Good News: Being Lazy Can Be Good for the Environment

You may feel bad about the days when you never leave the couch, but there is an upside to working remotely, watching Netflix, ordering food and consumer goods online, and lying around your house scrolling through Facebook. A new study in the journal Joule, spotted by Fast Company, finds that as technology allows people to spend more time at home, it's reducing American energy usage.

Researchers from the University of Texas at Austin examined data from the Bureau of Labor Statistics' annual American Time Use Survey, finding that between 2003 and 2012, people spent more time at home and less time traveling to and from stores and work. According to this data, Americans in 2012 spent a total of 7.8 more days at home than in 2003 and 1.2 fewer days traveling. That means they weren't getting in their cars and burning up fossil fuels to drive around town. And, if fewer people are working in offices overall, presumably those buildings require less energy to run (for example, they don't need as much power for lights or air conditioning). In total, the researchers estimate that Americans used 1.8 percent less energy as a nation because of this home-bound change in lifestyle.

Considering that these metrics are from 2012, it's likely that people are spending even less time traveling outside their houses these days. U.S. government data show that e-commerce has been a steadily growing portion of total retail sales for a decade.

There's reason to resist becoming a total hermit, though—and it's not just the need for Vitamin D or exercise. There are aspects of staying home that aren't quite so carbon-friendly—ones that aren't fully addressed in this study. You may be staying off the road, but the trucks delivering your groceries and goods aren't, and they require fossil fuel. Cities are currently overwhelmed with delivery trucks ferrying packages from Amazon, Peapod, Postmates, and all the other online services that people can now use as their go-to shopping destinations. The massive upsurge in people getting groceries, office supplies, home goods, clothing, and just about anything else delivered to their homes has led to an increase in freight traffic, because trucks still have to be deployed to get those packages to front doors. (At least until drone delivery takes off.)

Staying at home and watching a movie on Netflix instead of going out to the movies saves energy, but having your toilet paper sent to your home still requires some gas. Time will tell whether shipping services dropping off purchases, versus people going out shopping, significantly reduces carbon usage. One study found that results depend on whether the shopper lives in a suburban or urban environment, among other issues [PDF]. So enjoy your Netflix night, but don't get too smug about your Amazon purchases just yet.

2624-Year-Old Cypress Tree Discovered in North Carolina Swamp

National Love a Tree Day on May 16 is a day to appreciate all the world's trees, but a bald cypress recently identified in North Carolina is especially deserving of recognition. As Live Science reports, scientists date the tree to 2624 years old, making it one the oldest living non-clonal trees on Earth.

For their study, recently published in the journal Environmental Research Communications, a team of researchers studied the rings of trees in North Carolina's Black River swampland to learn more about climate history in the eastern United States. Bald cypresses are known to have impressive lifespans, but after analyzing specimens in the Black River's Three Sisters Swamp, an area that's notable for its long-lived trees, the scientists discovered that cypresses can grow to be even older than previously believed. The 2624-year-old cypress tree they found predates the Great Wall of China and the Roman Empire. Other remarkably old trees, including a 2088-year-old cypress, were also identified in the same grove.

The North Carolina cypresses are old, but there are other types of trees that can grow to be much older. Clonal tress are genetically identical plants that reproduce asexually from a single ancestor. Old Tjikko, a clonal tree in Sweden, has a root system that dates back 9550 years.

Despite all that North Carolina's bald cypress trees have endured, their lives are under threat. The swamp where the 2624-year-old tree stands is located just 6.5 feet above sea level, which means that floods driven by climate change could damage its habitat. And though the grove is in a protected area, industrial runoff and logging that's happening nearby could impact the trees' health. North Carolina is considering establishing a Black River State Park where the trees grow to further protect the ancient natural wonders.

This Beverage Maker Lets You Enjoy Carbonated Drinks Without Hurting the Environment

Whether you're preparing breakfast before you head off to work or looking for something to wash down lunch, procuring the perfect beverage is vital. If it's a carbonated drink, though, with that comes the carbon dioxide emissions that arise every time you hear that classic "fssst" sound from cracking one open. These emissions are actually quite harmful to the environment.

But thanks to the newly unveiled Spärkel, curating carbonated drinks can be done without using CO2 or any artificial ingredients.

"If you walk into any grocery store, the explosion in the popularity of sparkling drinks is plain to see with more choices and flavors than ever before, but why buy off-the-shelf when it is healthier, cheaper, and more fun to create your own drinks at home?" Darren Hatherell, CEO of Spärkel, said in a press release. "With Spärkel, we created a system that lets people use the freshest ingredients and convenient carbonation process to experiment and unleash their creativity in a way that is kind to their wallet and the environment."

Users can place any kind of ingredients they wish—berries, citrus, cucumbers, etc.—along with their drink of choice—water, tea, cocktails—into the 25 oz. (750 mL) bottle and choose what level, from one to five, of fizz they'd like to have added to their drink. The sealed chamber generates CO2 naturally from a sachet of Spärkel Carbonator powder, which is "made of a special granulation of citric acid and sodium bicarbonate." The CO2 bubbles are cycled through the liquid, and within a couple of minutes, you have a completely personalized sparkling drink.

On top of all that, the beverage maker is suitable for any number of usages from water and juices to cocktails. It also comes in nine different colors—black, white, gray, yellow, orange, red, blue, green, and pink—so it can match up with whatever kitchen palette you have.

To get your hands on the Spärkel, check it out on Indiegogo, where it's available for a pre-sale price of $59.
