This article explains some measures taken to preserve Chimp population :
""In the past few decades, European and Asian logging companies have built roads into what were previously untouched and inaccessible forests of Cameroon, opening up the wilderness to poachers," writes volunteer Sangamithra Iyer who worked at the Sanaga-Yong Chimpanzee Rescue Center in 2003.
"Large logging crews hire commercial hunters to provide food for them, while logging trucks often serve as conduits to transport illegal bushmeat to other markets. Even after the logging companies leave, the clear-cut lanes remain, providing poachers easy access to now vulnerable habitats of wild apes," Iyer wrote. "If current trends continue, statistics indicate that we may lose our next of kin within the next few decades."
Scientists estimate that, due in large part to the bushmeat trade, the remaining wild apes in Central Africa will be extinct within the next 15 to 50 years."
