Sustainability and Interdependence

pia08329-earth-browseOur human population is dependent upon sufficient and sustainable food production from the harvest of a narrow range of crop and livestock species. The importance of both plant productivity and the manipulation of genetic diversity in maintaining food security is emphasised. Many individual organisms are also interdependent, whether as symbiotic partners or as members of a social group. Biodiversity studies attempt to catalogue and understand the human impact on patterns of diversity and extinction in our biosphere.
