Question

1. please pick a specific parameter that demonstrates that the condition of boston harbor is better than is was 25 years ago(and cite the sourses of his data). present this data and explian why this data supports your cliam that boston harbor is better now . how are ecosystem functions improved?

2. what could you do in the future increase the quality of boston harbor with respect to your parameter? what could levels of the parameter given above be like 25 years into the future .how clean can boston harbor become (with respect to your measurement)? what controls the trajectory of his parameter? please specific

Answer 1

1. The biomass of phytoplanktons has improved considerably over the past decade in the waters of the Boston harbor. This parameter demonstrates that the condition of Boston harbor is better than it was 25 years before. The functions of ecosystem has also improved. This can be demonstrated by measuring the following phenomenon,

• Dissolved oxygen concentration
• Nitrogen content
• Decrease in hardness of water
• Decrease in pathogenic bacterial content

2. In future, the discharge of sewage effluents should be prevented from drainaging into the sea water directly without treatment. This would increase the dissolved oxygen content and thereby mass of phytoplanktons. The trajectory of this parameter would be controlled by the amount of sunlight received and nitrogen content in water.
