Why sharks and rays keep our oceans alive | Louisa Graf | TEDxDeakin Uni Melbourne
TEDx Talks· 2025-12-22 17:17
You're standing by the ocean and you look down into the water, but it's murky, cloudy, and a little bit sour on the nose. The schools of fish you used to see darting past look sickly, weak, and they're riddled with parasites. The coral reefs are overgrown with algae, suffocating.The seaggrass meadows, one of the planet's most powerful carbon sinks, are stripped bare. And the ocean warms. It feels different on your skin, no longer refreshing.Would you want to swim in this ocean, eat fish from this ocean, or ...

Protecting Colombia’s endangered wildlife with Project SPARROW
Microsoft· 2025-12-19 17:31
We are here at the Magdalena River, one of the most endangered ecosystems in Colombia. There is less than 15 percent left of its original 4,000 square kilometers. Many species only live here, so if these forests disappear, they will disappear from the world.We cannot solve a problem if we cannot measure it. We know that for biodiversity experts to work, they need data. They need to go into the field, install new camera traps, install new acoustic devices, and then come back, sometimes finding out that the c ...

When I was 18 years old, I left home from Surinam to study far away in Europe um to start a university. That fear of the unknown, that leap o ...
The Arribada and The Shores We Share | Maitreyi Manoj Nair | TEDxUWCCR Youth
TEDx Talks· 2025-12-04 17:22
Close your eyes for a moment. Imagine the sound of a million flippers thuing softly against the sand. The moonlights reflecting off countless of determined creatures, each following an ancient instinct, an instinct that's older than civilization itself.This is the Ariada, the great arrival of the olive ridley turtles on the coast of Odisa, India. For three years, I call that coastline home. And as a child, I would stand barefoot in the cool sand, watching the turtles come ashore in waves so synchronized, it ...
