摘要

Wetlands are shallow marine waters and wet areas in cluding rivers, lakes and marshes. According to scientists, even reservoirs and paddy fields fall into the category. Wetlands are classified into over 40 types but accounts for only 6% of the earth's total land area. Human beings inhabit by water and grass because wetlands provide us with water and wet soil.
