Of concern around large bodies of water now, is unshielded lighting used around boat docking areas. Safety in navigating boats into glaring lights is the main problem. Other problems include disruption of nocturnal wildlife, birds, and fish that live in these areas, and polluting of the night sky to those who come to water's edge to enjoy the stars.
Awareness is increasing at the state level and perhaps soon legislation will prevent or reduce this disruption of the night time environment. Without, may I add, taking away anyone's rights to light up their own pier or boardwalk!
