It's not been a good year for Florida's citrus industry. The U.S. Department of Agriculture reports that, for the second year running, the orange crop is expected to be almost 10 percent lower than the previous year.

 

The culprit is citrus greening, a disease that has devastated Florida's oranges and grapefruits, and has now begun to spread in Texas and California.

 

Back in the 1950s and '60s, the Florida Citrus Tower was one of the Orlando area's most important tourist attractions.

 

It all ended with a series of freezes in the 1980s that devastated citrus in Central Florida. In the '83 freeze, 300,000 acres of mature, fruit-bearing orange and grapefruit trees died in a single night. Growers eventually recovered by moving and replanting groves further south.

 

Citrus greening poses a similar crisis for growers, but one for which so far, there is no solution.
