Document Summary
Small populations of hunter-gatherers sought food (result of solar energy) Larger populations of industrialists created food (plants, inorganic fertilizers, animals, growth hormones, chemical preservatives, food colourings, artificial flavours, etc. : began to ship food out. We know humans are releasing unimaginable amounts of carbon to the atmosphere which was sequestered permanently by nature in the form of solid rock (limestone and coal) or liquid (oil) or gas (natural gas). There is (cid:374)o pla(cid:272)e o(cid:374) earth that (cid:449)e ha(cid:448)e(cid:374)"t tou(cid:272)hed. Explain the affects of legacy and recently introduced contaminants on life in the arctic. To make a solution you need to understand how the system works. Biophysical environment has not changed much with human interestion: starting with the energy in each spheres, how have we transformed the circulation and chemical composition of these spheres. Anything we do affects all of them passing of water, change in landscape to build roads. Circulation of the atmosphere, hydrosphere and lithosphere requires energy.
