A Habitable Zone is an astronomical term used to described the region of space where conditions are best suited to harbor life that is similar to Earth. Because of our definition of life these zones describe planets that have the ability to maintain liquid water on its surface.

Water / H2O - We can locally destroy our water supplies through the destruction of the desalination systems and not maintaining our sources of water such as reservoirs and dams.
Agriculture / Food Production - We can locally destroy these resources through the overuse of our farmland, thus depleting the nutrition in our fields. We can also deplete natural food ecosystems through overfishing and overhunting specific animals.
Energy Supply - Regardless of what type of…show more content… Figure 1: Describing differences between Autotrophic and Heterotrophic organisms
Decomposers - Organisms which consume the remains the dead consumers and devolve them back into small minerals
Consumers - Organisms who use other organisms to their advantage by consuming their nutrients

Producers, consumers, and decomposers
Ecological Footprint is the overall effect one or multiple humans have on an ecological system. The categories which define it often are food consumption, shelter, energy usage, and overall commute. If everyone had an Ecological Footprint similar to that of an American, we would need 4 earths in order to have a sustainable ecosystem. Currently the global EF is 1.4 earths, and this tells us that we are contributing 40% more negative effects and usage of ecological system can possible
