Why is the Smell of the Rainforest So Important?


Rainforests are amazing in so many ways

Did you know that the scent of a rainforest helps create rain? And what's more—orangutans play a crucial role in keeping the whole system in balance.

Rainforests are incredible places—teeming with vibrant sights, sounds, and smells. But did you know that the very scent of a rainforest plays a crucial role in creating rain? Yes, you read that correctly! ⁠

Rainforests are vital to the planet’s water cycle, particularly through evapotranspiration—the process where water moves from the Earth’s surface into the atmosphere.

Rain is a product of condensation, but to produce each drop of rain, water molecules need something to condense on. These surfaces can include pollen, salts and ice crystals – and, in the rainforest, volatile organic scent compounds released by leaves. Is there anything rainforests can’t do if we look after them?⁠

Orangutans help maintain the delicate balance of life in the rainforest. Their presence is a sign of a healthy, functioning rainforest. By protecting orangutans as a keystone species, we safeguard entire ecosystems, which are crucial for the health of our planet.
