International Orangutan Day

As most people probably know, orangutans are great apes native to the rainforests of Malaysia and Indonesia. Although they are currently only found in parts of Borneo and Sumatra, their range once extended to South China and Southeast Asia. Over the past few decades, the population of orangutans has declined sharply.

Over a hundred years ago, there were over a quarter of a million orangutans in total, but now there are estimated to be only about 100,000 of them. That makes them endangered in most of their geographic range but critically endangered in Sumatra.

That’s why it’s important for all of us to take urgent action, and we can begin by observing International Orangutan Day on August 19th each year.

The History of International Orangutan Day

International Orangutan Day was created by World Orangutan Events to promote the welfare and conservation of these great apes.

They created this holiday, as well as Orangutan Caring Week, to support these objectives and to help secure a better future for orangutans. These holidays continue to be celebrated to this day and will continue until orangutans have a better future.
