In some third world countries "cyanide fishing" for aquarium trade is allowed. Cyanide fishing uses the cyanide to "stun" fish and make them easy to catch. But the cyanide combined with handling stress has led to a mortality rate in the captured fish somewhere between 60% and 80%. Knowing this, how might this method impact the environment?
A) Cyanide is a safe chemical, so there will not be any effect on the environment.
B) Increase cyanide levels in the water will increase the biodiversity in that area.
C) Since so many fish are being caught, there is more room for predators to flourish.
D) It could lead to over fishing, since more fish have to be caught due to the high mortality rate.
