Answer:
The impact of depletion of the fishing stocks.
Step-by-step explanation:
Fishes consume microbes and algae, therefore, if the fishing stocks are depleted there will be an intensive increase in microbes and algae which can cause the water to be poisonous. The depletion of fishing stocks will result in the shortage of food for the bigger sea creatures that come next level in the seafood chain. Consequently, the depletion of fishing stocks will cause a depletion of other sea species as well. It will ultimately affect the ecosystem and subsequently humans, who are dependant on the seafood for their livelihood.
