I apologize if this answer seems a bit rushed, but I didn't want it to take up too much space.
Our environment has suffered greatly as consequences to our actions. Our insatiable hunger for more land and the overpopulation of our world has brought about the extinction of various animals and plants, as well as several cultures having been forgotten through modernization. Not only can we not preserve our own race, but we see these problems and disregard them completely. Our ignorance, our selfishness, and our destructive nature has changed Earth for the worse, and few seem to be taking action to reverse these effects.
I developed my paragraph by bringing up how much Earth has changed through our actions, the contrasts becoming evident throughout.
