Environment Group Grades Health of the Bay
A report card released by an environmental institute Monday gave the San Francisco Bay one B, three Cs, three Ds and an F.
The grades were based on historical conditions, environmental and public health standards and restoration targets, according to the Bay Institute of San Francisco in Novato.
To measure the health of the bay, scientists spent three years examining such things as wildlife habitat and pollutants, and prepared the Bay Index 2003. Scientists also looked at freshwater flows from the Sacramento and San Joaquin rivers and the numbers of fish, shellfish and the microscopic plankton that feed these higher forms of aquatic life.
