Two men speak in the floor lobby of a hotel overlooking the 117-square-kilometre (45-square-mile) Nairobi National Park in Nairobi, Kenya 13 November 2007. Wild animals are vanishing from Kenya’s oldest game reserve which borders the airport at Nairobi, the Kenya Wildlife Service (KWS) warned in a report earlier in the year. “The main reason for the decline in numbers is the explosion of Human population, encroachment into wildlife conservation areas and poaching,” KWS spokesman Gichuki Kabukuru said. Human activities — spurred by rapid population growth and the quest for higher standards of living — had undermined conservation efforts, wildlife activists added.
