Beloved Orca Found Dead Due to Entanglement in Fishing Gear
This time, an adult female killer whale named Lulu was found dead on Jan. 3 on the Scottish island of Tiree with deep lesions on her body. After a necropsy was performed, experts with the Scottish Marine Animal Strandings Scheme concluded that Lulu had been "chronically entangled" in abandoned fishing gear for several days and likely drowned from entanglement.
Sadly, as many local reports have pointed out, the death of the whale has put the future of the United Kingdom’s orca population in peril.
The BBC reported that Lulu was a member of Britain's only known resident population of the mammals. Now, there may be only eight remaining individuals in the killer whale's pod.
Dr. Conor Ryan, the trust's sighting and stranding officer, said in a statement: “It is particularly sad to know that another one of these killer whales, unique to the British and Irish Isles, has died. There may be as few as eight individuals remaining in this population, which has not produced calves since studies began.”

The Scottish Marine Animal Strandings Scheme conducted an examination of Lulu four days after she was found dead. The organization posted the results of the necropsy onto their Facebook page on Jan. 6, and wrote in graphic detail about the "tragic" circumstances of her death.
Because Lulu was found with deep lesions on her body—perhaps from fishing gear, ghost nets or marine debris—the experts concluded that she might have drowned due to entanglement in the equipment. Here is the Scottish Marine Animal Strandings Scheme's Facebook post:
A very unfortunate but interesting first necropsy for 2016. We’re out on the Isle of Tiree at the moment having necropsied an adult female killer whale (Orcinus orca). This animal has been identified as ‘Lulu’, one of the animals from the Scottish west coast community. By the time we had heard of her stranding and travelled to Tiree, she had been dead for 4 days, so much of the internal organ structure had been lost. Nonetheless we found convincing evidence that she had become chronically entangled and this was the most likely cause of her death. There were deep, granulating wounds around the tailstock and tell-tale twin linear abrasions on the underside of the tail fluke. These are consistent with a rope wrapping around the tail and trailing behind the animal, probably still attached to something at the other end. This would have made normal swimming very difficult, and we suspect the animal had been entangled for several days. She hadn’t fed recently but had swallowed a large amount of seawater, most likely as she eventually succumbed to the entanglement and drowned.
There were no ropes or gear left on the carcase; we’re assuming all this from the lesions we found on her body, so we don’t know if this was due to active fishing gear, abandoned or ‘ghost’ gear, or other marine debris. The lesions are very similar however to those we see from creel rope entanglement in baleen whales. This is the first killer whale we have seen which has been entangled, although we have had an increase in entanglement incidence in other large cetaceans over the past year.
These types of mortality are particularly tragic, however from examining this case we should be able to learn a little more about a poorly understood population. We have samples to examine age, reproductive status and pollutant burden, and this will form part of future studies.

Trump Makes Strange Claim About Water Efficient Toilets: 'People Are Flushing Toilets 10 Times, 15 Times'
President Donald Trump mocked water-efficiency standards in new constructions last week. Trump said, "People are flushing toilets 10 times, 15 times, as opposed to once. They end up using more water. So, EPA is looking at that very strongly, at my suggestion." Trump asked the Environmental Protection Agency (EPA) for a federal review of those standards since, he claimed with no evidence, that they are making bathrooms unusable and wasting water, as NBC News reported.

Former Monsanto Chairman and CEO Hugh Grant will have to testify in person at a St. Louis-area trial set for January in litigation brought by a cancer-stricken woman who claims her disease was caused by exposure to the company's Roundup herbicide and that Monsanto covered up the risks instead of warning consumers.
A powerful volcano on Monday rocked an uninhabited island frequented by tourists about 30 miles off New Zealand's coast. Authorities have confirmed that five people died. They expect that number to rise as some are missing and police officials issued a statement that flights around the islands revealed "no signs of life had been seen at any point,", as The Guardian reported.
"Based on the information we have, we do not believe there are any survivors on the island," the police said in their official statement. "Police is working urgently to confirm the exact number of those who have died, further to the five confirmed deceased already."
The eruption happened on New Zealand's Whakaari/White Island, an islet jutting out of the Bay of Plenty, off the country's North Island. The island is privately owned and is typically visited for day-trips by thousands of tourists every year, according to The New York Times.
My god, White Island volcano in New Zealand erupted today for first time since 2001. My family and I had gotten off it 20 minutes before, were waiting at our boat about to leave when we saw it. Boat ride home tending to people our boat rescued was indescribable. #whiteisland pic.twitter.com/QJwWi12Tvt— Michael Schade (@sch) December 9, 2019

At the time of the eruption on Monday, about 50 passengers from the Ovation of Seas were on the island, including more than 30 who were part of a Royal Caribbean cruise trip, according to CNN. Twenty-three people, including the five dead, were evacuated from the island.
The eruption occurred at 2:11 pm local time on Monday, as footage from a crater camera owned and operated by GeoNet, New Zealand's geological hazards agency, shows. The camera also shows dozens of people walking near the rim as white smoke billows just before the eruption, according to Reuters.
Police were unable to reach the island because searing white ash posed imminent danger to rescue workers, said John Tims, New Zealand's deputy police commissioner, as he stood next to Prime Minister Jacinda Ardern in a press conference, as The New York Times reported. Tims said rescue workers would assess the safety of approaching the island on Tuesday morning. "We know the urgency to go back to the island," he told reporters.
"The physical environment is unsafe for us to return to the island," Tims added, as CNN reported. "It's important that we consider the health and safety of rescuers, so we're taking advice from experts going forward."
Authorities have had no communication with anyone on the island. They are frantically working to identify how many people remain and who they are, according to CNN.
Geologists said the eruption is not unexpected and some questioned why the island is open to tourism.
"The volcano has been restless for a few weeks, resulting in the raising of the alert level, so that this eruption is not really a surprise," said Bill McGuire, emeritus professor of geophysical and climate hazards at University College London, as The Guardian reported.
"White Island has been a disaster waiting to happen for many years," said Raymond Cas, emeritus professor at Monash University's school of earth, atmosphere and environment, as The Guardian reported. "Having visited it twice, I have always felt that it was too dangerous to allow the daily tour groups that visit the uninhabited island volcano by boat and helicopter."
The prime minister arrived Monday night in Whakatane, the town closest to the eruption, where day boats visiting the island are docked. Whakatane has a large Maori population.
Ardern met with local council leaders on Monday. She is scheduled to meet with search and rescue teams and will speak to the media at 7 a.m. local time (1 p.m. EST), after drones survey the island, as CNN reported.
