Ecology considers organisms at the individual, population , community , ecosystems , and biosphere level. Ecology overlaps with the closely related sciences of biogeography , evolutionary biology , genetics , ethology and natural history. Ecology is a branch of knowledge, and it is not synonymous with environmentalism. Ecology has practical applications in conservation biology , wetland management, natural resource management agroecology , agriculture , forestry , agroforestry , fisheries , city planning urban ecology , community health , economics , basic and applied science , and human social interaction human ecology. Evolutionary concepts relating to adaptation and natural selection are cornerstones of modern ecological theory.
Scientists have been warning for decades that human actions are pushing life on our shared planet toward mass extinction. Such extinction events have occurred five times in the past, but a bold new paper finds that this time would be fundamentally different. Scientists count just five mass extinctions in an unimaginably long expanse of million years, but they warn we may well be entering a sixth. According to a bold new paper in The Anthropocene Review , this time would be different from past mass extinctions in four crucial ways — and all of these stem from the impact of a single species that arrived on the scene just , years ago: Homo sapiens.
