Rather than just *liking* Pickle Juice's comments because I agree with them, I guess I should post my own.
Viewed dispassionately, I can't come up with anything that we as a species have done that has had a net positive benefit on the planet or to any species 0ther than our own. In fact, we have had a tremendous net detrimental effect on other species and the planet as a whole.
If anyone can give an example that refutes the preceding paragraph, I'd be interested to hear it.
Based on that, we are indeed like the Guinea worm.
As individuals, we are indeed capable of remarkable acts of altruism*, creativity, etc., just as we are capable of what I would term unimagineable evil but for the fact that some of us apparently can not only imagine it but carry out the acts. For the most part, though, we conveniently turn a blind eye to the effects and consequences of our actions as individuals and as a species.
*Although most of those consist of either helping our own species or trying to counteract the negative effects caused by our own kind.
We could have been like the other large predators at the top of the food chain, killing those of other species who are old, sick, weak, and therby playing a role in keeping other species healthy. But our intelligence and our adaptability and our immense ego resulted in an explosion of our population and a disregard for consequences that has had and continues to have a devastating effect on other species and the planet as a whole.
So, yes, while I like and respect and admire individualmembers of our species, our species as a whole....
