An increase in fertilizers on the farm are causing increasing amounts of algae in the lake nearby, thus causing a decrease in the number of fish in the lake.
If fertilizers are added directly to the lake, there will be a significant increase of algae in the lake. The increase of algae in the lake will cause a decrease in fish.
One question I have is whether or not the algae have killed off all potential fish to thrive in the lake. If between the farmer and the algae all of the fish have been exterminated then the lake will no longer have fish in it without another source being introduced.
