They're populations are probably declining because their homes are being destroyed.

Answer: Due to deforestation

Explanation:

  • The population of great apes is declining in Africa because each year around 13,000 square kilometres of forest is being cleared for the purpose of agriculture and human settlement.
  • Deforestation at such a rate is destroying the native habitat of great apes and may lead to their extinction in the next 20 years.
