The Pasterze Glacier in a 1900 postcard and in March 2025

125 years ago, the Pasterze glacier in the Austria's Eastern Alps was postcard perfect: Snowy peaks. Windswept valleys. Ruddy-cheeked mountain children in lederhosen playing "Edelweiss" on the flugelhorn.

But a lot has changed since 1900. Much of it has changed for the better. We've eradicated smallpox, Hitler is dead, and the song "Billie Jean" exists now. On the downside, the Earth has gotten hotter. A lot hotter. From June 2023 to May 2024 each month was the hottest ever recorded in the planet's history. July 2023 was the planet's hottest month — ever. Unsurprisingly, man-made climate change has wreaked havoc on the planet's glaciers — including the Pasterze, which is Austria's largest. Just how much havoc are we talking about? Well, this is how the Pasterze Glacier looked in a 1900 postcard:

And this is how it looks now in March 2025:

First measured in 1851, the glacier lost half of its mass between that year and 2008. A marker placed in 1985 shows where the edge of the glacier reached just 40 years ago. You can still see the ice sheet, but just barely, way off in the distance. In between is ... a big, muddy lake. The view from the glacial foot marker from 1995 — 10 years later — isn't much more encouraging. Even in just one year, 2015, the glacier lost an astounding amount of mass — 177 feet, by some estimates.

Overall, it is estimated that the glacier has retracted by 980 feet since the park first opened in 1963.

Ice continues to melt daily, and while the dripping makes for a good photo, it's unfortunate news for planet Earth. Glacial melting is one of the three primary causes of sea-level rise. Pasterze is still technically the largest glacier in Austria and the Eastern Alps at approximately 6.2 miles. And even in its reduced form, Pasterze remains a significant tourist destination.

According to a European Environment Agency report, the average temperature in the Alps has increased 2 degrees Celsius in the last 100 years — double the global average. It's not unreasonable to assume that that's why this mountain hut has been abandoned by the flugelhorn-playing children who once probably lived in it.

Is there anything we can do to stop the Pasterze Glacier from disappearing?

There are efforts underway to save Pasterze and other significant glaciers. However, Gerhard Lieb, the co-leader of the Austrian Alpine Club described the glacier's retreat as "unstoppable" with predictions that it and Austraia's other major glaciers will be gone in as little as 45 years. It would take decades of meaningful counter climate change initiatives, with even the existing ones being too slow for meaningful action, "and the time is up,” Lieb said. “That means nothing can be done anymore.”

Scientists left cinderblocks in a barren part of the sea. 3 months later they were ecstatic.

Coral reefs are dying at alarming rates. Concrete may be a creative solution.

Scientists are turning simple concrete into the building blocks for a healthier ocean.

A viral video has been making the rounds lately that shows a giant (and extremely bizarre) ship opening up at its middle and dropping a metric buttload—that's the official term—of cinderblocks directly into the ocean. The video is fascinating, so much so that I was certain it was AI-generated at first. After all, what kind of ship can part down the middle like that?

Turns out, the video is real! The ship is called a split hopper barge and is often used to transport and deliver dredged soil. Dumping concrete like this looks like the world's worst case of littering, but in actuality, the concrete blocks serve an important purpose that benefits sea life of all varieties.

But how?

For answers, look no further than the GARP — that's the Grenada Artificial Reef Project (also known as the Grand Anse Artificial Reef Project or GAARP).

With coral reefs under threat and disappearing all over the world, the team behind the project came up with an interesting solution they wanted to test out.

In 2013, the scientists placed four concrete pyramids (basically, cinderblocks stacked together into something of a tower structure) in a barren part of the Caribbean Sea. The location was just off the coastal beaches of Grenada.

In just 3 months, the pyramids had attracted tons of marine life.

The block pyramids gave shelter to the animals who otherwise had nowhere to hide, nest, or feed in this part of the water. "An initial growth of algae and colourful encrusting sponge was soon followed by a varied range of invertebrates. These included feather duster worms, lobster, crab, and urchins. Excitement developed as we started to see a range of juvenile fish including squirrel fish, goat fish, grunts and scorpionfish," says the official website.

After a year, word must have spread among the fish, because the simple concrete blocks transformed into "buzzing diverse communit[ies] of marine life."

At around 18 months, things started to get really exciting. Stony and brain corals, described as the "building blocks of coral" began to appear on the pyramids.

