From slime molds that can map efficient transport systems to fungi that help create sustainable materials, textiles and food, mycologist David Andrew Quist shows how nature can help us solve some of our world’s biggest challenges. In his TED Talk, he explains how looking more closely at fungi — and the skills shaped over billions of years of evolution — can help us rethink systems that are more regenerative and in harmony with the planet. “The most amazing fungal discoveries are still waiting to be made,” he says. “We’re only scratching the surface of what we might be able to achieve with the help of fungi.”

If you like chocolate, peaches, coffee or salmon, you might want to watch this. Rising temperatures are putting some of your favorite foods at risk — and could fundamentally change what ends up on your plate. That’s why culinary entrepreneur and former White House chef Sam Kass (@samkassdc) is holding special events to help raise awareness. The good news? There are changes that can be made right now to support farmers and help prepare our food systems for this new reality. Visit the link in @TED’s bio to watch his full @TEDCountdown talk.

“We only wear 20 percent of our wardrobe,” says digital fashion entrepreneur @karinnagrant. In her TED Talk, she explores how digital fashion could help reduce clothing waste, overproduction and returns — through virtual samples that prevent excess inventory and digital wardrobe tools that help people rewear and repair what they already own. “Digital fashion could also make us be more sustainable,” she says.

If you feel like your allergies are getting worse every year, you’re not imagining it. On the latest episode of TED Health, immunologist Dr. Zachary Rubin (@rubin_allergy) tells host Dr. Shoshana Ungerleider (@shoshanamd) why pollen seasons are getting longer and more intense — and the many other changes that might affect your health. Visit the link in @/TED’s bio to listen to the full conversation.

“For all that’s ever been said about climate change, we haven’t heard nearly enough about the psychological impacts of living in a warming world,” says science writer Britt Wray (@unthinkable.earth). In her TED Talk, she explores how anxiety, grief and hopelessness can impact our mental well-being and shape the way people move through the world. Wray explains why mental health care — alongside self-care, community, activism and honest conversations — matters just as much as policy solutions. Want to learn more?

Imagine visiting a wildlife sanctuary from your couch — without disturbing a single animal. In her TED Talk, creator and conservationist @maya_higa introduces some of the rescue animals at her virtual education center Alveus Sanctuary — from a cow named Winnie the Moo to marmosets named Appa and Momo — and explains how live-streaming these adorable creatures to millions of viewers has become a powerful way to spread the message of conservation worldwide.

Music doesn’t just reflect society — it shapes it, says social entrepreneur Samir Ibrahim (@samiribrahim) . In this TED Talk, he shows how hip-hop has turned complex issues like mental health and social justice and made them part of everyday culture and conversation. He suggests the climate movement needs a similar shift: from something we “talk about” to something we live, create, and hear in culture.

Most people are taught to think in “win-lose” terms — where success comes at someone else’s expense, says John Mackey, cofounder of Whole Foods. But he believes there’s a better way: a “win-win-win” mindset that looks for solutions benefiting individuals, businesses and the larger community all at once. In his TED Talk, @iamjohnmackey reflects on how a devastating flood nearly destroyed the first Whole Foods store — and how the response from employees, customers, suppliers and neighbors completely transformed how he thought about business, leadership and long-term success. From ethical supply chains to creative problem-solving, he explores how shifting beyond self-interest can help us make more sustainable decisions — for people, businesses and the planet.

The Sahara Desert is one of the most extreme environments on Earth, and one of the most abundant sources of solar power — receiving more than 100x the energy needed to meet the world’s electricity demands. So why don’t we cover the desert in solar panels? In this @tededanimation, we explore why turning that potential into reality is more complicated than it sounds — from efficiency limits and extreme heat, to grid storage challenges, ecosystem disruption and global infrastructure constraints.

What if your city could heal itself the way your skin does? In his TED Talk, scientist and engineer Mark Miodownik introduces a new class of materials, “animate matter,” that can sense damage, self repair and even biodegrade when they’re no longer needed. He explains how instead of a world built on constant repair and waste, he imagines a future where roads, bridges and buildings behave more like living systems, restoring themselves and reducing pollution at the source. “Our job wouldn’t be constantly repairing things, laboriously throwing things away and remaking them,” he says “our jobs would be more like gardeners.” Visit the link in bio to learn more.

Should fossil fuel companies be part of the green energy transition? Not if they keep building new infrastructure and lying to us about it, says activist @luisaneubauer. In her TED Talk, Neubauer shares the urgent message that in order to build a more resilient, safe and fair future — we must confront the realities of the oil and gas industry and be prepared to act without them. “Fossil fuel industries are expanding everywhere around the world,” Neubauer says. “And dancing on our chances to create anything like a climate justice world.” Visit the link in bio to watch her full TED Talk.

How do you fix a city on the brink of ecological collapse? 400 years ago, rapid growth in what is now Tokyo led to deforestation, timber shortages and flooding — but through innovation and adaptation, it transformed. In this TED-Ed animation, we explore the city’s massive reforestation efforts, early circular economy systems and the cultural shift toward repair and reuse that helped reshape the city.
