Silverback dead on the cover of Newsweek, from Virunga mountain. Seven dead gorillas total, 1% of all mountain gorillas left worldwide.
I visited there (Virunga gorilla refuge) in 1984.
The article, and National Geographic articles, attribute most species loss today to mining and forestry. In the case of forests, its obvious to go where the forests are. With mining, there may be deposits closer to cities but no one in his right mind would try to mine where people can see the pollution and destruction.
I went into recycling before Mobro because of things like this. They build roads into the wilderness, and it ruins the wilderness. If you take just 1,000 people into an area where there were no people before, it's trouble for big animals. And I despair, it just takes one asshole out of the thousand to kill a gorilla.
