FROGS: The Thin Green Line

Frogs have been here for 360 million years and have evolved into diverse creatures. However, one-third of amphibians have been lost. Nature explores frogs, Sunday, April 12th at 7:00 p.m. on KUAT6 and HD.

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, and important medical cures are vanishing.

Rare Golden Frogs are found only in captivity

Frogs may seem small and insignificant, but their bodies may hold the key to important new discoveries in medical research. Scientists are finding that chemical compounds found in frogs’ skins can be used to treat pain and block infections, and are even being explored as HIV treatments. Our chances for the discovery of future medical miracles may be slipping away with the disappearance of these tiny creatures in our midst.

Their impact on the world’s ecosystems is great. Frogs sit right in the middle of the food chain, and without them, other creatures are disappearing, too. We are only just beginning to understand what life may be like without them. The race is on to stem the tide – before the next frog crosses the thin, green line.
