Explanation:

A harbor is a place near the sea shore where the ships and boats can be tied. This region remains protected against the high tides and bad weather conditions.

The building of the harbor may lead to the clearance of the vegetation cover near the shore. This may affect the environment. The impact of new harbor will be determined by the environmental protection agency. This is an organization which deals with the issues related to the environment. It studies the changes in the environment caused by the living and non-living factors. Living factors include the human intervention. Non-living factors include the environmental calamities such as earthquakes, volcanic eruption and others.
