Why Farming Fish Is More Unsustainable Than Catching Them In The Wild

Arthur T Knackerbracket has processed the following story:

It has been claimed that fish farming is a sustainable source of food that will help us feed the growing global human population while protecting wild fish populations – but this isn’t true.

“Fish farming is not a substitute for catching wild fish out of the ocean,” says Matthew Hayek at New York University. “In fact, it relies on catching wild fish out of the ocean.”

Hayek and his colleagues have shown that the amount of wild fish killed in order to feed farmed fish is between 27 and 307 per cent higher than previous estimates.

Farmed carnivorous fish eat multiple times more weight in wild fish caught from the ocean than is obtained by farming them, says Hayek. For instance, producing a kilogram of salmon may require 4 or 5 kilograms of wild fish.

  Also: +80 million per year (average) over a span of 60 years = +4.8 billion, for a net close to 13 billion, or 60% more people in those 60 years, and to keep these birth rate trends "down" as low as we are, we have been increasing resource consumption per person steadily.

  I was born in the 1960s, from that perspective 8 billion - 60%, or 3.2 billion total, seems like a much more rational number for total human population.

  The Georgia Guidestones suggested a limit of 0.5 billion, and that got them blown up by Anonymous Cowards in the night.

  We don't have a reason to care what number the creator of that monument pulled out of their ass(es).

  Credibility doesn't come from having crazy enemies.
  
  The problem with inventing numbers about what the population of Earth should be, is that they ignore reality. There are over 8 billion people on Earth, and they aren't going away in the short term. My take remains that the best we can do for them is to create a global developed world civilization. That's probably the only way we will see 3.2 billion people again on Earth absent a die-off.
