Sorry, Suckers: Seattle Becomes First U.S. City to Ban Plastic Straws and Utensils

The plastic straw industry continues to be under siege. In early 2018, Queen Elizabeth II banned the soda-slurping devices from Buckingham Palace. McDonald’s followed suit by scrubbing their 1300 UK restaurants free of the environmentally unfriendly tubes, which prove hard to recycle (they’re often too small to make it through recycling sorters) and can take a long time to decompose.

Seattle has now become the latest to toss them aside, The Hill reports. July 1 marked the beginning of a ban on plastic straws as well as plastic utensils—the first such citywide prohibition in the United States. The ban applies to more than 5000 restaurants and eateries in the city, and is part of an overall effort to curb landfill and water-clogging waste. Businesses caught doling out the contraband could be fined up to $250.

Consumers will be able to request compostable plastic or paper straws, though neither one is a perfect solution: The former can still prove problematic in oceans, and the latter can shrivel up when submerged in liquid. Those with medical needs will still have access to flexible straws.

New York and San Francisco are considering similar bans. Some companies are already anticipating a world with limited access to straws. Starbucks recently introduced a specially-designed lid for their cold drinks that makes sipping easier.

Being Surrounded By Greenery Can Be Good for Your Heart

Living in a place with a little greenery is good for your health in more ways than one. Recent research has found that people perceive their health status as significantly better if they live around trees, and for good reason—in addition to helping you chill out, exposure to lots of green vegetation may be good for your cardiovascular health, as Cardiovascular Business reports.

A new study in the Journal of the American Heart Association suggests that living in green areas is correlated with certain biomarkers for cardiovascular health. Scientists analyzed blood and urine samples from 408 people at a cardiology clinic, then compared the results to satellite-derived data on the levels of greenery around those patients’ homes (using 820-foot and half-mile radiuses).

Adjusting for age, sex, race, smoking status, “neighborhood deprivation” and other factors known to be linked heart disease rates, the researchers found that living in a green area was correlated with several markers of a healthy heart. Blood and urine samples from those participants who lived in green neighborhoods showed lower levels of sympathetic activation—the body’s automatic fight-or-flight response, which raises the heart rate and is involved in heart failure. Those participants also had reduced oxidative stress—an imbalance between free radicals and antioxidants in the body, which can cause tissue damage and is linked to chronic disease. And they had higher angiogenic capacity, which refers to the body’s ability to form new blood vessels.

All this suggests that being around trees is somehow linked to having a healthier heart, though these are just biomarkers, not rates of heart disease or major cardiac events. But while scientists have yet to prove directly that being around trees causes your heart to be healthier, it’s not the first study to suggest a link. In 2015, a study of American women found that rates of heart disease went up in certain areas after a beetle invasion killed off a significant number of trees. Other studies have suggested that being around trees can reduce stress, which in itself may affect your risk of heart disease. Luckily, whether it qualifies as heart medicine or not, spending more time hanging out under trees couldn’t hurt.

Survey Finds Microplastics in the Guts of All Seven Sea Turtle Species

Plastic is all around us—in our landfills, in our oceans, and even in the bellies of some of Earth's most vulnerable creatures. For a new paper in the journal Global Change Biology, researchers checked the guts of 102 deceased sea turtles, some of which belong to critically endangered species, and found that all of them tested positive for microplastics.

For the study, UK-based researchers from the University of Exeter, Plymouth Marine Laboratory, and Greenpeace Research Laboratories studied turtles that had died after being stranded or accidentally caught by commercial fishing operations. All seven marine turtle species were tested, including the endangered green turtle and the critically endangered hawksbill and Kemp's ridley turtles.

The specimens were found off the coasts of North Carolina in the Atlantic Ocean, northern Cyprus in the Mediterranean Sea, and Queensland, Australia in the Pacific Ocean. Necropsies revealed plastic particles under 5mm in length, while microplastic fibers were one of the most common contaminants detected in their guts. These can come from a variety of sources, including clothing, tires, cigarette filters, ropes, and fishing nets. More than 800 synthetic particles were found in the turtles. Only one section of the gut was tested in each animal, so the actual number is likely 20 times higher, according to a University of Exeter statement.

A 2015 study, also in Global Change Biology, estimated that 52 percent of all sea turtles may have ingested microplastics.

"From our work over the years, we have found microplastic in nearly all the species of marine animals we have looked at, from tiny zooplankton at the base of the marine food web to fish larvae, dolphins, and now turtles," Dr. Penelope Lindeque, of the Plymouth Marine Laboratory, said in the statement. "This study provides more evidence that we all need to help reduce the amount of plastic waste released to our seas and maintain clean, healthy, and productive oceans for future generations."

The consequences of ingesting microplastics—via contaminated water or by eating other fish or plants—isn't currently known. The particles are small enough to pass through the gut without causing any blockages, unlike larger plastics which can—and do—wreak havoc on marine life. While the authors concluded that microplastics, at their current levels, post less of a threat than fisheries bycatch and entanglements in fishing gear, they said further studies should be conducted to determine the actual risks.

"They may possibly carry contaminants, bacteria, or viruses, or they may affect the turtle at a cellular or subcellular level," lead author Dr. Emily Duncan of the University of Exeter said. "This requires further investigation."
