2 Critically Endangered Right Whales Found Dead, Entangled in Fishing Gear

A study by the New England Aquarium in Boston, released earlier this month, revealed that the critically-endangered whales are threatened by a dramatic increase in lethal entanglements with fishing gear. Only 500 remain in the ocean.
The North Atlantic right whale is one of three right whale species in the world's oceans, the other two being the Pacific right whale and Southern right whale. They are distinct species and do not interbreed. Like blue whales and humpbacks, right whales are baleen whales that get their food by filtering large quantities of water through plates of baleen, which act like a strainer. They can consume more than 2,600 pounds of tiny zooplankton and krill per day.
Right whales have led a hard life for the last 1,000 years. That's when the earliest hunting of whales began, and they owe their name to the notion that they were the "right whale" to hunt. They tend to stay close to the coast and they are slow swimmers. When killed, they float on the surface. As early as the 1700s, the population of right whales became so decimated that they were no longer commercially significant.
The North Atlantic right whale flirted with extinction by the early 20th century, and whaling for this species became illegal in 1935. But almost 60 years later, there were just 295 whales and the population was well below a sustainable level. In the U.S., they were first listed as an endangered species in 1970, but recovery has been slow and uneven. The most recent data from NOAA Fisheries estimates the population at 465 individuals.
As far back as 1990, ship strikes and entanglement with fishing nets were responsible for one-third of right whale deaths. Now, fishing gear is the dominant cause of death for North Atlantic right whales. The New England Aquarium study, published in Frontiers in Marine Science, reveals that from 2010 to 2015, 85 percent of right whale fatalities were due to entanglements. Ship strikes have declined as a percentage of death since shipping lanes in the Bay of Fundy were moved in 2003 and the U.S. lowered ship speed limits in right whale habitats in 2008.
However, efforts to reduce kills from fishing gear have not been successful. Many whales become entangled multiple times, often able to free themselves only to get caught up once more. Young whales become trapped more often than adults. The study's authors echoed a 2016 paper from NOAA Fisheries "that efforts made since 1997 to reduce right whale entanglement have not worked."

Off Provincetown, Massachusetts, last Thursday, rescuers removed 200 feet of fishing gear and buoys, freeing that one lucky right whale. Attached to one of the buoys was a U.S. fishing license. An investigation is under way.
One of the unlucky dead whales found floating near Boothbay Harbor was an 11-year old female, who was only at the very beginning of her reproductive years. She was well known to scientists, having been tracked and spotted 26 times since 2006. In her short life, her travels had taken her to the Florida waters, Cape Cod Bay, the mid-Atlantic and the Gulf of Maine. She died a long, painful death, with rope wrapped around her head, both flippers and in her mouth.

It is now about the time that most North Atlantic right whales head south for the winter. Following a spring and summer off Northern New England and the Canadian Maritime Provinces, they'll head for the warmer waters near Georgia and Florida. There, females may give birth, but do so only once every three to five years.
On Sept. 15, President Obama created the first marine national monument in the Atlantic Ocean. The Northeast Canyons and Seamounts National Monument lies to the southeast of Cape Cod, covering some right whale habitat, but at only 4,913 square miles, it protects only a small triangle of a vast ocean.
The authors of the New England Aquarium study put it plainly: "In conclusion, right whales are not yet a conservation success story."

