Sumatran orangutans are critically endangered and without urgent action could be the first Great Ape species to become extinct. SOS is dedicated to turning this situation around. We do this by: Raising awareness about the importance of protecting orangutans and their rainforest home. Supporting grassroots projects which empower local people to become guardians of the rainforests Restoring damaged orangutan habitat through tree planting programmes. Campaigning on issues threatening the survival of orangutans in the wild. Help us protect orangutans, their forests and their future.
