Indonesia’s First Shark Sanctuary – Raja Ampat Leads the Way

This week has without a doubt been the highlight of my career as a marine conservationist. And, as someone who has had a long-term love affair with the world’s oceans, it’s been a life highlight as well.

On 20 February 2013, the Raja Ampat government officially announced that it has declared its entire 4 million hectares of coastal and marine waters a shark sanctuary.

This means that all harvesting of sharks is now prohibited in its waters. In addition, the sanctuary also gives full protection to a number ecologically and economically important ocean species, such as manta rays, dugongs, whales, turtles, dolphins and ornamental fish species.

Why is this important and why should we care?

Well, sharks have a really hard time in our oceans. Beyond the often over-amplified fear people have of sharks, they are also targeted for their high-priced fins or are caught accidently in fishing nets.

It is estimated that at least 26-73 million sharks are killed each year globally, mostly for their fins. Shark finning is one of the cruelest practices around—it involves throwing a still-breathing shark overboard with its fins cut off and its body bleeding into the water.

Oceans and Climate Change: Protecting the “Invisible”

Coral bleaching, increasing storms, the loss of polar bears: many impacts of climate change are already vivid in our minds. We naturally worry about the things we can see. Huge waves and the loss of big fish and colorful corals get our attention.

But what about things we can’t see, like the tiny creatures called plankton? They are also poised for dramatic changes.

A recent dive in the sapphire waters of the Caribbean offers a close encounter with plankton. While most of my dive buddies hurry to reach the bottom, I linger as I usually do, pondering the “blue” and looking out for the visible and the invisible.

Suddenly, clouds of tiny filaments come sharply into focus. It’s blue-green algae–Trichodesmium–a type of phytoplankton that plays an important role in these nutrient-poor waters. They essentially break gaseous nitrogen’s tough triple bond and convert it into a form other phytoplankton can feed on.

What would these waters look like without them?
