💡 Interesting Facts
1
Forest Gardeners: Orangutans disperse seeds by eating fruits, regenerating Sumatra's rainforests, with one individual spreading thousands of seeds annually. Their nesting behavior enriches soil, fostering biodiversity in ecosystems facing palm oil-driven loss.
2
Cultural Intelligence: They craft tools like sticks to fish for termites or leaf gloves for spiny fruits, with techniques learned socially, akin to human traditions. This intelligence, sharing 97% of human DNA, makes them a conservation priority in Sumatra's shrinking forests.
