(From kpbs.org)- A new study says sharks are necessary for healthy oceans, but commercial fishing is taking a toll on their populations. Each year, tens of millions of sharks are caught only for their fins. Sharks have been swimming in the world”s oceans before dinosaurs roamed the Earth. But whether they”re still around in the next century is in doubt.
