Living things need water in their cells. Water is the universal solvent - most of the chemicals a cell needs is dissolved and transported in water. Water is an environment where chemical reactions can occur and water is needed in many of those reactions - like the hydrolysis reaction (needed in the break down of food molecules). If a cell becomes dehydrated chemical reactions slow down. Chemical balance of the cell is changed as waste materials are not removed fast enough, food is not broken down, etc. Water also helps regulate the heat that can build up in a cell during chemical reactions. A dehydrated cell = increase in cell temp. Water content of a cell also affects the pH of a cell environment. Certain reactions occur better at certain pH. Homeostasis is maintaining a balance with the the environment. Without water the balance is upset.
The waters of the Gulf of Mexico looks brown because of the sediments coming from nearby rivers. It is basically an ocean basin, so it receives waters from different bodies of water. These sediments come from decayed matter like rocks, aquatic plants and wastes from aquatic organisms. It can harm freshwater fishes but some plants could thrive in that condition. As for humans, it is not safe to drink the water with high turbidity. The water is deemed not potable because it might contain harmful bacteria that could lead to digestive diseases.