Jean-Marc Neveu and Olivier Civil never expected to find themselves battling against disposable mask pollution.
When they founded their recycling start-up Plaxtil in 2017, it was textile waste they set their sights on. The project developed a process that turned fabrics into a new recyclable material they describe as "ecological plastic."
Mounting Piles of Waste<p>It is not only the streets of Chatellerault where pandemic pollution is piling-up, but also the world's beaches and oceans. Once there, they can take up to 450 years to degrade and disappear.</p><p>Esther Röling, co-organizer of the annual Adventure Clean Up Challenge held on Hong Kong Island, has seen this waste firsthand. In October the sports challenge pitted teams against one another in a competition to remove trash from 13 hard-to-reach coastal areas around the city.</p><p>They find tons of both disposable and reusable masks, said Röling. "You wonder how it ended up there. Was it just thrown on the ground? Or was it in a garbage bag that broke open?"</p><p>Almost 10,000 kilometers away in Antibes on the sunny French Riviera, it's a similar picture. For the past few months, divers and clean-up volunteers working with an ocean clean-up non-profit called Operation Mer Propre have been collecting an increasing number of masks found on land and in the sea.</p><p>"Since the beginning of the lockdown when we started to count, we've reached 800, 900, [and now in total] 1000 masks," said co-founder Joko Peltier. </p><p>According to <a href="https://unctad.org/news/growing-plastic-pollution-wake-covid-19-how-trade-policy-can-help" target="_blank">UN estimates</a>, up to 75% of all coronavirus-related plastic could end up as waste in oceans and landfills.</p>
The Limits of Recycling<p>Yet not all are convinced the recycling of this waste is possible on a global scale. </p><p>"What those citizen groups are doing is really beneficial but once they collect it, it should just go to a landfill or an incinerator. They shouldn't necessarily expect it to get recycled," said Jonathan Krones, an industrial ecologist and visiting assistant professor of environmental studies at Boston College.</p><p>That's because mask recycling programs like Plaxtil are few and far between and most don't have the benefit of a readily adaptable production process. </p><p>Even in countries with solid recycling infrastructure, he says, the system is designed to separate out specific types of waste like bottles or cardboard.</p><p>"I imagine that it would be technically feasible to develop a separation process to filter out masks, but there simply aren't enough of them to make that economical," he said.</p><p>Collection is a big hurdle, he adds. Since each mask only weighs a fraction of a gram and they're scattered on roads or mixed with other trash, it is difficult and costly. </p><p>"You need a lot of raw material of the right quality to make investing in the recycling technology and the recycling system worthwhile," he said.<span></span><br></p>
Hemp, Sugar Cane and Sustainable Alternatives<p>Some projects are instead addressing the material used to make masks.</p><p>French company Geochanvre have created a mask made primarily from hemp, while in Australia, researchers at the Queensland University of Technology are experimenting with a disposable product made from agricultural waste. </p><p>Biodegradable options are exciting alternatives to reduce the fossil fuels needed for the creation of plastic-based masks, said Krones, but they don't absolve the wearer from the responsibility of what happens afterwards. </p><p>Bio-based masks often need their own composing solutions, he explains, because in landfill they can produce high amounts of the greenhouse gas methane when anaerobic bacteria feeds on the organic material. Methane is known to be significantly more potent than carbon dioxide.</p><p>"I think as long as we have in our mind that we want to have disposability, we're going to have to wrestle with a variety of different sorts of environmental tradeoffs," he said, adding that reusable, fabric masks are the best option available to most people.</p><p>Precimask is developing a clear face covering with an optional visor made from hard plastic, designed to be long-lasting.<br></p><p>Air enters either side of the cheeks through a technology normally found in pool filters and car exhaust systems, said company spokeswoman Juliette Chambet.</p><p>"We wanted to make ceramic-based filters that would be washable and cleanable, which would allow them to be reused as many times as desired without having to buy a new consumable or produce waste," she said. </p><p>Ultimately, encouraging mask wearers to think about the entire lifecycle of a mask is key, explains Neveu. </p><p>"We want people who put on the masks to realize that they are also responsible for the waste, he said. "It's not inevitable that this [pandemic] will become an environmental catastrophe.</p><p><em>Reposted with permission from </em><em><a href="https://www.dw.com/en/covid-19-recycling-pollution-trash-pandemic/a-55707817" target="_blank">Deutsche Welle</a>.</em><a href="https://www.ecowatch.com/r/entryeditor/2649032193#/" target="_self"></a></p>
