Oil Spills Can Disrupt Entire Aquatic Food Web, New Study Shows

From dead fish to beaches covered in sludge, the immediate damage from an oil spill is easy to see.

But a new study, published this week in the journal Archives of Environmental Contamination and Toxicology (AECT), found that the damage caused by these spills are much wider in scope and can indirectly disrupt the entire aquatic food web.


The 2010 Deepwater Horizon oil spill, which released 134 million gallons of oil into the Gulf of Mexico, killed thousands of marine mammals and contaminated their habitats.

But researchers in the AECT study found that the mass mortalities also led to a dramatic spike in forage fish populations such as menhaden in the years after the blowout.

Menhaden are tiny fish that are prey to a wide range of marine predators such as larger fish, birds and cetaceans such as fin whales and dolphins. With many of their predators gone, these tiny fish were able to quickly multiply.

According to the study, "these releases from predation led to an increase of Gulf menhaden biomass in 2011 to 2.4 million t, or more than twice the average biomass of 1.1 million t for the decade prior to 2010."

"Our discovery suggests that the structure of food webs change after an oil spill, which may be much more damaging to fish and other aquatic fauna than the direct impacts of the spilled oil itself," explained lead researcher Jeffrey Short.

The new analysis "underscores the need to study not just those species obviously affected, but also the entire food web, during oil spill assessments," a press release for the study states.

"While the direct effects of oil spills on ecosystems have been well documented, this new study following the Deepwater Horizon blowout in 2011 provides the first indication that oil spills can alter the nature of entire aquatic food webs," said Peter S. Ross, editor-in-chief of AECT.

Slaughter of 90,000 Wild Horses Could Proceed Despite 80% Objection From American Public

The American Wild Horse Campaign on Thursday harshly criticized Interior Sec. Ryan Zinke's appointment of Brian Steed, the former chief of staff for U.S. Rep. Chris Stewart (R-UT), as the acting director of the Bureau of Land Management (BLM) as dangerous and out of step with the wishes of the vast majority of Americans.

"Rep. Stewart is leading the charge to slaughter America's wild horses and burros over the opposition of 80 percent of Americans," said Suzanne Roy, AWHC Executive Director. "Putting his deputy at the helm of the agency charged with protecting these national icons is like putting the wolf in charge of the chicken coop."

Bright Idea: This Lamp Harvests Its Own Energy From Plants

Now that's green energy. Dutch product designer Ermi van Oers and her team are working on the first atmospheric lamp powered by living plants.

The Living Light does not require an electric socket. It can harvest its own energy through the photosynthetic process of the encased plant, which means the potential of this off-grid light source could be "huge," as Van Oers told Dezeen.

Pope Francis: These 4 'Perverse Attitudes' Could Push Earth to Its Brink

Pope Francis issued a strong message to negotiators at the COP23 climate talks in Bonn, Germany on Thursday, warning them not to fall into "four perverse attitudes" regarding the future of the planet—"denial, indifference, resignation and trust in inadequate solutions."

Francis, who has long pressed for strong climate action and wrote his 2015 encyclical on the environment, renewed his "urgent call" for renewed dialogue "on how we are building the future of the planet."

Groups Sue Norway Over Failure to Protect Environment for Future Generations

By David Leestma

Greenpeace and the Nature and Youth environmental group opened a lawsuit this week over Norway's failure to abide by its constitutional obligation to safeguard the environment for future generations.

The lawsuit, which focuses on local environmental damage and the contribution that oil extraction will make to climate change, challenges 10 licenses issued by the Norwegian government for exploration in the Barents Sea. Given to Statoil, Chevron and other oil companies, the licenses violate Norway's constitution and the Paris agreement, according to the plaintiffs. Government lawyers claim the case is a publicity stunt that risks valuable jobs.

A Plea for Kelp: These Farmers and Chefs Want to Make Seaweed the Next Superfood

By Sarah Bedolfe

Summer in southeast Alaska is kelp season for the cofounders of Barnacle Foods, Lia Heifetz and Matt Kern. Each week, the pair watches the tides and weather, waiting for the right moment to cruise out to the abundant kelp beds offshore. They lean over the side of the boat and pull up the fronds and stalks, one piece at a time. As soon as they get back to shore, they start processing the day's harvest into a local delicacy: kelp salsa.

Salsa and Alaskan algae might seem like odd bedfellows, but for Barnacle Foods, it's a calculated decision. The kelp's savory notes make the salsa's flavor "a little more explosive," according to Kern. And the pairing is also a practical one. "Salsa is such a familiar food item," Heifetz said. It's "a gateway to getting more people to eat seaweed."

Massive Pipeline Leak Shows Why Nebraska Should Reject Keystone XL

About 210,000 gallons (5,000 barrels) of oil leaked Thursday from TransCanada's Keystone oil pipeline near Amherst, South Dakota, drawing fierce outcry from pipeline opponents.

The leak, the largest spill to date in South Dakota, comes just days before Nebraska regulators decide on whether its controversial sister project—the Keystone XL (KXL) Pipeline—will go forward.
