In the Hackensack river estuary wich crosses the Meadowlands, the salinity of the water is greater than 100 years ago. This is probably a result of a. a significant decrease in sea level at the mouth of the river b. a significant increase in the salt content of the ocean c. a significant increase in pollution from organic chemicals d. damming the river upstream from the Meadowlands Solution Choice c is correct. Reason: With course of industrialization and increase in liquid waste along with chemicals generated from the commericial industries, various water bodies have experienced decline in quality of water in last few decades. The Hackensack river is one such example which has specifically undergone increase in salinity upto 16 times as before and consequently undergo lack in diversity of fauna and flora. The major reason behind this observation is uncontrolled industrialization and pollutant release in the water body..
