Biogeochemical cycle

thumb|Capitalism imposes its laws of motion on the environment, irrespective of the biogeochemical cycles of the planet and the earth’s metabolism. ~ John Bellamy Foster In geography and Earth science, a biogeochemical cycle or substance turnover or cycling of substances is a pathway by which a chemical substance moves through biotic (biosphere) and abiotic (lithosphere, atmosphere, and hydrosphere) compartments of Earth. Quotes Capitalism imposes its laws of motion on the environment, irrespective of the biogeochemical cycles of the planet and the earth’s metabolism, so that it creates rifts or ruptures in the biogeochemical cycles of the Earth system, disrupting ecosystem relations in ways that transcend the mere scale-effects of economic growth. It is this problem of the metabolic rift that is our deepest challenge. Sustainability is more and more compromised at ever higher levels—a continually accelerating threat to civilization and life itself. John Bellamy Foster, as quoted in A Resistance Movement for the Planet - Full Interview (July 02, 2017), Left Voice. External links Category:Environment Category:Chemistry Category:Geography
