second consecutive year.
