We have learned more about our environment and planet as science has progressed. In addition, scientists have done more experimenting and more hypothesizing to figure out even more about the world. We have learned a lot about this blue marble, but we still do not know everything yet. This is why scientists make theories; to learn more about the universe around them and give educated guesses as to why something happens. One of these theories is the Gaia Theory. The Gaia Theory states that the earth is a living organism just like you and me. All living creatures contain cells to maintain bodily functions. This is exceptionally true to Earth. If the earth is one big organism, then we are the cells of this organism. All animals and plants are cells of earth. The tissues are larger places such as forests or maybe even cities. Every living organism has some role on earth. This role is classified scientifically as a niche. Cells have a niche as well inside of our bodies. They each have their own special jobs- some delete pathogens, some regulate temperature and some transport material, etc. Their environment is us, the organism. The earth has bodily functions like us as well- The tides of the earth, the natural disasters occuring lately, etc. Everything that happens on our planet happens for a reason. Some natural disasters occur as an example of negative feedback- in our bodies, we sometimes get fevers when the body temperature rises to get rid of our invaders. The same can be applied to Earth. We humans sleep and eat while the earth is such an advanced organism that it does not need to eat or sleep. The earth, is in a way immortal, yet mortal. It has an incredibly long lifespan. The earth is dependent on something just as we are to continue living. The earth depends on the sun, to nourish us, the cells, so that we may live further as well. When an organism is lacking in cells or has a mass amount damaged, the body suffers as a result. When something bad such as a stomachache happens, the entire body feels it. The same principle applies to if we kill life on earth- We damage a part of the earth, then the whole earth suffers. One example of this is destroying the environment- if we tear down rainforests and spread pollution, then the whole earth suffers- The flux of life on the earth is changed. The flux of life within us is the same as the flux of life on earth. This is the Gaia Theory- This is Mother Earth.
