Letter: Spread of exotic species must be stopped

To the editor,

Environmentally there have been many horses out of the barn before the door is closed. The capture of big-headed carp in Minnesota waters is a recent example of the fallout from faulty monitoring and inaction to prevent such occurrences.

Hopefully, something will be done to contain the spread of some of these exotic species. Past experience forces one to be pessimistic, however, as we seem to be burdened with the pound of cure when the ounce of prevention was rejected as too costly or unnecessary.

Electric barriers to prevent further spread of invasive species may seem expensive, but they may well be the ounce of prevention that legislators can approve before adjourning. Fish can travel long distances before next year's session. You could contact your legislators about the urgency of this problem.
