Ecologist 'bursts into tears' seeing endangered gliders using replacement nests

No one knew if this idea would actually work.

When a team of Australian researchers started checking the high-tech boxes they'd installed to help save endangered greater gliders back in 2023, they weren't sure what they were going to find. The hope was that the tree-dwelling marsupials would use them for nesting—a replacement for the tree hollows they normally nest in—but no one knew whether or not the creatures would take to them.

So when Dr. Kita Ashman, Threatened Species and Climate Adaptation Ecologist at WWF-Australia, found a glider in the second box she checked, she was thrilled.

"I just burst into tears, I was so surprised and so happy," she told ABC News Australia.

Greater gliders are nocturnal marsupials that live in old-growth forests of eastern Australia. They have large ears, fluffy fur, long tails, and they can glide up to 100 meters at a time. The species is only found in Australia.

"I grew up looking at greater gliders all throughout the Dandenong Ranges. So they have a really special place in my heart," said Dr. Ashman told ANU.

The special nesting boxes were designed and created through a partnership between Australian National University (ANU), Greening Australia and the World Wide Fund for Nature-Australia after 2019-2020 bushfires destroyed a third of the greater gliders' remaining habitat. The tree hollows that greater gliders rely on to nest can take over 100 years to form, according to ANU, so it's not like they can just find some new trees to live in when their homes are destroyed.

Nesting boxes that are commonly used for wildlife aren't a good fit for greater gliders, as the thin walls and lack of thermal protection can result in gliders overheating. (Heat-stressed gliders will slow their eating, which can be life-threatening, according to ANU.) The high-tech boxes in this project are insulated and include a non-toxic, heat-reflective, fire-resistant coating to keep gliders safe.

"I've affectionately been calling this design the Goldilocks box because we hope it will keep greater gliders not too hot and not too cold and will help to increase the species' resilience in a changing climate," Ashman said in July 2022.

"Producing and installing high-quality nest boxes is costly," added ANU research fellow Dr. Kara Youngentob, "so this project is very important because it will help us understand if expensive interventions like nest boxes are the best use of funding in our urgent mission to save greater gliders."

It appears that their efforts are paying off.

"What we didn't know was whether these boxes worked and whether they have an impact on the glider population," Dr. Youngentob told ABC News Australia. "Much to our delight, within a few months of them going up they are already being used by gliders, so we know the individuals themselves like them and use them."

According to Youngentob, greater gliders are the largest gliding marsupial at risk of extinction. More than 200 nesting boxes have been installed in Victoria's East Gippsland and in Tallaganda National Park in New South Wales. Youngentob told ABC News Australia that this project will help researchers learn more about how many of the species are left in the wild.

The quiet, nocturnal marsupial faces threats from climate change and deforestation in addition to the wildfires that ravaged Australia in 2020. Their population has fallen by 80% in the past 20 years and the species has maintained an endangered status since July of 2022.

"They're a treasure for this country." Dr. Youngentob told ANU. "And I think the more people know about them, the more that they will fall in love with them and want to protect them too."

Greater gliders are endangered in Australia and rely on old-growth tree hollows to make their nests.

What will Earth look like if all its land ice melts? Here's your answer.

Climate change isn't pretty.

A map of the United States post land-ice melt.

Land ice: We got a lot of it. Considering the two largest ice sheets on earth — the one on Antarctica and the one on Greenland — extend more than 6 million square miles combined ... yeah, we're talkin' a lot of ice. But what if it was all just ... gone? Not like gone gone, but melted?

If all of earth's land ice melted, it would be nothing short of disastrous. And that's putting it lightly. This video by Business Insider Science (seen below) depicts exactly what our coastlines would look like if all the land ice melted. And spoiler alert: It isn't great. Lots of European cities like, Brussels and Venice, would be basically underwater.

In Africa and the Middle East? Dakar, Accra, Jeddah — gone.

Millions of people in Asia, in cities like Mumbai, Beijing, and Tokyo, would be uprooted and have to move inland.

South America would say goodbye to cities like Rio de Janeiro and Buenos Aires.

And in the U.S., we'd watch places like Houston, San Francisco, and New York City — not to mention the entire state of Florida — slowly disappear into the sea.

