Paul, although humans consider themselves to be an intelligent race and have advanced research capabilities, we still know little about the plant and animal world.
If we could fathom the inteligence that certain animals have, like dolphins, whales, and so on, we would treat them with more respect. The opposite is often the case because we do our best to ruin their environment by dumping plastic into the sea (resulting in the so called 'plastic soup' in oceans) and by trying to capture them for various purposes.
