Plastics in Seabirds: A Pervasive and Growing Problem That Requires Global Action

Posted On August 31, 2015 by

You have likely seen the pictures of albatross chicks chocking on plastics. These images are tough to look at and the death these birds suffer from ingesting plastics is gruesome and painful. Albatross consume a whole range of plastics that float in the ocean, from cigarette lighters, to toothbrushes to shards of plastics from a huge variety of other plastic products. As a conservation organization, Ocean Conservancy is deeply troubled by the impact of plastics on these magnificent birds. But how pervasive is this problem, really? A new paper in the peer-reviewed journal PNAS gives us a disturbing answer. It turns out plastics in seabirds is a very big deal. It is global, pervasive and increasing. And it has to be stopped.

Take Action to Help Save Whale Sharks

Posted On July 10, 2015 by

The largest fish in the ocean is one of the most majestic, too: the whale shark. These gentle giants are also in danger.

Right now, there’s a very simple way to protect them, and you can help. Off the coast of Mexico, thousands of whale sharks gather to feed and mate every year. Unfortunately, there are two cruise ship companies whose cruises currently travel through this important area where whale sharks congregate in large numbers and swim slowly at the surface of the water.

The beauty of this area is bringing more and more visitors each year, and unfortunately, they are having some negative effects on the whale sharks. There is an easy step to be taken in protecting whale sharks in this region, and we hope you’ll take just a moment to let Carnival and Royal Caribbean Cruises know how important it is to you that they adjust their course by 7 miles to protect these magnificent animals.

Saving the Oceans from Plastic: A Field Report from Belize

Posted On May 20, 2015 by

Some people would call Belize paradise.  Having recently returned, I can’t say I disagree, but I also saw threats to the beauty on the surface. I spent a week in Belize researching the connection between waste management, plastic pollution and ocean health in this Central American country. As Chief Scientist, I’m working closely with our Trash Free Seas® team to build on our 30-year history of protecting our ocean from the growing threat of ocean trash.

I toured much of the country with independent consultant Ted Siegler from DSM Environmental Services, gaining a firsthand perspective on how recent investments in waste management systems in Belize are improving ocean health but learning how much farther the country needs to go. A former British colony, Belize is frequented by tourists for its beautiful beaches and tropical breezes. But Ted and I visited many sights never seen by these outsiders. The upshot? Trash is a major problem in Belize, as it is in many developing countries.  And it is increasingly clear that this has big consequences for the health of the ocean.

Good News for the World’s Smallest Porpoise

Posted On March 9, 2015 by

Good news for vaquitas this week! The Mexican government will ban the use of gillnets in the Gulf of California, the only place vaquitas call home, for the next two years. This is a much-needed protection for the critically endangered vaquita. In fact, there are less than 100 left in the world.

This is a vital first step in rebuilding the population of the world’s smallest porpoise. Vaquitas are often caught as bycatch in gillnets, which ensnare and kill them.

Trashing the Ocean: New Study Provides First Estimate of How Much Plastic Flows into the Ocean

Posted On February 13, 2015 by

8 million metric tons. That’s 17 billion pounds. That’s a big number. It’s also the amount of plastics that scientists have now estimated flow into the ocean every year from 192 countries with coastal access.

A groundbreaking study was published yesterday in the international journal Science and released at the annual meeting of the American Association for the Advancement for Science in San Jose, California. This work is part of an ongoing international collaboration among scientists at the National Center for Ecological Analysis and Synthesis (NCEAS) at the University of California, Santa Barbara to determine the scale, scope and impacts of marine debris – including plastics – on the health of the global ocean. Spearheaded by Dr. Jenna Jambeck, an environmental engineer from the University of Georgia, and other experts in oceanography, waste management and materials science, this is the first study to rigorously estimate the flow of plastic materials into the global ocean.

For the last decade, scientific evidence has been mounting that once plastic enters the ocean it can threaten a wide diversity of marine life (from the smallest of plankton to the largest of whales) through entanglement, ingestion or contamination. The images of how plastics kill wildlife aren’t pretty. But if we are going to stop this onslaught we must know how much material is entering and from where.

Petition: Save the Vaquita

Posted On August 23, 2014 by

The smallest porpoise in the ocean is facing the biggest chance of extinction. With fewer than 100 remaining, the vaquita, a tiny porpoise found only off the coast of Mexico, is the most endangered marine mammal in the world.

The few remaining vaquitas need your help, now!

Sign the Petition: Save the vaquita from extinction!

Imagine losing this species, entirely. The tiny vaquita seems to always be seen smiling, but those smiles are depleting. This swift decline of the population is a direct result of fishing nets. These vaquitas are getting caught in nets, and dying completely preventable deaths.

This is a First For Sharks

Posted On August 13, 2014 by

Happy Shark Week! We have some shark news to share with you — help is on the way for scalloped hammerhead sharks! Will you join us in thanking the National Oceanic and Atmospheric Administration (NOAA) for helping these sharks by granting them protection under the Endangered Species Act.

Thank NOAA today for protecting endangered scalloped hammerheads.
