"Under the rules of the Endangered Species Act, once a species is discovered to be at risk of extinction, government agencies are required by law to take steps to save it. For years, critics have challenged that mandate, arguing that it undercuts the ability to weigh a species’ value or to consider the economic impact of its preservation — for instance, the cost of prohibiting logging in a valuable tract of forest. Since Donald Trump took office, these objections have gained ground; there are currently six bills pending in Congress, all aimed at overhauling (some would say gutting) the Endangered Species Act."

"Krill oil, rich in heart-healthy omega-3 fatty acids, is a popular nutritional supplement around the world. However, according to a recent report from Greenpeace, growing demand is fueling commercial fishing in Antarctica’s icy waters that could make it harder for all kinds of polar marine life to survive climate change threats."

"Picturing the England’s coastlines, you might imagine the White Cliffs of Dover, jaunty seaside towns with colorful beach huts, or colonies of seals or puffins and the odd killer whale. Yet nestled in these shorelines are well over 1,000 disused landfills poised to begin shedding their contents—plastic, metal, household waste, and organic contaminants—onto beaches and into the sea."

"There is concern that attaching the wrong word to the problem could result in the wrong management decisions to fix it. The problem, the fishers say, is not how many salmon are being caught but the number of newly born juveniles that even make it to the ocean in the first place – and at the root of that issue is upstream water conditions."
"Scientists have engineered bacteria to produce a key ingredient found in environmentally friendly sunscreens. The advance, reported in the journal ACS Synthetic Biology, could speed up the production of green sunscreens and make them more affordable."
"City life may suit the world’s largest octopus species, according to a new study from researchers in Seattle. The study is a rare look at how urbanization affects marine organisms. It suggests that the sea, too, has its synanthropes – wild species that live in, and even benefit from, human-dominated landscapes."
"Since then, much scientific research has focused on the presence of giant kelp and the range of biodiversity it supports. Many marine biologists think of the world's biggest alga as the keystone species of its ecosystem, not only in terms of its structure—a huge forestlike environment under the sea—but also in terms of its tremendous productivity in supplying food for the near-shore ecosystem."

"Typically, one bite is all a shark takes to kill a sea otter. For a white shark looking for blubber-rich seals, a sea otter is just an unappetizing hairball. But to the otters, the sharks’ intentions are irrelevant—they still end up dead, or wounded and in need of rehabilitation."

"Water use rights and access vary by region across the country, though the water itself has always been a public resource for people to fish, paddle, wade and float in. Private landowners have long taken unsanctioned steps to keep the public out of waterways, as in the recent case of an Arizona man convicted of shooting at kayakers boating down a river that runs through his land."
