heres a basic cliffnote on cod and seals , when we started mass fishing we also killed lots of seals , so when we started commercial fishing and such , no matter how many fisah we caught it didnt dent the population ( because we were killing seals at the same time and they eat cod ) so the fish were basically thriving because we were killing so many seals, it wasn't until we stopped killing seals that cod started to severely decline , then the seal population boomed and we suddenly had a big problem , so we banned cod , but we also let the seals rebound , and they were way ahead of the cod so its not helping much.. so the problem is like easter island right now , the population of seals is so big the cod cant sustain it , they will eventually be wiped out unless we even things out a bit by killing the seals and have a more clear understanding of our ecosystem and how it works
If we dont the seals will eat the cod until they are gone , then the seals will die because there arent enough cod to sustain them..
