How AI is unearthing hidden scientific knowledge | Sara Beery
Ecologist and AI researcher Sarah Beery explains how vast ecological databases like iNaturalist contain far more information than simple species sightings, including individual identification, species interactions, vegetation, and food webs. She describes how her team at MIT built an AI-powered system called Inquire that lets scientists search millions of images using natural language queries to rapidly extract research-ready datasets, dramatically accelerating ecological discovery. The talk closes with a call for widespread citizen participation in data collection to help build a more complete, actionable picture of life on Earth and support conservation in the face of the biodiversity crisis.
The army of autonomous robots restoring nature | Tom Chi
Impact investor Tom Chi challenges the popular belief that economic growth must come at the expense of nature, arguing instead that the economy is physically a subset of the ecology because everything is ultimately mined or grown. He quantifies the scale of current extraction and describes how outdated industrial processes damage ecosystems, then presents three key shifts: closing material loops through advanced recycling, transforming agriculture with regenerative practices and AI-guided breeding, and using robotics for large-scale restoration on land and underwater. Through concrete examples-from battery recycling and adaptive crops to mangrove-planting drones and a low-cost coral and seagrass-planting robot-he illustrates how modern technology can actively repair ecosystems while supporting a resilient future economy.
How to see (and stop) deforestation from space | Tasso Azevedo
Land reformer Tasso Azevedo describes how the MapBiomas Network turns decades of satellite imagery into detailed, legally robust land-use maps to expose and curb deforestation in Brazil and other tropical regions. By integrating high-resolution imagery, property registries, and protected area data, the project has dramatically increased enforcement against illegal deforestation, redirected finance away from destructive operations, and supported a wide range of environmental and social applications. The talk also highlights successful action against illegal gold mining and outlines plans to expand this collaborative mapping approach to cover most of the world's tropical forests.
These AI devices protect nature in real time | Juan M. Lavista Ferres
Host Elise Hugh introduces a TED talk by Juan M. Lavista Ferres about how a new AI-enabled device network called Sparrow can transform conservation work. Lavista Ferres explains how conservationists currently rely on slow, labor-intensive data collection and shows how Sparrow uses solar power, edge computing, and satellite connectivity to process images and sounds in real time. He describes how this system can automatically identify individual animals, analyze acoustic biodiversity, detect wildfires early, and drastically shorten the time between data collection and action, potentially making the difference between species survival and extinction.
How to measure the planet's heartbeat | Yadvinder Malhi
Ecosystem ecologist Yadvinder Mali explains how he and colleagues measure and map the flows of energy, carbon, and nutrients that sustain ecosystems, from forests and soils to coral reefs. He introduces the idea of "vibrancy"-the complexity and spread of energy through many species-as a key determinant of ecosystem health and resilience. Using examples from English woodlands, savannas, and tropical atolls, he argues that valuing nature only for carbon undermines this vibrancy, and that working with the wild energies of the biosphere gives both ecosystems and human communities their best chance to adapt to climate change.
How satellites are supporting farmers across Africa | Catherine Nakalembe
Satellite food security specialist Catherine Nakalembe explains how she uses satellite imagery and machine learning to map and monitor crops across African countries, and why many existing models fail when applied to smallholder farms. In a follow-up conversation with TED Fellows Program Director Lily James-Olds, she describes the gap between powerful data systems and farmers' realities, the importance of ground-based data and local context, and her efforts to build practical, human-centered ways to turn drought and flood information into action. She also shares a grassroots project to establish soil moisture calibration stations in Africa and reflects on the institutional and financial barriers, as well as the sources of hope that keep her pursuing this work.
