Orangutans are some of the smartest animals on Earth, living high in the rain‑forest canopy of Borneo and Sumatra. This hi‑lo book explores how their long arms, gripping feet, and smart foraging skills help orangutans survive in the trees. Readers learn how orangutans build nests, use tools, and teach their young important techniques. The book also explains why orangutans are at risk—from deforestation and fires to hunting and the illegal pet trade—and why their slow reproduction makes recovery difficult. Clear text, vivid visuals, and critical‑thinking questions help developing readers understand why orangutans matter and how conservationists are fighting to save them.
