There's Only One Carbon Negative Country in the World (Here's How They Do It)

In 2017, the small nation of Bhutan became the first and only carbon negative country in the world. That's right: not carbon neutral, carbon negative.

In an article on the subject, the Climate Council—an independent, Australia-based nonprofit organization dedicated to educating the public on matters related to climate change—defines carbon negative status as occurring when a country's carbon emissions are not only offset, but are actually in the negative due to the generation and exportation of renewable energy. There are several reasons for this impressive feat.

Bhutan—a small, landlocked country in the middle of the Himalayas—has a population of approximately 813,000 and produces 2.2 million metric tons of carbon dioxide per year. The country is 72 percent forest, and those forests trap more than three times their carbon dioxide output through a process called carbon sequestration, the long-term storage of carbon in plants, soil, and the ocean. This means that Bhutan is a carbon sink: It absorbs more carbon than it releases as carbon dioxide. Specifically, Bhutan is a carbon sink for more than 4 million tons of CO2 each year. In addition, the country exports most of the renewable electricity generated by its rivers, which is equivalent to 6 million tons of CO2.

Bhutan is also exceptionally environmentally friendly. This is partly because it takes a holistic view of development, measuring it with the Gross National Happiness Index instead of the Gross Domestic Product Index, like most countries. Instead of only prioritizing economic improvement, Gross National Happiness balances it with sociocultural and environmental improvement. The eco-conscious country invests in sustainable transport, subsidizes electric vehicles, and has an entirely paperless government.

Bhutan has pledged to remain carbon neutral for all time, and it's safe to say it's doing pretty well so far.

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.
