Nitrogen pollutionA key focus (and concern) of staff at Buzzards Bay Coalition is nitrogen pollution of the bay and ocean, said Rachel Jakuba, the coalition's science director. \"What happens with nitrogen pollution is it’s fertilizing the ocean,\" Jakuba said. In addition to the potential loss of habitats, nitrogen pollution can cause too much algae. Oceans are also affected by nitrogen pollution, particularly in coastal areas, according to the National Oceanic and Atmospheric Administration (NOAA). Like Jakuba, she said nitrogen pollution further stresses the ocean system and must also be addressed by municipalities.
