Scientists Warn of Threat of Plastic Waste on Marine Life

Scientists are warning that micro-plastics in the ocean and the toxic chemicals in them are posing a significant risk to giant animals like whales, sharks and manta rays that are marine filter feeders.

A new study published in the Trends in Ecology and Evolution journal said that such animals swallow thousands of cubic meters of seawater daily in an effort to capture plankton, in which case they can ingest micro-plastics directly from polluted water or indirectly through contaminated prey, the German News Agency (dpa) reported.

Micro-plastics are small plastic pieces less than five millimeters long, which are harmful to marine life.

The study added that plastic-associated chemicals and pollutants can accumulate over decades and alter biological processes in the animals, leading to altered growth, development and reproduction, including reduced fertility.

Elitza Germanov, lead researcher of the study, said: “While a definitive connection between micro-plastic ingestion and toxin exposure for filter feeders remains to be confirmed, studies into seabirds and small fish have found a link.”

The marine species are also in danger due to their habitat areas overlapping micro-plastic pollution hotspots like the Gulf of Mexico, the Mediterranean Sea, the Bay of Bengal and the Coral Triangle (an area from Malaysia to the Solomon Islands in the Pacific).

Many of the animals, like manta rays, are threatened species, so it is difficult to assess plastic concentrations via conventional methods, such as stomach analysis, Germanov said.

The study’s lead author explained: “So we are using the non-lethal sampling of small amounts of tissue, which we are testing for chemical tracers using sophisticated and sensitive analytical tools.”

Many of the filter-feeding animals live a long life, but have few offspring throughout their lives.

Maria Cristina Fossi, a co-author of the study, said another study she led on whale sharks in the Gulf of California and on fin whales in the Mediterranean Sea confirmed exposure to toxic chemicals.

“As these areas are hotspots for micro-plastics, our results could indicate that filter feeders are taking up micro-plastics in their feeding grounds,” she said.

Lately, there has been a large number of reports and studies on marine life facing an existential threat from the millions of tons of plastic waste that end up in the oceans each year.

A wave of low temperature sweeping southern China brought rare snowfall to ​Shanghai on Tuesday, delighting residents of the financial hub as authorities warned that the frigid weather could last for at least three days.

The city, on China's east coast, last ‌experienced a heavy snowfall ‌in January ‌2018. ⁠And ​just ‌last week, Shanghai basked in unusually high temperatures of 20 degrees Celsius (68 degrees Fahrenheit), which local media said had caused some osmanthus trees to bloom.

"The weather seems rather ⁠strange this year," said 30-year-old resident Yu Xin.

"In ‌general, the temperature ‍fluctuations have ‍been quite significant, so some people ‍might feel a bit uncomfortable," she said.

Chinese state media said other areas experienced sharp temperature drops, including Jiangxi and ​Guizhou provinces, which sit south of China's Yangtze and Huai ⁠rivers. Guizhou province is expected to experience temperature drops of 10 to 14 degrees Celsius, the Zhejiang News reported.

Across China, authorities have also shut 241 sections of major roads in 12 provinces including Shanxi, Inner Mongolia and Heilongjiang due to snowfall and icy ‌roads, state broadcaster CCTV said.

Warming temperatures are forcing Antarctic penguins to breed earlier and that's a big problem for two of the cute tuxedoed species that face extinction by the end of the century, a study said.

With temperatures in the breeding ground increasing 5.4 degrees Fahrenheit (3 degrees Celsius) from 2012 to 2022, three different penguin species are beginning their reproductive process about two weeks earlier than the decade before, according to a study in Tuesday's Journal of Animal Ecology. And that sets up potential food problems for young chicks.

“Penguins are changing the time at which they’re breeding at a record speed, faster than any other vertebrate,” said lead author Ignacio Juarez Martinez, a biologist at Oxford University in the United Kingdom. "And this is important because the time at which you breed needs to coincide with the time with most resources in the environment and this is mostly food for your chicks so they have enough to grow.''

For some perspective, scientists have studied changes in the life cycle of great tits, a European bird. They found a similar two-week change, but that took 75 years as opposed to just 10 years for these three penguin species, said study co-author Fiona Suttle, another Oxford biologist.

Researchers used remote control cameras to photograph penguins breeding in dozens of colonies from 2011 to 2021. They say it was the fastest shift in timing of life cycles for any backboned animals that they have seen. The three species are all brush-tailed, so named because their tails drag on the ice: the cartoon-eye Adelie, the black-striped chinstrap and the fast-swimming gentoo.

