New Species Of Shark Discovered

A new species of shark has been discovered in the waters off South Carolina and apparently only breeds in those waters. It is similar to the scalloped hammerhead. Neat! Of course, almost as soon as it was discovered it became "endangered." From BBC News:

US researchers say the animal appears to be rare, breeding only in waters off the South Carolina coast.

They believe the shark is at risk of extinction and conservation efforts are needed to protect females when they are raising their pups.

My question: why do we need to protect it? Good grief! Species go extinct for a reason. Not every idea that evolution comes up with works, and we simply can't protect every species we encounter. Maybe this species has become "too" specialized in its breeding habits. We should just study it, catalogue it, and let nature take its course. Anything else is just sticking our noses in where they don't belong.
