Large-scale die-offs of frogs around the world have prompted scientists to take desperate measures to try to save whatever populations they can.

Nature "Frogs: The Thin Green Line" airs Wednesday, March 19 at 8 p.m. on WXXI-TV. Frogs have been hopping the planet for more than 350 million years. They've evolved into some of the most wondrous, diverse and beloved animals on earth. Suddenly, they're slipping away.

We've already lost one-third of our amphibians and more are disappearing each day. Some say it's the greatest extinction since the dinosaurs. Ecosystems are beginning to unravel, important medical cures are vanishing and we're losing a dear old friend. It's a global crisis, mobilizing scientists around the world to stem the tide — before the next frog crosses the thin green line.
