The current chimpanzee population is estimated at 200,000, compared with some 2,000,000 a century ago, and there are only a few thousand lowland gorillas and a few hundred mountain gorillas left.
Šimpanseid, keda sajand tagasi oli umbes 2 000 000, olevat praeguseks alles vaid 200 000, madalikugorillasid on kõigest paar tuhat ja mägigorillasid paarsada.
