The oceans of 2050: will there be any fish left?

Having reached peak fish, the resulting fish stock collapses have meant that maintaining the annual landing of 85 million tons of fish in the 2000s became more and more energy intensive. Forty-seven million tons of fuel were used by the global fishing fleet each year over that decade, which works out to 1.8 tons of fish per ton of fuel, or 13.5lb of fish per gallon. Just as global agriculture has become incredibly dependent on fossil fuels, so too has global fishing, and it’s just as unsustainable.
