Tree ‘Crop Circles’ Emerge in Japan, Results From 1973 Forestry Experiment
Photos of two "crop circles" of trees in Japan's Miyazaki prefecture have emerged online and on social media, causing netizens to marvel at the eerie forest formation.
Turns out, these cedar circles—which you can see on Google Earth—are the result of a forestry experiment conducted about 45 years ago.
The Japanese design and culture blog Spoon & Tamago explains:
According to documentation (PDF) we obtained from Japan's Ministry of Agriculture, Forestry and Fisheries, in 1973 an area of land near Nichinan City was designated as "experimental forestry" and one of the experiments was to try and measure the effect of tree spacing on growth. The experiment was carried out by planting trees in 10 degree radial increments forming 10 concentric circles of varying diameters.
Look closely at the photos and you'll notice that the height and size of the trees expands taller and bigger from the inner circle.
The height difference between the tallest tree and the shortest tree is about 5.3 meters, the document from Japan's Ministry of Agriculture, Forestry and Fisheries shows.
"Makes sense right? More space equals less competition for resources such as water and sunlight, so it's easier for these outer trees to grow bigger and stronger while those on the inside fight it out amongst themselves," writes Bored Panda.
This 3D Google Earth map shows that this experiment was even conducted on a slope.
Officials were planning to harvest the trees in about five years, but they are now thinking about preserving the circles given the new interest in them, according to Spoon & Tamago.
Britain's Prince William interviewed famed broadcaster David Attenborough on Tuesday at the World Economic Forum's annual meeting in Switzerland.
During the sit-down, the 92-year-old naturalist advised the world leaders and business elite gathered in Davos this week that we must respect and protect the natural world, adding that the future of its survival—as well as humanity's survival—is in our hands.
What's more, the accounting firm predicts that another 21 million electric cars will be on the road globally over the next decade due to growing market demand for clean transportation, government subsidies, as well as bans on fossil fuel cars.

Plastic pollution in the world's oceans has become a global environmental crisis. Many people have seen images that seem to capture it, such as beaches carpeted with plastic trash or a seahorse gripping a cotton swab with its tail.
Greenland is melting about four times faster than it was in 2003, a new study published Monday in the Proceedings of the National Academy of Sciences found, a discovery with frightening implications for the pace and extent of future sea level rise.
"We're going to see faster and faster sea level rise for the foreseeable future," study lead author and Ohio State University geodynamics professor Dr. Michael Bevis said in a press release. "Once you hit that tipping point, the only question is: How severe does it get?"
Finally, some good news about the otherwise terrible partial government shutdown. A federal judge ruled that the Trump administration cannot issue permits to conduct seismic testing during the government impasse.
The Justice Department sought to delay—or stay—a motion filed by a range of coastal cities, businesses and conservation organizations that are suing the Trump administration over offshore oil drilling, Reuters reported. The department argued that it did not have the resources it needed to work on the case due to the shutdown.
Most people have heard of the Amazon, South America's famed rainforest and hub of biological diversity. Less well known, though no less critical, is the Pantanal, the world's largest tropical wetland.
Like the Amazon, the Pantanal is ecologically important and imperiled. Located primarily in Brazil, it also stretches into neighboring Bolivia and Paraguay. Covering an area larger than England at more than 70,000 square miles, the massive wetland provides irreplaceable ecosystem services that include the regulation of floodwaters, nutrient renewal, river flow for navigability, groundwater recharge and carbon sequestration. The wetland also supports the economies of the four South American states it covers.

Organizers said 35,000 people marched through the streets of the German capital on Saturday to say they're "fed up" with industrial agriculture and call for a transformation to a system that instead supports the welfare of the environment, animals and rural farmers.

If you have ever considered making the switch to an environmentally friendly electric vehicle, don't drag your feet. Though EV prices are falling, and states are unveiling more and more public charging stations and plug-in-ready parking spots, the federal government is doing everything it can to slam the brakes on our progress away from gas-burning internal combustion engines. President Trump, likely pressured by his allies in the fossil fuel industry, has threatened to end the federal tax credits that have already helped put hundreds of thousands of EVs on the road—a move bound to harm not only our environment but our economy, too. After all, the manufacturing and sale of EVs, hybrids, and plug-in hybrids supported 197,000 jobs in 2017, according to the most recent U.S. Energy and Employment Report.
