Article: Many groups continued their hunter-gatherer ways of life, although their numbers have continually declined, partly as a result of pressure from growing agricultural and pastoral communities. Many of them reside in the developing world, either in arid regions or tropical forests. Areas that were formerly available to hunter-gatherers wereand continue to beencroached upon by the settlements of agriculturalists. In the resulting competition for land use, hunter-gatherer societies either adopted these practices or moved to other areas. In addition, Jared Diamond has blamed a decline in the availability of wild foods, particularly animal resources. In North and South America, for example, most large mammal species had gone extinct by the end of the Pleistoceneaccording to Diamond, because of overexploitation by humans, although the overkill hypothesis he advocates is strongly contested.[by whom?]

Ans: in the developing world
