Ocean acidification is one of the most important issues regarding climate change, but what is it, really? How does it affect our oceans' health, and what does it mean to you and I? Get the scoop on what you need to know about it, with help from a senior scientist at the National Resources Defense Council.

The team from Planet 100 brings you a crash course in ocean acidification. It's the basics of everything you need to know -- from what it is and what causes it to it's impact on oceans, people, and our planet and what we can do to stop it -- all in video form.

Last year, Planet Green premiered "Acid Test," a striking documentary hosted by Sigourney Weaver, about the challenges we face with global ocean acidification. Get caught up on the film with this video playlist, including some behind-the-scenes extras.

Test your smarts on ocean science, fishing, climate change, acidification, and more in our interactive quiz.

Bob Woodruff and Focus Earth take a closer look at coral reefs at the World Ocean Conference, and the news isn't all good. Our coral reefs are in trouble, but it doesn't have to be that way.

The health of our oceans' coral reefs and ocean acidification are closely tied. Learn what it's going to take to save the coral reefs and keep our oceans healthy.

Connect the dots between the ocean's biggest predator -- sharks -- and the health of one of the earth's biggest ecosystems -- coral. It turns out that more sharks can equal better coral health around the globe.

Take a closer look at the Great Barrier Reef in Australia, where the perfect combination of weather and geology have created the perfect location for coral to grow and thrive.
