Officials of Virunga National Park in the Democratic Republic of Congo watch over the bodies of four mountain gorillas that were killed in summer of 2007 in this undated handout image. After a decade of relative calm for the mountain gorillas --the same cannot be said of the humans around them --wildlife officials report at least 10 have been killed this year. Environmental activists realise that wildlife conservation and tourism could be the key to survival for people as well as animals in a part of Africa where conflict has been the norm.
