Ecosystem: All organisms (biotic) particular place; includes nonliving (abiotic) surroundings of areas. Biome: Group of ecosystems with the same climate (temperature and precipitation) and similar communities. Biosphere: All portions of the planet where life exists (land, water, air, atmosphere).

Environmental Science Offers Important Insights Into Our World & How We Influence It: -

Fracking: Hydraulic Fracture for CH₄ (Methane/natural gas) o Not conclusively linked to ground water contamination. o Linked to methane leaks into the atmosphere o Uses an exhaustive amount of water (treated water)

-
