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.
I think the answer is B. Geographers use different kinds of maps, depending on the subject they are studying. <span />
Precise knowledge of location, estimates of size, and general sense of connection between places.
They are the maps in our head, so when you think of a neighborhood or states, you can think of where they are positioned and how to get there
they help navigate areas like the kitchen, states, towns, countries and so on
