Conserving water is an easy way to prevent water pollution

If this is a true or false question then it is false because conserving water means you are using less of it to save it, but it does not prevent water pollution.  Water pollution is when clean water becomes contaminated and no longer clean, so trying to conserve water has nothing to do with polluted water.

fluid balance is an aspect of the homeostasis of organisms in which the amount of water in the organism needs to be controlled, via osmoregulation and behavior, such that the concentrations of electrolytes (salts in solution) in the various body fluids are kept within healthy ranges. the core principle of fluid balance is that the amount of water lost from the body must equal the amount of water taken in.
