Every day, a certain farm that raises freshwater fish generates several thousand liters of waste water, which is discharged into a nearby river and replaced with fresh water from further upstream. explain why this process is not sustainable. describe a more sustainable process for handling waste water.

The process is not sustainable because by polluting the streams and freshwater lakes can badly cripple whole ecosystems by killing certain type of fish or anything that lives in the waste. So a more efficient process in my opinion  would probably be to use the waste as a compost of some sort because fish waste has a bunch on nitrates in it which in fact would be really good to put in soil or even water plants with.

Please  mark and rate if this helps.
