c. change to the landscape from construction

Explanation:

There are various natural and human-involved factors that are responsible for the change in the ecosystem. An increase in the human population, deforestation, change in the climatic conditions, and global scarcity of natural resources are some of the main reasons behind the environmental crisis. The drastic alteration in the landscape because of the construction have major effects on the environment. There are various setbacks to this factor. Some of them are deforestation, rapid fall in the vegetation and wildlife, soil erosion, and pollution.

poor water quality affects most estuarine organisms, including commercially important fish and shellfish. the pollutants that have the greatest impact on the health of estuaries include toxic substances like chemicals and heavy metals, nutrient pollution (or eutrophication), and pathogens such as bacteria or viruses.
