Biodiversity and the human past: Lessons for conservation biology

We review human effects on biodiversity using archaeological and ethnographic cases with contrasting ecologies, population densities, and economies. Relevant trends include increasing human populations, settlement sizes, and permanence; intensification of subsistence and political economies; world colonization; and changing environmental values. Although humans have always transformed ecosystems, many pre-industrial societies maintained diverse and stable environments that are now considered natural. Disastrous strategies have resulted from values associated with colonization, market economies, property systems, resource extraction and production technologies, and the isolation of decision-makers from environmental consequences. Present-day solutions should engage decision-making by local communities, especially Indigenous and traditional societies, empowering them to shape policies and achieve conservation goals.
