“Like in Vietnam, Laos and Cambodia, poaching is a major problem here, but in Sumatra, animals still have (but for how long ?) some space left to roam. For example, Sumatra is still home to at least 400 tigers, while the species is probably extinct in Cambodia and on the brink of extinction in Vietnam and Laos. “ says Olivier.
