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.

The Navajo Nation have decided to stop pursuing the acquisition of a beleaguered coal-fired power plant in Arizona, locking in the plant to be taken offline and its associated coal mine to close later this year.
A Navajo Nation Council committee voted 11-9 last week to stop pursuing the purchase of the 2,250-megawatt Navajo Generating Station, which with the Kayenta coal mine provides more than 800 jobs to primarily Navajo and Hopi workers as well as tribal royalties.
A coalition of utilities that own the plant said in 2017 it would cease operations due to increased economic pressure, and the plant's future has proved a flash point for national and regional energy policy and raised larger questions on how Native communities will handle ties to fossil fuel industries as the economy changes.

Other countries don't seem to have a problem getting their high-speed rail systems on track. This superfast, fuel-efficient form of mass transit is wildly popular throughout Asia and the European Union. Japan's sleek Shinkansen line, the busiest high-speed rail system in the world, carries an estimated 420,000 riders every weekday. In China, the new Fuxing Hao bullet train now hurries more than 100 million passengers a year between Beijing and Shanghai at a top speed of 218 miles an hour, allowing its riders to make the trip of 775 miles — roughly the distance from New York City to Chicago — in about four and a half hours. Spain, Germany and France together have more than 4,500 miles of track dedicated to high-speed rail, over which more than 150 million passengers travel annually.

Growing up in a plastic-free home, I was sheltered from the plastic waste crisis. I (Coda) went to a very progressive school that had vegan lunch items, farm animals and ran on solar power. My mom produces zero-waste events and my dad is a sailor, so we're very passionate about the ocean. When I was nine years old, we moved back to Manhattan Beach, California and I started 3rd grade in a public school. This was the first time I really understood that plastic-free living is not the norm; single-use plastics were everywhere, especially in the cafeteria. Once I recognized this problem, I knew I had to make a difference.
