John Teal and Mildred Teal's article is about the ecological significance of salt marshes. Salt marshes vary depending on the region upon which it is found. In the north the marshes are covered in a dense grass. The roots bind the wet mud into a firm surface. In the south the marshes are covered by only one grass which is much more separated than in the north. The roots however are developed into an intricate mass holding the squishy mud together in a layer that floats above a more liquid layer. At low tide the salt marshes is a vast field of grasses, but at high tide it becomes a floating sea of grasses where much water is visible. This environment provides a refuge for marsh animals that cannot stand submersion in salt water.
We are destroying these marshes by dredging, filling, and building. We also destroy them indirectly via pollution. We need to implement a method of preserving these marshes which includes safeguards against increased pressures for further development due to our ever increasing population.
