Explanation / Answer
1) Boston harbor was on of the polluted and dirtiest harbour. But now it became as a wornderful place. It is really the US environmental success.

These are all very toxic to the life of natural creatures. The reduction of these harmful sources may rise the number of different plant and fuanal species in water.

So all these people commertial process may cause the decreasing of the quality of waters. So we must control the manmade pollutant processes and must monitor the species behavior also.
