Effective Shark Finning Bans Advancing – Hopefully

Efforts to eliminate the cruel practice of shark finning – slashing the fins off captured sharks for financial gain and sending the mutilated sharks to certain, slow death in the oceans – has been a long slog of slow progress, inadequate measures and outright failures.

Whales & Carbon: To Save the World, Save the Whales

As the world ponders ways to capture carbon and combat climate change, think about the idea of whales and carbon storage. During their long lifetimes, great whales takes gargantually more carbon dioxide out of the atmosphere than whole forests of trees – and keep it there. A new study underscores our cetacean cousins’ importance to our planet beyond just oceanic diversity.  GREAT WHALES SWIMMING IN THE OCEANS DON’T SPRING TO MIND AS A SOLUTION TO

Manta Ray Socializing: Mantas Just Want to Hang Out

FAR FROM BEING FREE-RANGING LONERS, MANTA RAYS BOND WITH EACH OTHER in relationships that often last for extended periods, according to a five-year study of manta ray socializing in Indonesia.

The Conch Republic Has Just Banned Coral-Toxic Sunscreens, and So Should You!

THE EVIDENCE IS CLEAR: THE MOST COMMON CHEMICALS FOUND IN SUNSCREENS, OXYBENZONE AND OCTINOXATE, are damaging to coral reefs and contribute to coral bleaching. The city of Key West in Florida has just joined the state of Hawaii in voting to ban the sale of coral-toxic sunscreens.
