when I was a kid, (in the 40s & 50s),we heard that we would one day "feed mankind from the inexhaustable seas"...now the Grand Banks are depleted, the salmon are threatened, there are limits on crabs & rockfish in Cheasapeake Bay, the whales are in danger...etc...etc...

The math is plain...you CANNOT take so much fish, lobsters, etc that they cannot be replaced. (You can't pollute so much, either.) In one generation of fishing, we have gone from seemingly plenty to not nearly enough. The immediate effect is rising prices, so that good seafood, once almost free for the taking, is a rare treat, unless you are well-to-do. The next effect is shortages and bans and panic, (both ecological & financial).

The ONLY real long term solution is fewer people, If there were only 1 billion people in the world, we could all have plenty to eat....fish, or grain or red meat...at 6 billion, we are hurting...at 12-15 billion it ain't gonna be ANY fun!

Some folks keep expecting technology, fish farms & vitamins to 'solve' it, but if I were you, I wouldn't hold my breath. "X" number of hungry mouths need "Y" lbs. of food...and the Earth has "Z" amount of resources.

No one wants to look directly at the solution, because it is counter to the way we have lived for countless generations...children & growth. This is both a cultural & economic problem....but it won't go away by denying it.
