A study was published that says there will be a global seafood collapse by 2048.
I think this is going to be the one that actually comes true. The global fishing economy is too huge and impacts too many people for there to be a global consensus on fish conservation.
The article says:
"Joshua Reichert, head of the private Pew Charitable Trusts' environment program, pointed out that worldwide fishing provides $80 billion in revenue and 200 million people depend on it for their livelihoods. For more than 1 billion people, many of whom are poor, fish is their main source of protein, he said."
In a six billion person world that is about 16% of the globe that depends on fish for its main source of protein.
What are the repercussions of a global seafood collapse. Mass starvation in third world coastal communities? An explosion in thirdworld brith defects and still birth as protein deficient mothers are unable to produce healthy babies? I don't know if either one of those things are true, but they easily could be.
