This is a population issue. When the human population was much smaller humans and wildlife could easily coexist. That is not the case anymore. The article above mentions the Maasai, who have a rapidly growing population and are poisoning all the lions in their area in order to avoid livestock predation. Tigers are disappearing because humans are encroaching on their dwindling habitat and won't tolerate tiger predation. Asian elephants are threatened with extinction because humans are clearing forest, planting crops, and then shooting elephants when they eat the crops. Large predators, great apes, and elephants need large areas without human interference. Romantacizing about indigoneous people living in harmony with wildlife doesn't work.
