Ocean acidification may have been involved in a mass extinction 200 million years ago that killed off half of the marine life on Earth. And we know that our oceans today are becoming more acidic by the minute. So the natural questions to ask are: What is going to happen next and what can we do about it?

"We don't know what's going on in our oceans, which is the scary part," said Peter Diamandis, CEO of XPRIZE, on "CBS This Morning." "Because what we do in the next 10 years affects what happens in the next 10,00 years. Unless you can measure something, you can't change it."

And that's why Diamandis just awarded the $2 million Wendy Schmidt Ocean Health XPRIZE to a team from Montana that figured out how to cheaply and reliably measure the pH of the sea. More >>