Business Insider based these visuals off National Geographic's estimation that sea levels will rise 216 feet (!) if all of earth's land ice melted into our oceans.

There's even a tool where you can take a detailed look at how your community could be affected by rising seas, for better or worse.

Although ... looking at these maps, it's hard to imagine "for better" is a likely outcome for many of us.

Much of America's most populated regions would be severely affected by rising sea levels, as you'll notice exploring the map, created by Alex Tingle using data provided by NASA.

Take, for instance, the West Coast. (Goodbye, San Fran!)

Or the East Coast. (See ya, Philly!)

And the Gulf Coast. (RIP, Bourbon Street!)

I bring up the topic not just for funsies, of course, but because the maps above are real possibilities.

How? Climate change.

As we continue to burn fossil fuels for energy and emit carbon into our atmosphere, the planet gets warmer and warmer. And that, ladies and gentlemen, means melted ice.

A study published this past September by researchers in the U.S., U.K., and Germany found that if we don't change our ways, there's definitely enough fossil fuel resources available for us to completely melt the Antarctic ice sheet.

Basically, the self-inflicted disaster you see above is certainly within the realm of possibility.

"This would not happen overnight, but the mind-boggling point is that our actions today are changing the face of planet Earth as we know it and will continue to do so for tens of thousands of years to come," said lead author of the study Ricarda Winkelmann, of the Potsdam Institute for Climate Impact Research.

If we want to stop this from happening," she says, "we need to keep coal, gas, and oil in the ground."

The good news? Most of our coastlines are still intact! And they can stay that way, too — if we act now.

World leaders are finallystarting to treat climate change like the global crisis that it is — and you can help get the point across to them, too.

Woman who gets all her food from supermarket dumpsters only spends $100 a year on groceries

"I've only been sick one time because I ate a bad apple."

An abundance of food taken from a dumpster.

In the United States, we have two big problems that should help solve each other, but unfortunately, the problems persist. According to the USDA, it's estimated that between 30 to 40% of the food supply in the U.S. is wasted. So, wholesome food that could help feed families instead winds up in landfills. At the same time, about 18 million households, or 13.5% of the population, are food insecure.

Five years ago, Sofie Juel-Andersen, 30, of Denmark, who was living in Sydney, Australia, was told by her sister that she could save a lot of money and prevent food from being wasted by diving into dumpsters at her local supermarket. Initially, Juel-Andersen was skeptical about her sister’s idea. “My sister sent me a photo of some hidden treasures she’d found dumpster diving. I knew about it, but I’d never seen it as an option to put food on the table,” she told SWNS.

After Juel-Andersen made a few successful hauls and saw the amount of money she was saving, she was hooked. “What I found was insane. It was filled with food—some of it had expired, but a lot hadn’t,” she said. “It was like a treasure hunt for me. I quickly realized that there was so much good food in the dumpsters I didn’t need to go shopping anymore.”

After moving back to Denmark in 2022, she continued dumpster diving and has been so successful that she hardly ever has to shop at the grocery store. She estimates she only spent $100 in supermarkets in 2024, primarily on toiletries such as toilet paper and toothpaste. This allowed the restaurant manager to have a lot more money for traveling.

Her success as a dumpster diver has made her popular on TikTok, where she can share an important message about food waste.


Why do grocery stores throw out good food?

Why are grocery stores throwing away so much good food? “I believe grocery stores throw out food because of the following reasons; the first is there's a small mark on the product or it's in a bag where one item is rotten,” she told Newsweek. “The second is they have a new shipment of a product, so they throw away the old ones which are closer to their sell-by or best-before dates. Thirdly, grocery stores may get rid of one product in a large container where another has been damaged.”

So how does Juel-Andersen avoid getting sick eating food she finds in dumpsters, a lot of it close to or past its expiration dates? "My main source of food is food from the dumpsters, and I've only been sick one time because I ate a bad apple,” she shared on TikTok. “Which was completely my own fault." She added that she avoids eating food that is "moldy, looks bad, or smells bad. I am very cautious of what I take."

Even though dumpster diving should never be the solution to the problems of food waste and insecurity, Juel-Andersen’s brave and creative approach to the problem has inspired an important discussion about sustainability and resourcefulness. Let’s hope that in the future, we can bridge the gap between surplus and need so no food is wasted, and no one goes hungry.
