Biscayne National Park - Environmental Factors

Biscayne National Park by National Parks Service

John Donne wrote that "no man is an island," and the same can be said for National Parks. While all parks are affected to some extent by what goes on in adjacent areas, the situation is magnified in a marine park where water flowing across boundaries can provide easy access for pollutants, exotic species, and large numbers of visitors not confined to traditional throughways like trails and roads.
