Nearly 33,000 acres of Florida's Everglades National Park were burning yesterday with only 20% of the blaze contained, CNN reports. A dense smoke warning was in effect in parts of southern Florida as flames threatened an endangered sparrow species and private property. The fire is the latest in a series of wildfires sweeping Florida, including one near Daytona Beach that has spread over 12,000 acres. (More Everglades stories.)
