This Man Searched for the Yeti for 60 Years—and Found It

A local hunter I worked with said he thought what I’d found was a tree bear. I’d never heard of a tree bear in this region. Suddenly we had an explanation for where the thumb came from. A bear that lives in a tree forces an inner digit down so it can make an opposable grip. Normal bears cannot make an opposable grip. But if you’re spending a lot of time in the tree, you train that one thumb to grab a branch or break bamboo. So I spent two years trying to figure out whether it was a species, sub-species, or a juvenile bear.

The Downside of Solar Energy


Hurricane Irma Aftermath On St. Thomas

The solar economy continues its dramatic growth, with over a half-terawatt already installed around the world generating clean electricity. But what happens to photovoltaic (PV) modules at the end of their useful life? With lifespans measured in decades, PV-waste disposal may seem to be an issue for the distant future. Yet, the industry ships millions of tons every year, and that number will continue to rise as the industry grows. Total e-waste—including computers, televisions, and mobile phones—is around 45 million metric tons annually.

HOW MUCH CAN DIETARY CHANGES AND FOOD PRODUCTION PRACTICES HELP MITIGATE CLIMATE CHANGE?


balanced-diet-feature

“Balanced diets featuring plant-based foods, such as coarse grains, legumes, fruits and vegetables, and animal-sourced food produced sustainably in low greenhouse gas emission systems, present major opportunities for adaptation to and limiting climate change,” Debra Roberts, co-chair of IPCC Working Group II, said in a press release. (In the summary of the report, the IPCC acknowledges that factors like financial barriers and cultural habits may influence the adoption of such diets.)

Greta Thunberg: The Crusader Kid


greta-thunberg-4

The young shall change the world. Amen.

WHEN IT COMES to Greta Thunberg, people fall into one of three camps: they either love her, hate her or don’t know about her. Those who appreciate her are leaders like António Guterres (Secretary-General of the UN), US Congresswoman Alexandria Ocasio-Cortez and Barack Obama. Those who dismiss her are the likes of Canadian businessman and politician Maxime Bernier, Harvard historian Niall Ferguson and climate sceptic Bjørn Lomborg. But this much is clear, she is arguably the world’s best-known 16-year-old today.

China Experiments with a New Kind of Megalopolis


pearl-river-delta-china

Trust China to do the most bold things.

Chen Yalei, the financial broker, says Beijing is making a kind of offer to the cities in the Greater Bay Area that they simply can’t refuse. “Of course, there will be major shifts and, of course, some of these cities will lose importance while others gain ground.” But, he adds, at least for the time being, Hong Kong will remain indispensable, as the financial center of the Pearl River Delta and as China’s gateway to the world.

And afterwards? “The reformer Deng Xiaoping created a monument to himself in Shenzhen, and for his successor, Jiang Zemin, it was in Shanghai ” says Chen Yalei. “The Greater Bay Area is the project that President Xi Jinping intends to be remembered by in the history books.”

The underwater Indian village that emerges once a year


maxresdefault

The village of Curdi was nestled between two hills in the Western Ghats with the Salaulim river – a tributary of one of the major rivers in Goa – running through it.

It was once a thriving village in south-eastern Goa.

In 1986, the village as its residents knew it ceased to exist. The state’s first dam was constructed and, as a consequence, the village was completely submerged.

But every year in May, the water recedes to reveal what is left of it.

‘We’re not a dump’ – poor Alabama towns struggle under the stench of toxic landfills


stones-throw-landfill-20ef944cd09fc077

“The odor was unbearable, as were the flies and stink bugs,” said Brasfield, who sports a greying handlebar moustache and describes himself as a conservative Republican. “The flies were so bad that you couldn’t walk outside without being inundated by them. You’d be covered in all sorts of insects. People started getting headaches, they couldn’t breathe. You wouldn’t even go outside to put meat on the barbecue.”

The landfill, called Big Sky Environmental, sits on the fringes of West Jefferson and is permitted to accept waste from 48 US states. It used a nearby rail spur to import sewage from New York and New Jersey. This epic fecal odyssey was completed by trucks which took on the waste and rumbled through West Jefferson – sometimes spilling dark liquid on sharp turns – to the landfill.

The Mysterious Life (and Death) of Africa’s Oldest Trees


Nature Baobab Tree Africa Tanzania Safari

Baobab tress are fascinating. Some can be more than 1000 years old.

Trees—sometimes felled, sometimes planted, sometimes accidental witness to history—provide a setting always growing imperceptibly in the background. We plant trees for resources, shade, sustenance. We often kill trees with intention and purpose: for shelter, for warmth, for paper, for soap, for winter rituals, for clogs, for furniture. But with baobabs, we’re watching in exasperation as they fold on their own. The description of fallen giant trees struck a chord globally, even though the baobab grows mostly in Africa, Australia, and India. (There are a few in Hollywood, Florida, and in Disney’s Animal Kingdom in Orlando, where the synthetic spectacle—the Tree of Life—lights up in neon and glitz.) Speaking anthropomorphically, the baobab is the charismatic megafauna of botany, so its fall seems to portend our own.

Why Cellular Network Towers Get Disguised as Trees


image

With the rise of mobile phones in the 1980s came ever more cellular network towers, and, of course, not-in-my-backyard (NIMBY) criticisms from nearby residents who saw them as eyesores. Thus, an array of camouflage techniques emerged alongside this expanding technology. Towers were hidden inside church steeples, coupled with water towers, disguised as flagpoles and otherwise made to stand out less in their environments. Of course, there’s not always another structure handy to help hide a tower. So, in the early 1990s, a new idea took root and towers designed to look like trees began to crop up.

A plant that could save civilization, if we let it


legumes_header

Besides being edible and nutritious, any super plant would need to tolerate floods and droughts and be able to survive in a wide variety of climates ranging from arid regions in north Africa to temperate regions in northern Europe. Ultimately, Chory’s goal is to breed plants that grow extra-deep roots with lots of suberin for long-term carbon storage. She estimates that if 5 percent of the world’s cropland, approximately the total area of Egypt, were devoted to such super plants, they could capture about 50 percent of current global carbon dioxide emissions.
