City dwellers are going hyper-local to experience nature
Most shelter-at-home orders allowed for people to visit national parks or nature preserves, but when too many people starting visiting these places, governments started restricting access to them as well. And although it’s frustrating to be separated from the great outdoors, staying home has Read More...
Improving soil carbon storage is a win for the planet and our food systems
Feeding a growing population on a planet with finite resources will require getting more creative and sustainable with how we operate our food systems. A new study has found that one key to protecting the future of our planet and people is carbon storage in soil. Plants pull carbon out of our Read More...
Critically endangered turtles hatch undisturbed on people-free beaches
At the start of each April, people on the northeastern shorelines of Brazil can witness the critically-endangered hawksbill sea turtles emerge from their eggs and make their first steps into the waters of the Atlantic. But as people have been advised to stay indoors to slow the spread of the Read More...
This tannery turns discarded billy goat hides into biodegradable leather
While the Optimist Daily is staunchly against killing animals for the sole purpose of harvesting fur or making leather, we do believe that if an animal is killed in the livestock industry, then all of its parts should be put to use instead of wasted. In the UK, commercial goat-milking is growing Read More...
Urban planners now know which tree is best for sound absorption in the city
Cities are notoriously noisy places, which is why urban planners are increasingly turning to trees as a buffer for noise. To identify which trees do the best job at muffling noise, researchers from University College London (UCL) recently evaluated 13 species of tree such as beech or willow trees Read More...
Nigerian citizen designs portable hand-washing stations for his city
Hand-washing is one of the most promoted and effective ways to prevent the spread of COVID-19, but what about regions where hand-washing facilities are not readily accessible? An estimated 157 million Nigerians lack adequate hand-washing facilities, which prompted one resident, Bamigbose Adams, to Read More...
Researcher says COVID-19 will reduce European emissions by 24 percent
Yesterday we shared a story about how the COVID-19 outbreak demonstrates society’s ability to act fast in the face of a crisis. If we choose to apply this amazing human capacity for action to the climate crisis, we may already have a bit of a head start with massive emissions drops due to the Read More...
Study suggests quick action could successfully restore oceans by 2050
A global team of researchers recently published an article in the scientific journal Nature detailing the state of our ocean's health, and unlike most projections of the ocean’s future health, this paper cautiously explains that we can successfully restore the ocean by 2050—if we act fast. Read More...
Methane-loving microbes may help reduce emissions from melting permafrost
As the climate warms up, polar ice and glaciers aren’t the only things at risk melting. Permafrost — the frozen layer of soil that underlies the Arctic tundra — is beginning to thaw as well, with scientists concerned that this will release huge amounts of greenhouse gases stored there. But Read More...
The Mexican gray wolf population in the US rose sharply in 2019
Exciting news from the US Fish and Wildlife Service. In a recent census, researchers discovered that the US population of endangered Mexican gray wolves jumped by 24 percent last year. That’s especially exciting for conservationists who haven’t seen a leap in numbers that high since 2014. The Read More...
