Bob,
That's a pretty good video. Very informative. We have the same problems here in Lk. Pontchartrain. Farm run off and urban pollution has done its damage over the years. Every year, like now, when the River flows into the Lk. we can expect an algae bloom. Same problem--dead crabs, clams, oysters and fish.
Just think. Y'all have 4 or 5 states that have runoff into the Bay. Sitting at the bottom of the river chain we have runoff from Canada to Louisiana. Think of all the N and P we have to deal with not including all the chemical plants. Besides that its a great video about a whole lot of [curd].
