Freshwater fisheries- these produce about a quarter of all food on earth and bring millions of dollars into the economy each year.
Waste disposal- this is considered an industry somehow, People still dump wastes into our small amount of freshwater resources we have saving lots of money and space but ruining our only water supplies.
There are other that I haven't mentioned but they are too minor to waste time on
