A Free Cup Share Program Is Coming to Coffee Shops in Boulder, Colorado

Paper coffee cups are wasteful, taking decades to break down in a landfill after they're used for just a small part of someone's morning. But they're also irresistibly convenient to many. A new startup called Vessel Works is aiming to tackle the waste problem at coffee shops by applying the convenience of disposable to-go cups to reusable mugs, Fast Company reports.

The program, which is launching in four Boulder, Colorado cafes, takes the pressure off of customers to provide their own reusable cups. Instead, they can download an app and use it to check out an insulated, stainless steel mug free of charge. Throughout the day, the app updates them on ways their choice has made a difference, including how much waste they've prevented, how much water they've conserved, and how much they've reduced their carbon footprint. When they're done with the drink, users have five days to return their mug to a Vessel kiosk; from there it will be cleaned in one of the startup's facilities and returned to a cafe where the cycle will start all over again.

Vessel isn't the first company to attempt to bring reusable cups into the sharing economy. In 2016, coffee shops in Hamburg, Germany adopted a program where customers could acquire a mug for a small deposit and return it to a participating cafe to get their money back. Vessel Works's program differs in that users are never asked to pay unless they fail to return their cups on time (in that case, they'll be charged a fee).

Vessel is currently working with Boxcar Coffee Roasters and Trident Booksellers and Cafe in Boulder, and is coming soon to Seeds Library Cafe at the Boulder Public Library and the Pekoe Sip House at the University of Colorado. The startup hopes to eventually expand to more cafes and install dropoff kiosks at more convenient locations like transit stops.

More Than Half of Wild Coffee Species Could Go Extinct

Your morning cup of coffee is under threat. A study published today in Science Advances asserts that a majority of the world’s wild coffee species are at risk of extinction. The main two types we rely on for our caffeine fix—arabica and robusta beans—are both threatened by climate change and deforestation.

The team of UK-based researchers used Red List of Threatened Species criteria from the International Union for the Conservation of Nature to classify the risks facing the world’s 124 known species of wild coffee. About 60 percent of them—or 75 different species—face possible extinction in the coming decades. This represents “one of the highest levels recorded for a plant group,” researchers write in their paper.

Partly to blame are the severe droughts associated with climate change, as well as deforestation. Other threats include the spread of fungal pathogens and coffee wilt disease in Central and South America and Africa, respectively, as well as social and economic factors for growers.

“Considering threats from human encroachment and deforestation, some [coffee species] could be extinct in 10 to 20 years, particularly with the added influence of climate change," lead author Aaron P. Davis, of the Royal Botanic Gardens, Kew, tells CNN.

Davis’s previous research stressed that arabica, which is already listed as an endangered species, could be extinct within 60 years. Most of the coffee plants we rely on are farmed, but wild coffee is no less important. Some wild species are resistant to disease and have other useful genes that could be introduced to commercial crops. That way, the cultivated varieties might endure the effects of climate change better and stick around a little longer.

Consumers aren’t the only ones concerned, either. Coffee farming is an industry that supports about 100 million workers around the world. One way of conserving the plants is to store their seeds and genes, but Hanna Neuschwander, the director of communications for the industry group World Coffee Research, tells Mashable that these seed banks aren’t well established yet. For now, the focus is on preserving the plants themselves.

Elephants Are Evolving Without Tusks Thanks to Poaching

Natural selection can take millions of years to shape a gene pool, but in parts of Africa, the extreme pressures of poaching may have changed elephants in just a few decades. As National Geographic reports, more tuskless elephants have emerged in regions where their ivory has made them a target.

Elephant poaching has long been in a problem Africa, but the crisis reached a fever pitch during Mozambique's 15-year civil war. Between 1977 and 1992, 90 percent of the elephants living in the country's Gorongosa National Park were slaughtered for ivory used to fund the conflict.

The diminished numbers aren't the only thing that looks different about Gorongosa's elephants today. Poachers often kill male elephants first because they have bigger tusks, and once they're eliminated, the hunters will go after females. Typically, about 2 to 4 percent of all female African elephants never develop tusks—but among female elephants that survived Mozambique's civil war, that number is 51 percent. The effects of poaching can also be observed in the next generation. Roughly 32 percent of female elephants born after 1992 are tuskless.

The trend can be seen in other parts of Africa where poaching has ravaged elephant populations. In Ruaha National Park in Tanzania, elephant behavior researcher Josephine Smit has observed that over one fifth of female elephants older than 5 years lack tusks. Tusklessness rates reach about 35 percent in females over 25.

The statistics are even harder to ignore in South Africa's Addo Elephant National Park, where tuskless animals made up 98 percent of all female elephants in the early 2000s. South Luangwa National Park in Zambia, Lupande Game Management Area in Zambia, and Queen Elizabeth National Park in Uganda each reported higher-than-average rates of tusklessness immediately following the ivory wars of the 1970s and '80s.

Though poaching is on the decline thanks to bans on the ivory trade and other conservation efforts in Africa, its impact can still be felt. In East Africa, the elephant population was nearly halved between 2008 and 2018. The establishment of wildlife preserves, DNA tracing, and GPS tracking are just a few of the ways conservationists are working to crack down on poachers and restore the species.
