These microorganism are at the bottom of the food chain, when they die, it doesn't take long for the rest of the food chain to follow. Large increase in salt concentration can cause 75% - 100% death for these microorganisms, The effect of salt is almost immediate. Most of the organism are only one cell big and blow up in contact with increased amounts of salt.

Water insects are also effected by the increase in salt in the environment. The number of insects lowers because the inability for water insects to reproduces in the presence of high salt concentrations. With the decreasing numbers in microorganisms, insects and fish, it is easy to see the effect it would have on the rest of the food chain even though other animal may be more salt tolerable.

Salt pollution also is a major factor to land. It can also be broken up into the effects on soil, vegetation and animals.
