Alien InvasionStreaming Video - 2012
Sometime in the 1940s a brown tree snake hitched a ride aboard a U.S. Air Force plane in New Guinea traveling across the Pacific to the island of Guam. As a result, Guam lost all its native bird life. More recently, an African fungus crossed the Atlantic to cause a damaging disease in Caribbean coral, and the European gypsy moth has been steadily transforming America's forests. However, these occurrences are far from unique and are in fact becoming more common with each passing year. In Alien Invasion, a part of the PBS Scientific American Frontier series, host Alan Alda examines how globalization of trade and travel has brought increased threats from alien species: plants, animals, insects, and diseases that wreak havoc in defenseless regions.
