About World Orangutan Day
World Orangutan Day, observed every year on August 19, draws global attention to one of humanity's closest living relatives, the great apes found only in the rainforests of Borneo and Sumatra. Orangutans share roughly ninety-seven percent of human DNA, and they are among the most intelligent animals on Earth, using tools, building elaborate nightly nests, and teaching their young for years longer than most mammals.
Their situation is dire. All three species, Bornean, Sumatran, and the Tapanuli orangutan, are critically endangered, with deforestation driven by palm oil plantations, logging, mining, and fires having removed vast stretches of their forest home. Fragmented habitat strands them in isolated patches, and orphaned infants rescued from the illegal pet trade require years of rehabilitation before they can return to the wild.
The day matters because orangutans are an umbrella species: protecting their forests also safeguards tigers, rhinos, elephants, and countless plants. Conservation groups mark the date with fundraising appeals, school programs, rescue-center visits, and campaigns for sustainable palm oil, proving that everyday shopping choices can ripple all the way to the canopy.

History of World Orangutan Day
Orangutans were known to Western science in the seventeenth century, but their deep story stretches back millions of years, when great apes ranged far more widely across Asia. Indigenous Dayak and Malay traditions held orangutans in special regard, and folk accounts described them as people of the forest, the literal meaning of the Malay name. Scientific understanding advanced through fieldwork in the twentieth century, most famously by Birute Galdikas, who began long-term study of Bornean orangutans in 1971 alongside fellow researchers Jane Goodall and Dian Fossey. Her research revealed their intelligence, slow life history, and solitary social lives. Awareness campaigns formalized as the species' decline accelerated: World Orangutan Day emerged in the 2010s, fixed to August 19, uniting rescue centers, zoos, and NGOs. The Tapanuli orangutan's discovery in 2017, with fewer than a thousand individuals, made the observance all the more urgent.
