VOA慢速英语 改善沼泽地国家公园状况

　　VOICE ONE:

　　Another threat biologists have been battling for years in the Everglades is the area's population of Burmese pythons. Officials believe there are as many as one hundred fifty thousand of these large snakes in the Everglades. But the snakes are a foreign species, native to Southeast Asia. Owners of pythons left their unwanted snakes in the Everglades years ago.

　　Biologists say adult pythons are able to eat small deer and bobcats. When pythons are found in the Everglades, they are often killed. Scientists are now experimenting with other ways to remove the snakes, including trapping methods and offering payments to hunters.

　　The future of the Everglades is not clear. However efforts to protect the area are continuing so people that from all over the world may continue visiting this biological treasure.
