I’m hoping your piece on the algae bloom in Casco Bay (Sept. 26) serves as a wake-up call to all of us who are dog owners and/or are responsible for lawn care.

When we fail to clean up pet waste, and continue to use pesticides and herbicides on our gardens and lawns, the excess nitrogen runoff is not just unsightly. It’s also a threat to Maine’s shellfishing industry and the overall health of Casco Bay.

We all need to do our part.
