Nature, red in tooth and claw. That line from Tennyson's poem still strikes a chord when we contemplate the natural world. Today, there's a divide in how we view nature. On the one hand, we swing through it like a playground, on the other, we're forced to step back to allow for nature's power in the form of giant waves, rogue tigers, or a simple pet ferret. In this hour of To the Best of Our Knowledge, we come face to face with nature in full force.
