Human beings are the greatest threat to the survival of endangered species through hunting, habitat destruction and the effects of climate change.

Read on to learn which beautiful creatures are most in need of our help, protection and conservation.

Amur Leopard

Since 1996, the amur leopard has been classified by the IUCN as Critically Endangered with less than 70 individuals thought to exist today. It is hunted and killed for its beautiful fur. Its habitat is being destroyed for human settlement and agricultural practices.

Gorillas

Cross River Gorillas and Mountain Gorillas are both classified as Critically Endangered and Endangered by the TUCN since 1996—that is two out of five gorilla subspecies. There are currently only 200—300 Cross River Gorillas left in the wild, and 900 Mountain Gorillas.

Sea turtles

Two types of sea turtles are amongst the most endangered species in the world: the Hawksbill Turtle and the Leatherback Turtle. In the past 100 years, the Hawksbill Turtle has lost 90 percent of its population, 80 percent of which has been lost in the past 10 years. As of 1996, the IUCN classified it as a Critically Endangered species. The Leatherback turtle is listed by the IUCN as Vulnerable, yet many subpopulations are facing extinction.

Orangutan

Since the millennium, the Sumatran Orangutan has been classified by the IUCN as Critically Endangered with approximately 80% of the population lost in the past 75 years mainly as a result of mass deforestation. This awful trend continues to put pressure on the remaining population of 6,600 Sumatran Orangutans that are estimated to remain on this Earth.
