For the last 50 years, Florida’s governors have been reasonably responsible stewards of the state’s fragile environment. They initiated efforts to clean up rivers and bays, buy and preserve millions of acres of sensitive land, manage growth and preserve the Everglades. Developers and agricultural interests still got their way too often in the state’s boom-or-bust economy, but Tampa Bay is cleaner and more land is protected from development than a generation or two ago. In just four years, Gov. Rick Scott has put those accomplishments at risk.
