Answer :
Pollution of water bodies due industrial wastes kills aquatic organisms and this disrupts food source for humans.
What are the effect of silt on aquatic organisms?
Silt refers to small fine particles of sand or mud that forms a suspension in water.
Silt in oceans usually come from rivers opening into the sea
The silt suspended in the water surrounding a coral reef near the coast of a small island community in the Caribbean Sea will originate from rivers and streams opening into the sea.
The silt will reduce the population of algae on the coral reef as they increase water turbidity.
This will reduce fish population in the area and the food source for humans.
Industrial wastes are a source of mercury in lakes.
The presence of mercury will poison the lake and kill the fishes in the lake.
It will also make the water unfit for drinking by humans.
Therefore, pollution of water bodies kills aquatic organisms and this disrupts food source for humans.
