Dear EarthTalk: The recent explosion at a West, Texas fertilizer plant that killed many people really alarmed me. Places like this must exist near many communities around the country. How do I know if my own community might be at risk of a similar disaster? – Mary Cyr, Sarasota, FL
A devastating drought consumed nearly all of Texas in 2011, killing livestock, destroying agriculture and sparking fires that burned thousands of homes. It was the worst single-year drought in the state's recorded history.
Just off the side of the road in rural southern Texas is a large beige building that looks a lot like a prison. Fences and tall walls mark the outside. Inside, the doors slam and people sit in control booths at the end of long concrete hallways.
But just a little farther into the facility, the door opens to a courtyard in the center of the complex, and there, things begin to change. There's a soccer field, a pavilion and a gymnasium. There's also a walk-up pharmacy and commissary. All of it is guarded by officers in polo shirts.
