We enjoy learning about nature--we're fascinated by medical breakthroughs, technological advances and Earth's natural wonders. But there is another side of nature that many people don't like to hear about. Instead of being harmonious and altruistic, this side of nature is a brutal, violent, amoral struggle for existence. Many students who want to learn about life and nature turn away. As Darwin remarked, this fear is a result of man's "arrogance" and vanity.
