What's all that smoke out west? Watch this video

David Fleshler at the Sun Sentinel has an excellent news story on the controlled burns going on this week. His article includes a video of Serena Rinker, the spokeswoman for the Loxahatchee National Wildlife Refuge, who explains why this action is necessary. From the text of the story:

     Smoke will rise over the Everglades of western Palm Beach County Wednesday and Thursday, as wildlife managers begin burning 12,000 acres of freshwater marsh to improve wildlife habitat and reduce the risk of future fires.
     The Loxahatchee National Wildlife Refuge, which runs west of U.S. 441 from Boca Raton to Wellington, plans to conduct the burns across an arc of wetlands running from west of Delray Beach to west of Lake Worth, along the canal running north and south near the refuge's border.
