Whale Sharks Move onto the Endangered List

Posted On August 30, 2016 by

Written by Dr. Alistair Dove

You may have seen in the press the recent announcement from the International Union for the Conservation of Nature, that whale sharks (along with the enigmatic wing head shark) have been downgraded from Vulnerable to Endangered on the IUCN Red List.  I thought it might help to explain exactly what that means, so I’ve done it as a sort of Frequently Asked Questions (FAQ):

What’s “the IUCN Red List”?
The Red List is a sort of master-file about the conservation status of different species.  As you can see from the screen capture below, the ranking goes from Least Concern (LC) for really common species, all the way down to Extinct (EX), with a couple of other categories for species that haven’t been evaluated (Not Evaluated NE) or that were evaluated but there wasn’t enough scientific data to decide on a status (Data Deficient DD).  All of these levels are recoverable, except for Extinct (EX); there ain’t no coming back from gone.

When Doing the Right Thing is Also Fun!

Posted On August 29, 2016 by

By Chef Kyle Bailey

Doing the right thing can also be fun. For chefs like me, working within the limits required under U.S. sustainable fisheries management law these last ten years hasn’t been a burden, it’s been a bonanza.

Prior to 2006, when overfishing was still rampant in U.S. waters, the fishermen I buy from would often bemoan the fact that they didn’t have Atlantic cod, bluefin tuna or swordfish—the fish species American cuisine had grown to rely on. In other words, no fish and chips, no tuna sushi and no swordfish steak would be on the menu that night.

The Problem of Ocean Trash

Posted On August 22, 2016 by

Written by Tori Glascock

Each year an estimated 8 million metric tons, or 17 billion pounds, of plastic flows into the ocean. Enough is enough.

First and foremost, an endless flow of trash into the ocean will affect the health of humans and wildlife alike as well as compromise the livelihoods that depend on a healthy ocean. Trash and debris such as fishing gear, straws, and plastic bags pose a deadly threat to marine life. Fishing gear can trap helpless sea turtles and cut through flesh of whales, while plastic bags are easily mistaken as food and consumed by animals. Straws can be hazardous in that they can get stuck in a nostril, a blowhole, an eye, or even a throat.

Fight Back Against Marine Debris

Posted On August 18, 2016 by

Written by Senator Cory Booker

Every 60 seconds, what amounts to roughly a garbage truck full of plastic makes its way into the ocean.  That means that over the next year about 8 million tons of plastic will enter the ocean, creating a massive amount of marine pollution.

It’s estimated that if we don’t do anything to address this source of pollution, there will be one pound of plastic for every three pounds of fish in the ocean by 2025.

Preventing further damage to our oceans will require a coordinated global effort, and the United States has a vital role to play in leading this charge.

Last month, 2,500 people from 97 countries flew to Hawaii–not for vacation, but to address the international crisis facing coral reefs around the world.

Participating in the 13th International Coral Reef Symposium, these world leaders, scientists, activists and students issued a powerful call to action to address the growing threat of coral bleaching around the world.

Tackling Ocean Acidification in Florida

Posted On July 6, 2016 by

As the state representative for the Florida Keys and South Miami-Dade County, there are few things more important to our well-being than the health of our unique marine environment. We are home to the Everglades, the 3rd largest barrier reef in the world and the only living barrier reef in the continental United States. Since I took office, I have made it a priority to do everything I can to help raise awareness about our water issues in Tallahassee and we’ve made great progress in the last four years when it comes to improving water quality.

Despite this progress, there are still many stressors facing Florida’s oceans and ocean acidification (OA) is a particularly significant threat. Its impacts on our marine ecosystems are less visible so it has not been as widely discussed as other environmental threats, but that is starting to change, and I am excited to help bring further awareness to this issue. Side effects of acidification like decreases in coral reproduction, growth and calcification as well as slower shellfish growth mean that this is not an issue we can afford to ignore. Already, other fisheries across the country are seeing serious economic impacts from OA and if it continues unchecked, the impacts to Florida businesses and residents could be equally devastating.

Poles Apart: The Differences between Antarctica and the Arctic

Posted On June 30, 2016 by

This blog was written by Roger Di Silvestro, a field correspondent for Ocean Conservancy.

Have you ever seen a cartoon or advertisement that showed penguins and polar bears cavorting together in the snow?

On the flip side, have you ever seen a documentary film that showed penguins and polar bears together in the wild? Didn’t think so, since they live poles apart. Nevertheless, not everyone (advertisers included) understands the difference between Antarctica and the Arctic. Here are eight ways to tell them apart.
