Florida’s Sinkholes Are Draining - Scientists Fear What’s Buried Beneath the Surface

Scientists are sounding the alarm as Florida’s landscape undergoes dramatic shifts. In North Florida, severe droughts are causing iconic karst lakes like Lake Jackson to completely drain overnight through sudden sinkholes opening up in the limestone floor. But 300 miles south, a completely different water story unfolds: an ancient civilization built a massive 125-acre island empire out of millions of oyster shells without ever planting a single crop.

Welcome to Discover Tube, where we go beyond the headlines to track how geology, climate, and ancient history collide. In this video, we explore Florida's extreme water crisis of 2026, the mechanics of underground karst systems, and the engineering marvels of the Calusa kingdom.
