According to George Woodwel, a researcher with Woods Hole Oceanographic Institute, fish diseases are rampant, but not unexpected. It's all part of the biotic impoverishment of coastal waters due to human-induced chemical, physical and biological changes. This chronic disturbance leads to a simplification of basic structures. It favors small-bodied, rapidly producing organisms, from which come pests of all sorts, including those carrying disease. This harmful dinoflagellate releases toxins which are absorbed across the gills causing asphyxiation, or poison via food chain bioconcentration.
Rivers are the roots of the sea.
Rivers supply the seas with over 1 billion tons of dissolved chemical components and over 10 billion tons of sediments and organic particulates. A new way to curb violence. Research studies indicate that pollutants found in fresh water may lead to a life of crime. The toxic chemicals, particularly heavy metals, can disrupt neurological control mechanisms that inhibit violent urges and make people, particularly children, more violent. Studies on chlorinated hydrocarbons show that attention deficit syndrome in children may be, in part, caused by these chemicals.
