History of International Orangutan Day

The exact year that International Orangutan Day was established is uncertain. The day is marked, however, to save species that are on the edge of extinction. The goal of International Orangutan Day is to raise awareness about the predicament of this species, which has progressed from endangered to critically endangered. Orangutans have been around for generations and are thought to be the ancestors of gorillas. They are large apes who spend the majority of their time in trees and are only found in the jungles of Borneo and Sumatra, and the two species that live there were formerly thought to be the same.

Further research has shown that they are two distinct species that separated some 400,000 years ago. Orangutans have enormous arm lengths that reach about seven feet from tip to tip, which is impressive given that they only stand around five feet above the ground. When orangutans stand up straight, their hands are almost touching the ground. Their long arms compliment their arboreal lifestyle, letting them move from tree to tree and construct shelters from the canopy’s massive leaves. Because orangutans spend 90 % of their time in the treetops looking for food, deforestation is highly damaging to them. Orangutans are mostly herbivores, but omnivore orangutans will eat bark, insects, and even meat if it is available.

The tropical rainforest had been destroyed due to the farms’ improper management. Furthermore, the farmers consider the orangutans to be a nuisance and either kill them or burn the forest down. There have only been 20,000 survivors since 2006, but there should be more now. As a result, deforestation is the fundamental cause of such a tiny number of orangutans’ survival, and if it continues, the big apes will become extinct sooner. Raising awareness by commemorating International Orangutan Day can assist to increase the possibilities of this endangered species being rescued.

Unfortunately, humans are the greatest threat to the survival of orangutans. Deforestation, for example, encroaches on their habitat. In addition, illicit hunting claims the lives of 3,000 orangutans each year. Some wildlife specialists believe the orangutan will become extinct in the wild over the next 50 years. Though, several organizations are working to conserve orangutans. The Centre for Orangutan Protection, the Sumatran Orangutan Society, The Orangutan Project, Orangutan Outreach, and Humane Society are a few of these organizations.

5 Facts About Orangutans That Will Blow Your Mind

  1. They were first seen in Indonesia

    A hairy, crimson ape swaying from branch to branch in the beautiful green Indonesian forests was seen by the natives of Borneo and Sumatra.

  2. Humans of the forest

    We share 97% of our D.N.A. with orangutans, making them one of humanity's closest relatives.

  3. They have a long life span

    These intriguing apes have relatively long lives — they can live for 50 to 60 years in captivity and 30 to 40 years in the wild.

  4. Their solitary behavior

    Unlike other big apes such as chimps, gorillas, and bonobos, orangutans do not prefer to live in groups — a female will typically have a baby (or two), whereas males prefer to be alone.

  5. They have a huge arm span

    A male can reach seven feet from fingertip to fingertip with his arms.

Why International Orangutan Day is Important

  1. They are interesting

    Orangutans exhibit some astonishing behaviors, and discoveries are being found all the time. We can learn about their natural behavior in the wild, which will eventually lead to the adoption of conservation policies targeted at conserving orangutans and allowing them to remain happily in their natural habitat.

  2. They are so similar to humans

    Orangutans, like us, are apes. Although they are the Great Apes' closest distant relatives, there are just roughly 14 million years between us. This is a split second in evolutionary terms. When you gaze into the eyes of an orangutan, it might be even more difficult to pinpoint what it is that divides them from humans.

  3. They are endangered

    The International Union for Conservation of Nature classed orangutans as critically endangered in 2016. They are more vulnerable than ever before and rely on us to care about their safety.