Over the following 10 years, the project has exploded with more and more coral growing on the blocks and more fish and other sea life moving in. "Each subsequent year more pyramids have been added to increase biomass. GARP is becoming a balanced ecosystem, home to over 30 species of fish, 14 different kinds of corals and many of the invertebrates and algae you would find on a naturally occurring reef."

Today, there are upwards of 100 pyramid blocks in the location. Other, similar projects are taking place in waterways all over the globe.

GARP/GAARP isn't the first or only project of its kind. Concrete has been shown again and again to make an excellent shelter for marine life and a perfect launching pad for new coral growth.

People have tried other materials before, to varied results. One such project off the coast of Florida in the 1970s utilized millions (!) of old tires in an effort to create new fish habitats. Called the Osborne Reef, the effort is now considered a major ecological disaster as storms and sea currents have tossed many of the tires around, washing them ashore and even damaging otherwise healthy natural reefs nearby. Talk about a backfire. Major clean up initiatives to undo the damage are still underway.

Specialized concrete structures are heavy enough to stay put in rough conditions and are one of the few things that can withstand years and years of being battered by rough, salty seawater without degrading.

Coral reefs are disappearing around the globe at an alarming rate. Physical damage, both natural and manmade, along with pollution, coral harvesting, global warming, and bleaching wreaks havoc on natural ecosystems under the sea.

Coral reefs aren't just there to look pretty. They dampen waves and currents before they hit land, reducing erosion and protecting people who live on the coast. Reefs are home to a huge variety of marine life who use it for shelter and finding food. And, finally, they're amazing destinations for scientific discovery—new species and even medical treatments are being discovered on reefs all the time!

All that and the very existence of coral reefs may be in jeopardy, according to the EPA.

There's no easy fix to this grave problem. Natural coral reefs take thousands of years to grow and mature. So, even with all the cinderblocks in the world acting as growth platforms, it would be impossible for us to replace all the coral we've already killed or destroyed. Saving our oceans must be a multi-faceted effort, with initiatives that combat pollution and rising sea temperatures in addition to creating artificial reefs.

But projects like GARP/GAARP are an awesome start. They may not save the planet all on their own, but if you ask me, those fish look pretty darn grateful for their new home.

Innovative farm in Virginia can grow 4 million pounds of strawberries on less than one acre

This method uses 97 percent less land and up to 90 percent less water than conventional farming.

A new way to grow strawberries with less land, less water, and more berries.

Strawberry farm harvests aren't something most of us calculate on a regular basis (or ever at all), but the numbers from a strawberry farm in Richmond, Virginia are staggering enough to make it worth an old-school word problem. If the average American eats 8 pounds of strawberries a year, and an average strawberry farm yields approximately 20,000 pounds of berries per acre, how many people could a 200-acre strawberry field feed?

I won't make you do the math. The answer is 500,000 people. But what if a crop that size, providing enough strawberries for half a million people, could be grown on just one acre instead of 200? It's possible. You just have to go—or rather grow—up, up, up.

Indoor vertical farm company Plenty Unlimited knows a lot about growing up. In fact, it's their entire business model. Instead of the sprawling fields that traditional farming methods require, vertical farms have a much smaller land footprint, utilizing proprietary towers for growing. Plenty has used vertical farming methods to grow greens such as lettuce, kale, spinach, and more for years, but now it boasts a vertical berry farm that can yield a whopping four million pounds of strawberries on a little less than an acre.

Growing indoors means not being at the mercy of weather or climate unpredictability (barring a storm taking out your building), which is wise in the era of climate change. Unlike a traditional greenhouse which still uses the sun for light, Plenty's indoor vertical farms make use of the latest technology and research on light, pinpointing the wavelengths plants need from the sun to thrive and recreating them with LED lights. Plenty farms also don't use soil, as what plants really need is water and nutrients, which can be provided without soil (and with a lot less water than soil requires). Being able to carefully control water and nutrients means you can more easily control the size, taste and uniformity of the berries you’re growing.

If that sounds like a lot of control, it is—and that idea might freak people out. But when a highly controlled environment means not having to use pesticides and using up to 90% less water than traditional farming, it starts to sound like a solid, sustainable farming innovation.

Plenty even uses AI in its strawberry farm, according to its website:

“Every element of the Plenty Richmond Farm–including temperature, light and humidity–is precisely controlled through proprietary software to create the perfect environment for the strawberry plants to thrive. The farm uses AI to analyze more than 10 million data points each day across its 12 grow rooms, adapting each grow room’s environment to the evolving needs of the plants – creating the perfect environment for Driscoll’s proprietary plants to thrive and optimizing the strawberries’ flavor, texture and size.”

