Is the populations of the great apes in africa recovering and on the rise?

The correct answer is- NO

Explanation:

The population of great apes in Africa is declining at the rate of 2.7 % annually due to habitat loss, poaching, and diseases. International Union for Conservation of Nature's had put great apes in the list of critically endangered species.

A study found that there are more than 360,000 western gorillas in the wild which is 30 % higher than it was believed but still the numbers of great apes are decreasing very fast due to deforestation and unprotected areas from poaching.  

Therefore the answer is no because the population of great apes is declining in Africa.
