Subject:
We are placing unprecedented pressure on marine resources Half the world?s marine fish populations are fully exploited 25% of fish population are overexploited and heading to extinction Total fisheries catch leveled off after 1998, despite increased fishing effort populations of all ocean species we fish for today will collapse by the year 2048 People began depleting sea life centuries ago Some species hunted to extinction: Steller?s sea cow, Atlantic gray whale, Caribbean monk seal Overharvesting of Chesapeake Bay oyster beds led to the collapse of its fishery, eutrophication, and hypoxia Decreased sea turtle populations causes overgrowth of sea grass and can cause sea grass wasting disease People never imagined that groundfish could be depleted