Suttle said climate change is creating winners and losers among these three penguin species and it happens at a time in the penguin life cycle where food and the competition for it are critical in survival.

The Adelie and chinstrap penguins are specialists, eating mainly krill. The gentoo have a more varied diet. They used to breed at different times, so there were no overlaps and no competition. But the gentoos' breeding has moved earlier faster than the other two species and now there's overlap. That's a problem because gentoos, which don't migrate as far as the other two species, are more aggressive in finding food and establishing nesting areas, Martinez and Suttle said.

Suttle said she has gone back in October and November to the same colony areas where she used to see Adelies in previous years only to find their nests replaced by gentoos. And the data backs up the changes her eyes saw, she said.

“Chinstraps are declining globally,” Martinez said. “Models show that they might get extinct before the end of the century at this rate. Adelies are doing very poorly in the Antarctic Peninsula and it’s very likely that they go extinct from the Antarctic Peninsula before the end of the century.”

Martinez theorized that the warming western Antarctic — the second-fasting heating place on Earth behind only the Arctic North Atlantic — means less sea ice. Less sea ice means more spores coming out earlier in the Antarctic spring and then “you have this incredible bloom of phytoplankton,” which is the basis of the food chain that eventually leads to penguins, he said. And it's happening earlier each year.

Not only do the chinstraps and Adelies have more competition for food from gentoos because of the warming and changes in plankton and krill, but the changes have brought more commercial fishing that comes earlier and that further shortens the supply for the penguins, Suttle said.

This shift in breeding timing “is an interesting signal of change and now it’s important to continuing observing these penguin populations to see if these changes have negative impacts on their populations,” said Michelle LaRue, a professor of Antarctic marine science at the University of Canterbury in New Zealand. She was not part of the Oxford study.

With millions of photos — taken every hour by 77 cameras for 10 years — scientists enlisted everyday people to help tag breeding activity using the Penguin Watch website.

“We’ve had over 9 million of our images annotated via Penguin Watch,” Suttle said. “A lot of that does come down to the fact that people just love penguins so much. They’re very cute. They’re on all the Christmas cards. People say, ‘Oh, they look like little waiters in tuxedos.’”

“The Adelies, I think their personality goes along with it as well,” Suttle said, saying there's “perhaps a kind of cheekiness about them — and this very cartoon-like eye that does look like it’s just been drawn on.”

More than 100 vehicles smashed into each other or slid off an interstate in Michigan on Monday as snow fueled by the Great Lakes blanketed the state.

The massive pileup prompted the Michigan State Police to close both directions of Interstate 196 Monday morning just southwest of Grand Rapids while officials worked to remove all the vehicles, including more than 30 semitrailer trucks. The State Police said there were numerous injuries, but no deaths had been reported.

Pedro Mata Jr. said he could barely see the cars in front of him as the snow blew across the road while driving 20-25 mph (32-40 kph) before the crash. He was able to stop his pickup safely, but then decided to pull his truck off the road into the median to avoid being hit from behind.

“It was a little scary just listening to everything, the bangs and booms behind you. I saw what was in front of me. I couldn’t see what was behind me exactly,” The Associated Press quoted Mata as saying.

The crash is just the latest impact of the major winter storm moving across the country. The National Weather Service issued warnings about either extremely cold temperatures or the potential for winter storms across several states starting in northern Minnesota and stretching south and east into Wisconsin, Indiana, Ohio, Pennsylvania and New York.

A day earlier, snow fell as far south as the Florida Panhandle and made it harder for football players to hang onto the ball during playoff games in Massachusetts and Chicago. Forecasters warned Monday that freezing temperatures are possible overnight into Tuesday across much of north-central Florida and southeast Georgia.

The Ottawa County Sheriff's office in Michigan said multiple crashes and jack-knifed semis were reported along with numerous cars that slid off the road. Stranded motorists were being bused to Hudsonville High School, where they could call for help or arrange a ride.

Officials expected the road to be closed for several hours during the cleanup.
One of the companies helping remove the stranded cars, Grand Valley Towing, sent more than a dozen of its trucks to the scene of the chain-reaction crash. Several towing companies responded in the brutally cold weather.

“We’re trying to get as many vehicles out of there as quickly as possible, so we can get the road opened back up,” manager Jeff Westveld said.
