Laguna Niguel: protected by the surf industry

The Surf Industry Manufacturers Association (SIMA) has raised more than $6.2 million for environmental groups, in the past 23 years.

The official working trade association of more than 300 surf industry suppliers, founded in 1989, has been supporting organizations that protect the world's oceans, beaches and waves.

The 23rd Annual Waterman’s Weekend, held at the Ritz-Carlton, in Laguna Niguel, raised more than $400,000 to help defend surf breaks locally in Orange County and around the world.

"This year, we are extremely honored to pay tribute to Shane Dorian, Jean-Michel Cousteau and the much loved, late Sean Collins as they are members of our tribe who have helped change the face of our sport, industry and ocean environment", explains Paul Naude, SIMA Environmental Fund President.

Pacific Northwest: 21 coastal spots have caffeine

The Pacific Northwest may be the epicenter of U.S. coffee culture, and now a new study shows the region's elevated caffeine levels don't stop at the shoreline.

After taking samples from 21 spots along the coast, researchers expected to find the most caffeine pollution in areas near wastewater treatment plants, large population centers or rivers and streams emptying into the ocean.

Instead, they found high caffeine levels near areas not near the potential pollution sources — and low levels of caffeine near large population centers.

Coral: acidity plays a crucial role in reefs

Rising acid levels in the world's oceans have emerged as one of the biggest threats to coral reefs, acting as the "osteoporosis of the sea" and threatening everything from food security to tourism to livelihoods.

Oceans absorb excess carbon dioxide in the atmosphere, leading to an increase in acidity. Scientists are worried about how that increase will affect sea life, particularly reefs, as higher acid levels make it tough for coral skeletons to form.

Not convinced that this is a big deal? World Resources Institute has created a great short video that explains what coral reefs are, why they're so important, and the threats we're posing to their health.
