The battle to save Africa's endangered mountain gorillas
Civil war, deforestation, disease and poaching have driven the mighty mountain gorilla to the brink of extinction. Conservation efforts have helped boost population numbers, but humans are still their greatest threat.
"Are you ready?" the guide asks. He is wearing a green army uniform and heavy black boots. "We could spot one within the hour, but there's always a chance that we'll have to trudge through rainforest all day," he warns.

After listening to the guide's instructions, they set off into the rainforest with two armed rangers and a several porters in tow.
