In Uncertain, the weevil's a savior

"Perhaps the truth depends on a walk around the lake." 11/1/17 Fear No Weevil: Taking on the World's Worst Weed Salvinia is a tricky beast—it doubles in size every four-five days, has tentacles that loom underneath, and chokes up waterways, making it impossible for wildlife to grow or boats to sail. It's a monster currently devastating Texas's picturesque Caddo Lake. But, never fear, the weevil is here.  Exploring the Unknown Depths of Mexico's Caves Caves are full of untold mysteries, and Carlos Zorrilla is determined to uncover them all. The speleologist and all-around adventurer has already explored 230 of the 460 caves in San Luis Potosí, Mexico, but there are many more that remain undiscovered.   This Great Big Story was made in partnership with Toyota Camry.
