Humans are the greatest threat to the survival of endangered species through poaching, habitat destruction, and the effects of climate change. For some species, time on our planet Earth is running out.
Since 1996, the IUCN has classified the amur leopard as Critically Endangered with fewer than 70 individuals believed to exist today. It is hunted and killed for its beautiful fur, its habitat is being destroyed by human settlement and agricultural practices.
Cross river gorillas and mountain gorillas have been classified as Critically Endangered and Endangered by the IUCN since 1996, that is, two out of every five subspecies of gorillas. Currently, only 200-300 Cross River gorillas remain in their natural habitat and 900 mountain gorillas.
3. sea turtles
Two types of sea turtles are among the most threatened species in the world: the hawksbill turtle and the leatherback turtle.
In the last 100 years, the hawksbill has lost 90 percent of its population, 80 percent of which has been lost in the last 10 years. Starting in 1996, the IUCN classified it as a critically endangered species. The IUCN classifies the leatherback as Vulnerable, but many subpopulations face extinction.
Since the millennium, the IUCN has classified the Sumatran Orangutan as Critically Endangered, with approximately 80% of the population lost in the last 75 years, mainly as a result of massive deforestation. This terrible trend continues to put pressure on the remaining population of 6,600 Sumatran orangutans estimated to remain on this land.
5. Sumatran elephant
In the past 25 years, the Sumatran elephant has lost a surprising 70% of its habitat due to deforestation of palm oil plantations, agriculture, and human settlements. Less than 2,000 are estimated to exist and in 2011 the IUCN classified the Sumatran Elephant as Critically Endangered.
In 1992, the discovery of this mystical creature, sometimes known as the Asian Unicorn, in Vietnam was hailed as one of the most spectacular zoological discoveries of the 20th century. Still, this elusive and beautiful animal has been listed by the IUCN as Critically Endangered and is one of the rarest large mammals on Planet Earth.
At less than 100, believed to exist, the Vaquita is the rarest marine mammal in the world. Time is running out for these elusive little porpoises, with an expected extinction in 2018.
The tiger has long been hunted for its distinctive patterned fur. Of the nine subspecies of tigers, three are already extinct, many are in danger of extinction, but it is the South China Tiger and the Sumatran Tiger that currently face the greatest threat to their survival.
Tragically, the South China tiger is believed to be extinct in the wild as it has not been seen since the 1970s. The Sumatran tiger is the only surviving tiger subspecies in Indonesia and since 2008 has been classified by IUCN as Critically Endangered. Currently, fewer than 500 of these tigers exist compared to a population estimate of up to 1,000 in 1978.
Three of the five species in the Rhinocerotidae family are among the most threatened species in the world: the black rhinoceros, the Javanese rhinoceros and the Sumatran rhinoceros. The Java rhino is the most threatened with extinction with a total population of just 60 survivors in a national park in Java, Indonesia. The Sumatran rhino is critically endangered. It has been estimated that fewer than 100 exist today in the wild. The Black Rhino is classified by the IUCN as Critically Endangered with three subspecies declared extinct in 2011.
Despite their tough appearance, these small warrior-built mammals are losing the battle against poachers and habitat loss. All eight species of pangolin are threatened, from Vulnerable to Critically Endangered. They are the most trafficked animals in the world, hunted for their scales that can be sold on the black market for up to $ 3,000 / kg.
