While the number of cod in the North Atlantic has greatly decreased, the number of seals has increased from 1.5 million to about 2.5 million. Some people think that seals are responsible for the reduction of cod, but seals rarely feed on cod
Before the increase in the number of seals, the number of cod in the North Atlantic decreased greatly.
it is impossible that a large increase in the number of seals has led to a significant decline in the number of cod.
