This story was printed in August 2010. In response to the tragic sinkhole event in Tampa, Fla., on March 1, we are reposting this story.
Sinkholes are a natural part of Florida’s landscape, forming when rainwater levels fluctuate. They've occurred naturally for millions of years and they haven’t been a big problem for humans until recently: Florida’s population has increased from fewer than 8 million in the 1970s to just shy of 20 million today — and farmers, snowbirds and Mother Nature have begun to engage in an increasingly acrimonious water war. The addition of humans to the landscape has made the situation increasingly volatile. Now, sinkholes open up seemingly — or literally — overnight. When a sinkhole opened up in a cow pasture, few people cared, but now if one opens up under somebody’s house or under Interstate 4, we pay attention.
