NEW YORK — The world faces the nightmare possibility of fishless oceans by 2050 unless fishing fleets are slashed and stocks allowed to recover, UN experts warned Monday.
"If the various estimates we have received... come true, then we are in the situation where 40 years down the line we, effectively, are out of fish," Pavan Sukhdev, head of the UN Environment Program's green economy initiative, told journalists in New York.
Now lets be fair. Are the fish populations being harvested faster than they can reproduce? There is evidence to suggest this is true.
How much of what is caught is wasted? Spoils at market, on the way to market or while in the nets? What about the unacceptable fish that are caught and tossed overboard?
Change is not always a bad thing.
It makes sense. When there is overfishing coupled with an increasing number of dead zones in the worlds oceans the population of certain fish species is reduced beyond the rate of replenishment. When that happens a negative feedback loop occurs and unless the status quo changes it is very possible that sometime in the future fishing could no longer be commercially viable for certain types of fish.
