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.

How to Build an Igloo, According to a Canadian Film From 1949

Centuries before you started building snow forts in your backyard, the Inuit had mastered using snow as construction material. This 1949 video, produced by the National Film Board of Canada (and with narration that uses some outdated terminology), illustrates how exactly people native to the Arctic can erect warm, temporary homes using nothing but a knife and the snow beneath their feet. The artifact was spotted by The Kid Should See This.

The igloo (or iglu in Inuktitut) in this footage takes around 90 minutes to erect, but a similar structure can be built by a skilled person in as little as 40 minutes. To put together the shelter, the two men carve up firm, packed snow into blocks that are about 2 feet tall, 3 feet wide, and 4 inches thick.

After the first row of blocks is placed in a circle on the ground, the builder slices a section of the blocks to create a slope. Each row that's placed on this foundation will spiral upward, creating a shape in which the blocks support their own weight. By the time the keystone block is fitted into the top, the igloo is strong enough to support the weight of a man.

The final steps are carving a doorway out of the bottom of the structure and plugging up the cracks with additional snow from outside. Even on a frigid Arctic night, the temperature of a well-insulated igloo can reach 40 degrees above the temperature outside. And the warmer the igloo gets over time, the stronger it becomes: The heat from the Sun and the bodies of the inhabitants melt the outer layers of the blocks, and that water eventually freezes to ice, giving the home more insulation and structural integrity.

If you aren't ready to build an igloo, here are some less intimidating snow projects to tackle this winter.

Charge Your Gadgets Anywhere With This Pocket-Sized Folding Solar Panel

Portable power banks are great for charging your phone when you’re out and about all day, but even they need to be charged via an electrical outlet. There's only so much a power bank can do when you’re out hiking the Appalachian Trail or roughing it in the woods during a camping trip.

Enter the SolarCru—a lightweight, foldable solar panel now available on Kickstarter. It charges your phone and other electronic devices just by soaking up the sunshine. Strap it to your backpack or drape it over your tent to let the solar panel’s external battery charge during the day. Then, right before you go to bed, you can plug your electronic device into the panel's USB port to let it charge overnight.

It's capable of charging a tablet, GPS, speaker, headphones, camera, or other small wattage devices. “A built-in intelligent chip identifies each device plugged in and automatically adjusts the energy output to provide the right amount of power,” according to the SolarCru Kickstarter page.

A single panel is good “for small charging tasks,” according to the product page, but you can connect up to three panels together to nearly triple the electrical output. It takes roughly three hours and 45 minutes to charge a phone using a single panel, for instance, or about one hour if you’re using three panels at once. The amount of daylight time it takes to harvest enough energy for charging will depend on weather conditions, but it will still work on cloudy days, albeit more slowly.

The foldable panel weighs less than a pound and rolls up into a compact case that it can easily be tucked away in your backpack or jacket pocket. It’s also made from a scratch- and water-resistant material, so if you get rained out while camping, it won't destroy your only source of power.

You can pre-order a single SolarCru panel on Kickstarter for $34 (less than some power banks), or a pack of five for $145. Orders are scheduled to be delivered in March.