Plenty even has its own patent-pending method of pollinating the strawberry flowers that doesn’t require bees. Even just the fact that this enormous crop of strawberries will be coming from Virginia is notable, since the vast majority of strawberries in the U.S. are grown in California.

Plenty's Richmond farm is currently growing strawberries exclusively for Driscoll’s.

“Partnering with Plenty for the launch of the Richmond Farm allows us to bring our premium strawberries closer to consumers in the Northeast, the largest berry consumption region in the U.S.,” Driscoll’s CEO Soren Bjorn said in a press release. “By combining our 100 years of farming expertise and proprietary varieties along with Plenty’s cutting-edge technology, we can deliver the same consistent flavor and quality our customers love—now grown locally. This new innovative farm is a powerful step forward in continuing to drive category growth in new ways for our customers and consumers.”

Is Plenty’s model the farm of the future? Perhaps it’s one option, at least. The more we grapple with the impact of climate change and outdated, unsustainable farming practices, the more innovative ideas we’ll need to feed the masses. If they can get four million pounds of strawberries out of an acre of land, what else is possible?

Depressed by the state of the world? Deepak Chopra shares the first step to finding joy again.

The author of The Seven Spiritual Laws of Success shares his life-changing advice in an exclusive interview with Upworthy.

It’s becoming increasingly difficult for people to shake the deep-seated sense of dread about where the world is headed. Every day, we are subjected to images of bombs dropping on civilians, massive icebergs falling into the ocean due to climate change, masked men pulling people off the streets for deportation, constant political chaos, and a culture changing so fast due to technology, it’s easy to be overwhelmed.

Added to this is a lingering sense of brokenness that persists from the COVID-19 pandemic era. The result is that in the United States, more people are being diagnosed with depression than ever before. To help our readers break free from the current sense of helplessness, we sat down with Deepak Chopra at Aspen Ideas: Health to hear his thoughts on overcoming depression.

Chopra is a Consciousness Explorer and a world-renowned pioneer in integrative medicine and personal transformation. He is also a Clinical Professor of Family Medicine and Public Health at the University of California, San Diego, and serves as a senior scientist with Gallup Organization. He told Upworthy that the most common problem people ask him about these days is depression.

“It's just people in general right now are stressed, anxious, and depressed. And that's because of all the things that are happening in their environment, social ecosystem, political systems, war, climate change, health,” he told Upworthy. He notes that although tough times aren’t new, modern stress seems to take a deeper toll.

“Because we have modern capacities for war, drones, nuclear weapons, cyber warfare. And for the first time, I think we are risking extinction. [Instability] has been happening since Medieval times. But Medieval tribal bonds and modern technology is a dangerous combination. So it's much worse than it's ever been,” he said.

What's the first step to overcoming depression, according to Deepak Chopra?

Chopra says that those who are experiencing depression or are just feeling down should ground themselves in their “essential being” (more on that later). But, more practically, they should spend time with people who lift them up. “Hang out with people who are joyful with only one purpose: to create joy in the world. Create joy for yourself. Hang out with joyful people and help create joy in the world,” he told Upworthy. “Joy is the only antidote for suffering. And joy is our fundamental state of being. It's not the same thing as happiness, which is the opposite of sadness. Joy is what you see in an innocent child that is happy for no reason whatsoever. It's our fundamental state of being before we get bamboozled by the hypnosis of social conditioning.”

To find out what Chopra means by being “grounded in your essential being,” we consulted his digital twin at DigitalDeepak.AI. Chopra has created an AI that encapsulates all of his teachings throughout his illustrious career, allowing everyone to access his wisdom at any time.


The concept of essential being, according to Digital Deepak:

Being grounded in your essential being is about connecting with the deepest part of yourself—the true self that exists beyond the fluctuations of the mind and the distractions of daily life. It is about recognizing that, at your core, you are pure consciousness —a field of infinite possibilities and potential.

When you are grounded in this essential state, you experience a profound sense of peace and stability. You become anchored in a state of awareness that transcends the temporary and ever-changing nature of the external world. This grounding allows you to navigate life's challenges with a sense of ease and fearlessness, as you are deeply connected to the eternal power within you.


Sometimes, we can become so overwhelmed by world events that it's easy to overlook the basic things we need to be happy and healthy. That's why Chopra's belief in the importance of maintaining positive social relationships with others, especially during stressful times, is crucial to our mental well-being. If you are feeling down, it's essential to get out and spend time with positive, uplifting people. But it's also crucial to get help from a trained mental health professional.
