Using the Species-Area relationship (Williams, C.B.) as a rough reference, one can attest to a certain degree the amount of time left for a given amount of species suffering from habitat loss. By taking into account the geographic range and population density within the specied geography, we can correlate the data with a specific timeframe. While most of the species may still have a few years left in their existance, some species that already have become extinct were included in the diagram in order to highlight the importance of protecting endagered species.
