40 percent of world’s population lives in coastal areas. Coastal areas have different characteristics where saline water from sea, its winds carrying salt, salt marshes, inland sea water vegetation , halophytes make a typical ecosystem Man is not master of earth.

What is happening could not happen if we leave 10 km or 20 km of coastal area with natural vegetation .
