The Mongols set up a tribute empire called The Golden Horde. Serfdom arose as peasants gave up their lands to the aristocracy in exchange for protection from the Mongols. Moscow benefited financially by acting as a tribute collector for the Mongols. Mongol rule kept Russia culturally isolated from Western European trends such as the Renaissance.
Its a bad idea, because you are taking the saltwater marsh away from the ecosystem... And turning it into a cement covered ground, for more houses... Then the animals (or other things) that live there, will die... and have to find another place to live...
~therefore... The bad thing is, that they shouldnt fill the marsh with dirt, and cement... Because bad things could happen to the creatures that already live there.
