Why are the Virunga Mountains Threatened

What makes the Virunga so special is that it is the oldest National Park in the entirety of Africa. (virunga.org) The Virunga mountains are threatened because of deforestation and shootings of animals. (news.mongabay.com) I don´t understand why people are shooting animals and why they are cutting down trees. There are lots of animals in the wild which they should try to limit killing let alone killing endangered animals. If the Virunga mountains get destroyed, that destroys the habitats for the endangered animals now. How would you feel if the Virunga mountains were destroyed?
