Cigarette Butts Are the Number One Source of Ocean Trash

The health consequences of smoking have been well-documented, but cigarettes can continue to do harm long after they've been stubbed out. As Business Insider reports, cigarette butts account for the largest source of trash in the world's oceans, outnumbering plastic items like straws and water bottles.

Even with cigarette sales sharply declining in recent years, the amount of litter they produce remains significant. It's difficult to recycle filters and often dangerous to throw them in the trash with flammable materials. With public ashtrays scarcer than they once were, many smokers opt to leave the remains on the ground.

Most filters contain cellulose acetate, a non-biodegradable type of plastic. So instead of breaking down over time, the waste washes into streams, rivers, and, when they're disposed of on beaches, directly into the sea.

The Ocean Conservancy estimates that roughly 60 million cigarette butts have been collected from the ocean since the 1980s. Unlike other waste items that pollute the ocean but often get more attention, including plastic bags and six-pack rings, cigarette filters can inflict serious damage on marine life. They contain many of the same chemicals as full cigarettes, including nicotine, lead, and arsenic.

Some unusual initiatives to clean up cigarette butts have been proposed over the years, including training crows to collect them and using them to pave roads, but real change needs to start with cigarette smokers. Instead of leaving them on the sidewalk, filters should be extinguished and safely stored until there are enough of them to send to a special recycling center that handles difficult-to-recycle materials. TerraCycle will even send you a special recycling receptacle designed for collecting cigarette ashes and filters.

There Could Be Hundreds of Frozen Corpses Buried Beneath Antarctica's Snow and Ice

Scientists and explorers take a number of risks when they travel to Antarctica. One of the more macabre gambles is that they'll perish during their mission, and their bodies will never be recovered. According to the BBC, hundreds of frozen corpses may be trapped beneath layers and layers of Antarctic snow and ice.

“Some are discovered decades or more than a century later,” Martha Henriques writes for the BBC series Frozen Continent. “But many that were lost will never be found, buried so deep in ice sheets or crevasses that they will never emerge—or they are headed out towards the sea within creeping glaciers and calving ice.”

In the world’s most extreme regions, this is not uncommon. For comparison, some estimates suggest that more than 200 bodies remain on Mt. Everest. Antarctica's icy terrain is rugged and dangerous. Massive crevasses—some concealed by snow—measure hundreds of feet deep and pose a particularly serious threat for anyone crossing them on foot or by dogsled. There’s also the extreme weather: Antarctica is the coldest, driest, and windiest place on Earth, yet scientists recently discovered hundreds of mummified penguins that they believe died centuries ago from unusually heavy snow and rain.

One of the most famous cases of a left-behind body on Antarctica dates back to the British Antarctic Expedition (also known as the Terra Nova Expedition) of 1910 to 1913. British explorer Robert Falcon Scott and his four-man team hoped to be the first ones to reach the South Pole in 1912, but were bitterly disappointed when they arrived and learned that the Norwegian explorer Roald Amundsen had beaten them to it.

On the return trip, Scott and his companions died of exposure and starvation while trapped by a blizzard in their tent, just 11 miles from a food depot. Two of those bodies were never found, but the others (including Scott’s) were located a few months after their deaths. Members of the search party covered their bodies in the tent with snow and left them there. The bodies have since travelled miles from their original location, as the ice grows and shifts around them.

Other evidence suggests people landed on Antarctica decades before Scott’s team did. A 175-year-old human skull and femur found on Antarctica’s Livingston Island were identified as the remains of a young indigenous Chilean woman. No one yet knows how she got there.

Accidents still happen: After coming close to completing the first solo, unaided traverse of Antarctica, British adventurer Henry Worsley died of organ failure following an airlift from the continent in 2016. Most modern-day polar visitors, however, have learned from past missteps.

How Waffle House Helps Measure the Severity of a Natural Disaster

There are a lot of ways the Federal Emergency Management Agency (FEMA) assesses and addresses the severity of a natural disaster. Meteorology can predict movement patterns, wind gusts, and precipitation. Resources are dispatched to areas hit hardest by torrential weather.

But when the agency needs an accurate, ground-level gauge for how a community is coping during a crisis, they turn to Waffle House.

Since 2004, FEMA has utilized what former administrator Craig Fugate called the “Waffle House Index.” Because the casual dining chain is open 24 hours a day, seven days a week, tracking to see if a location is closed or working with limited supplies can help inform the agency as to whether affected areas are ailing or taking steps toward normalcy.

“If a Waffle House is closed because there's a disaster, it's bad,” Fugate told NPR in 2011. “We call it red. If they're open but have a limited menu, that's yellow ... If they're green, we're good, keep going. You haven't found the bad stuff yet.”

For FEMA, the ability to order a plate of smothered and covered hash browns is an important analytic. If a Waffle House is having trouble getting stock, then transportation has been interrupted. If the menu is limited, then it’s possible they have some utilities but not others. If its locations have locked their doors, inclement weather has taken over. The chain’s locations would normally stay open even in severe conditions to help first responders.

The company has opened a Waffle House Storm Center to gather data in anticipation of Hurricane Florence, a Category 2 storm expected to touch down in the Carolinas this week. But not all locations are taking a wait-and-see approach. One Waffle House in Myrtle Beach, South Carolina has already closed due to the looming threat, making it the first red dot on the Index.
