“The forest commands man, because it is in the forest that man makes its fields, hunts, collects fruits and medicine and after many years old villages become the forest again”
(Bakota elders, Gabon)

In West and Central Africa, estimates of the value of the bushmeat trade range from US$42 to US$205 million per year. The current harvest in Central Africa alone may well be in excess of 2 million tonnes annually, the equivalent of over 1.3 billion chickens or 2.5 million cows!

“Realistically, if changes in attitude do not occur soon…a fitting epithet for the loss of [Sulawesi] endemic mammals and birds may be 'they tasted good”

A more realistic starting point might be to treat the problem as one of ‘helping range states to better manage a resource in unpropitious circumstances’ – not of seeking to impose idealistic and externally-defined conservation aims as a short-term strategy
(Nasi et al.)
