Nutrient-rich sewage can pollute and overnutrify estuary waters.

Overnutrified estuary waters cause algae to proliferate.

Abundant algae can be a food source for microorganisms that are toxic to fish.

These microorganisms kill most fish in the estuary.

Abundant algae in an estuary can cause most fish in the estuary to die.

Overnutrified estuary waters can cause most fish in the estuary to die.

Nutrient-rich sewage pollution can cause most fish in an estuary to die.

Unsupported. Nutrient-rich sewage can kill most fish in an estuary, but we don’t know that it’s more likely to than other forms of pollution.

Unsupported. Abundant algae can be a food source for toxic microorganisms, but we don’t know that it causes toxic microorganisms to reproduce more quickly than other types of microorganisms.

Unsupported. Nutrient-rich sewage can harm fish in estuaries by causing algae to grow, which feeds toxic microorganisms. But it might harm fish in other ways too.

Unsupported. Overnutrified waters do cause algae to proliferate, but it might proliferate in other conditions too.

Very strongly supported. Overnutrified estuary waters cause algae to proliferate, which can then feed toxic microorganisms that kill most fish in the estuary. So, nutrient-rich sewage pollution can cause the death of most fish in an estuary.
