80% of Rivers Are Suffocating — Here's Why

追加: 2026-05-25

[00:00:00]You think rivers are dying from pollution? No, >> [music] >> they're literally suffocating. Right now, eight out of 10 rivers on Earth are losing oxygen, and most people have no idea it's happening. [music] A massive global study tracked 21,000 river systems over nearly four decades, and the results were terrifying. Here's the problem: warm water can't hold oxygen. Just like a warm soda goes flat fast, rivers are doing the same thing.

[00:00:24]Climate change heats the water, the oxygen escapes, and entire ecosystem starts silently breaking down. Fish can't breathe, insects disappear, food chains break, and this is the scary part nobody talks about. [music] Rivers help control local rainfall and weather. When river ecosystems break down, they stop regulating the freshwater cycle they've always been part of. That [music] has consequences we're only beginning to understand. We treat rivers like background scenery, but they're basically the planet's [music] circulatory system. We built every civilization next to a river. Maybe it's time we started paying attention to what's happening inside them. What's the nearest [music] one to you? And when did you last actually look?
