Bottom line in this business is that mankind is overfishing and has managed to wipe out to a high extent some rich fishing grounds.
Keep it going this way :
"dont sweat it fellas, some day you will all be dead and this subject really wont matter."
And seafood will only be for the richies...
I don't think we could "wipe out" the fish from the oceans like that but it's going to be one fine day, if we carry on like this, where the hard earned catch is just too little and expensive.
By then, many of us won't be dead.
And to be responsible, our grandchildren will be young.
