The geosphere is associated with the states of terrestrial matter: solid (earth), liquid (water), gas (air), and plasma (fire). The atmosphere is a layer of gases that may surround a material body of sufficient mass. The hydrosphere is the collective mass of water found on, under, and over the surface of a planet. Finally, the biosphere is the part of the Earth, including air, land, surface rocks, and water, within which life occurs, and which biotic processes in turn alter or transform. The hydrosphere is essential for life, in that case the biosphere would not be around unless we had the hyrosphere. Plants would also not be able to grow if there were no geosphere, and if there were not plants there would be no life. So, it is essential that we have every one of these major systems. A concern is climate change, such as global warming caused by anthropogenic releases of greenhouse gases, most notably carbon dioxide, and their interactions with humans and the natural environment. I will used this information in the future because now I know that we would not be here unless we had every one of the major systems. We need to changed our ways, like cut down polluion, so that we can keep these. Common good supports this cause I would be doing a good thing for the world, keeping it going. People would argue that it'll be hard to change this much, but it'll be worth it to save the planet.
