Ancient Extinctions: Megafauna
Some may underestimate the influence of humans on ecosystems such as the one found in Australia's Outback. We can see from history, however, that this idea is without merit. Paul Martin's overkill hypothesis presents evidence that humans have historically been the cause of extinctions for many large animals (megafauna) throughout the entire world (Mosimann 304). In Australia in particular, evidence suggests that megafauna such as Procoptodon Goliah (the largest kangaroo to exist) were eaten by humans into extinction. Presently, it is important for humans to understand that importance of keeping ecosystems healthy so as to preserve diversity.
The Example of the Aboriginals
The destructive force humans have on new areas can not only affect animals and plant life, but also other humans. The aboriginal natives, indigenous to the lands of Australia for thousands of years, were negatively affected by the entry of Westerners into the Outback. Westerners, who often thought of these natives as backward and uncivilized, caused the massive decrease and dispersion of aboriginal populations.
