As convenient as monthly and daily-use contact lenses can be for those who aren't blessed with 20/20 vision, they can also be harmful to the environment and contribute to microplastic pollution when they’re flushed down the drain.

The good news is that the blister packs your contact lenses come in can be recycled in a way that requires very little time and effort. If you're a contact lens wearer and want to do your part to reduce plastic waste, there’s a simple solution: Just place the empty blister packs inside a plastic bottle and drop it into the plastic recycling bin once it’s full. (Just make sure you're discarding the foil covering the blister pack first.)

Of course, it’s always better to use as few plastic bottles as possible, so only do this if you were already using those bottles anyway. If your household is fairly anti-plastic, there’s another option. Contact lens manufacturer Bausch + Lomb offers its own recycling program, called One by One. The company collaborated with TerraCycle to reduce waste by recycling all parts of the product, including the used blister pack, top foil, and contact lenses themselves. The company accepts all brands of contact lens products and estimates that it has recycled more than 25,000 pounds of packaging to date.

“Once received, the contact lenses and blister packs are separated and cleaned,” Bausch + Lomb explains on its website. “The metal layers of the blister packs are recycled separately, while the contact lenses and plastic blister pack components are melted into plastic that can be remolded to make recycled products.”

The reason why so many plastic blister packs end up in landfills is because the pieces are too small to be sorted properly at recycling plants. It’s the same problem that affects plastic bottle caps, which is why it’s recommended to leave the caps on, as long as your recycling program allows it.

Optometry offices across the country are participating in Bausch + Lomb's recycling program, and you can visit the company’s website to find out if there are any drop-off points near you. If it's more convenient, you can also place the items in a cardboard box and mail them in, using a free shipping label that’s available online.

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.
