They’re Healthy. They’re Sustainable. So Why Don’t Humans Eat More Bugs?

February 26, 2021 at 08:01PM Sylvain Hugel is one of the world’s foremost experts on crickets of the Indian Ocean Islands . So when he received an email from a fellow entomologist in March 2017 asking for help identifying a species in Madagascar that could be farmed for humans to consume, he thought it was a joke. “I’m working to protect those insects, not eat them,” the French academic responded tartly. But the emails from Brian Fisher , an ant specialist at the California Academy of Sciences, in San Francisco, kept coming. Fisher had been doing fieldwork in Madagascar when he realized that the forests where both he and Hugel conducted much of their research were disappearing. Nearly 80% of Madagascar’s forest coverage has been destroyed since the 1950s, and 1-2% of what remains is cut down each year as farmers clear more trees to make room for livestock. The only way to prevent this, Fisher told Hugel in his emails, was to give locals an alternative source of protein.

A Climate Change-Induced Landslide Is Wreaking Havoc on Denali National Park

September 07, 2021 at 07:24PM For decades, the rangers at Denali National Park in Alaska were easily winning their battle against a slow-moving landslide underneath the park’s only road. Now, due in part to the effects of climate change, they are losing very badly. This summer, the National Parks Service has been frantically dropping 100 dump-trucks-worth of gravel every week on the top of the Pretty Rocks Landslide in an effort to keep up with its accelerating pace, which is the result of rapidly thawing permafrost in the country’s fastest-warming state . Two weeks ago, as the landslide hit unprecedented speed, causing the ground around it to undulate with each passing truck, the team conceded defeat and closed the back half of the park weeks earlier than anticipated. The closure is bad news both in the short term—with hundreds of camping and hotel reservations cancelled on a local economy that depends on tourism—and a scary omen for an entire state that rests on similarly t

Depression Is a Pandemic. Let’s Use the Lessons of COVID-19 to Find Treatments

May 17, 2021 at 10:50PM A version of this article also appeared in the It’s Not Just You newsletter. Sign up here to receive a new edition every Sunday. This week, we have a special Mental Health Awareness Month edition of It’s Not Just You. In addition to the piece below, you can read a guest essay from Ciara Alyse Harris , one of the stars of the hit Broadway show, Dear Evan Hansen here. My dad, who was always intuitive, told us he saw that my little sister’s depression had returned when he printed photographs he’d taken of her. “I could see it in her eyes, like a ghost,” he said. It was an observation born of love and experience, not science, but not wrong. Until recently, major depression has felt like a ghost disease–invisible but devastating. It’s a disorder that still affects millions every year–one in four of us will suffer a depressive episode in their lifetime. Despite those numbers and the fact that humans have been documenting and speculating about it fo
