Researchers are studying whether the chytrid fungus -- which has decimated frog and salamander populations around the world -- is being spread among wild amphibians by the release of infected animals bought at pet stores. The fungus has devastated some 200 species globally, and may be responsible for the greatest known disease-caused loss of biodiversity in recorded history.

"For the better part of a decade, Rev. David Hudson has been fighting to uncover what’s polluting the water in his home town."

"Hudson moved to DeBerry, Texas, a poor, predominantly black community straddling the Louisiana border in 2002.
