Which factor has contributed most significantly to the decline of Sumatran orangutan populations?

What is the approximate number of Sumatran orangutans remaining in the wild?

What observation did researchers document about Rakus after he treated his wound?

What is a significant aspect of the Sumatran orangutan's reproductive rate?

Rakus, a Sumatran orangutan, was observed using a medicinal plant to treat a cheek wound.
The wound was likely caused by a fight with another orangutan.
Rakus spent 13 minutes consuming the plant and then applied the juice to his injury.
The plant used was a liana vine, known to locals for its healing properties.
This is the first recorded instance of a wild animal using a medicinal plant to actively treat a wound.
Researchers observed Rakus's wound healing within five days.
Rakus returned to the plant to consume more leaves and increased his resting time to aid in recovery.

Sumatran orangutans are critically endangered, with fewer than 15,000 left in the wild.
Deforestation, driven by agricultural development, is a primary threat to their survival.
Orangutans are also captured for food and kept as pets, contributing to their dwindling population.
These primates have a slow reproductive rate, making them particularly vulnerable to threats.
