Sharks are very important in the ocean ecosystem. Like most top predators, sharks feed on the sick and weak, thereby keeping the schools of fish on which they feed healthy. Lions and tigers serve the same role in their respective ecosystems, removing the weaker animals from the herds, and keeping the gene pool strong. Although it has long been said "The only good shark is a dead one," sharks have a very important role in the ocean ecosystem, and they most certainly are not better off dead. Believe it or not, we need sharks in the oceans.
Shark populations are dwindling due to heavy commercial fishing and the general attitude that they are nothing more than a nuisance. This shortsighted view of the ocean ecosystem is dangerous--a shortage of sharks could be disastrous to the health of ocean food chains, including but certainly not limited to the ones we rely upon for food resources. We humans are already placing enough strain on these food chains as it is, without adding the shark to the equation. We must respect these animals and give them the space they need to live. Sharks really are beautiful animals...once you get to know them.
