Ecosystem scientist Yadvinder Malhi takes us on a jaw-dropping journey through the hidden flows of energy that make life on Earth tick. From sun-soaked forests to tropical islands, he shows how his team measures the vibrancy of ecosystems across the world. This complex web of energy isn’t just nature’s masterpiece, he says — it’s a lifeline for all of us that call this planet home. (Recorded at TED Countdown Summit 2025 on June 18, 2025)

    The blend of AI sensing and traditional field counting feels like the right direction: high-tech measurement, grounded in real-world ecology. More talks connecting those dots, please.

    Wow. Nice story but the stars do the work for the planet not the animals … we have left our mark, however;)

    Maybe this vibrancy and energy is what on a spiritual level is perceived as the Great Spirit or the soul of a place?

    Are people working to restore / re-wild the islands that have been taken over by invasive species? Is there an active process making that happen?

    I did a lot of what we called bush regeneration in Australia for several years… It’s very satisfying work, and you can really see the results over a period of time as the native species may adapt and take over again. All the principles of doing this work have stayed with me for the rest of my life so far….. And continually grow in my understanding of the complexities of nature !
    Thank you so much for this brilliantly presented explanation of biodiversity, with clear scientific understanding , with great examples through the photos.

    Such a powerful explanation of how nature’s energy web keeps our planet alive. Truly eye-opening!

    A forest isn’t just resources — it’s an ancient, living network of life, communication, and quiet miracles we’re only beginning to understand

This week’s guest is Ayal Yogev, co-founder and CEO of Anjuna Security, who has experienced both sides of the startup journey: scaling quickly during the boom years and then making the incredibly difficult decision to lay off a significant portion of his team when the market shifted.

From growing to 75 employees to scaling back and rebuilding, Yogev learned firsthand that the hardest part of leadership isn’t hiring fast, it’s making tough decisions with care, transparency, and integrity.

In this episode, Isabelle Johannessen and Yogev unpack what it really means to lead through layoffs with compassion and how founders can support their teams even in the most challenging moments. They also explore the lessons learned from scaling too quickly and how to build a more resilient company the second time around.
