Turning the Tide on Deep Sea Destruction

To truly convey what’s at stake in these unique deep-sea ecosystems, the Pew Environment Group recently put together a short video featuring many visually-stunning images of deep-sea life, as well as the barren aftermath left by high-seas bottom trawlers that have dragged their heavy nets and weights across the ocean floor. Scientists attest that this fishing method is the single most destructive fishing activity currently occurring on the high seas.

Ocean Ecosystem Services Can Increase — But Only if We Take Less

National Geographic Fellow Enric Sala comments on a new study, released today, which shows that 75 percent of the world’s coral reefs are threatened by human overpopulation.

The impact of humanity reduces the biodiversity of reef fishes, which in turn has a negative impact on the many services the reefs provide to humans.
