Restoring Damaged Rivers

A team of diver/scientists explores Florida’s St. John’s River from its source and along its tributaries until it empties into the Atlantic. They go below and above the river to show how humans have damaged watersheds. Agricultural fertilizer runoff often causes eutrophication (algae bloom, species die-off), lawn sprinkling does unrealized damage, and government flood control projects have had disastrous unintended consequences. Now, farmers, citizens, and governments are taking corrective action to restore natural processes that are as necessary to human civilization as to wilderness.
