According to the United Nations Environment Programme, the fish stock supply will plummet as the world heats up, impacting millions of people who depend on fishing for their livelihoods. It's a shocking piece of information, especially if you are a fisher or like to enjoy it for dinner.

Oceans have become warmer over the years. This, as part of a changing climate, is modifying fish distribution.

"More carbon dioxide in the atmosphere is making ocean water more acidic," said Mark Fischetti, an editor with Scientific American. "That affects the ability of microorganisms to thrive. Those microorganisms are the basis for the entire marine food chain."

With fish moving to new locations, this will most definitely have an impact on the future of the sport.
