Show Notes

In today’s episode, we journey to the heart of the Amazon Basin—home to the largest freshwater system on Earth. These waterways don’t just support rich biodiversity—they’re a vital source of food and nutrition for millions across South America, where fish are often the most affordable and accessible source of protein. 

But this life-sustaining resource is under threat. Mercury contamination, overfishing, and the pressures of a globalized food market are putting fish populations—and the health of the people who rely on them—at risk. In this episode, we explore how conservationists are working to reimagine food systems in the Amazon—blending traditional knowledge with science to protect rivers, restore fisheries, and ensure a healthy, sustainable future for communities and ecosystems alike.
