sustainable managemengt is seen as a a practical way of protecting species from extinction.instead of depending on largely ineffective illeagal hunting,it gives local pelope a good economic reason to preserve plants and animals.In Zimbabwe,for instance,there is a sustainable management project to protect elephants.Foreign tourists pay large sums of money to kill these animals for sport.This money is then given to the inhabitants of the area where the hunting takes place.In theory,locals will be encouraged to protect elephants,in stead of hunting them illegally-or allowing others to do so-because of ecnomic benefit involved
