Yes, but we're probably doing a reasonably fair job of that anyway......without the help of some kind of disease. Even without the Bigfoot or any other creature to worry about, we're paying a pretty heavy price for our greed and consumption. In truth, we shouldn't be depending on proving the Bigfoot's existence to start saving and protecting our wild habitats. If the creature's elusiveness has taught us anything, it should be that little piece of reality.
