The Ohio River at Cairo is 281,500 cu ft/s (7,960 m 3 /s); [1] and the Mississippi River at Thebes, Illinois, which is upstream of the confluence, is 208,200 cu ft/s (5,897 m 3 /s). [66] The Ohio River flow is greater than that of the Mississippi River, so hydrologically the Ohio River is the main stream of the river system.
Overfishing of sharks has increased as the global demand has skyrocketed in recent years. Sharks are hunted for their meat, skin, cartilage, fins, livers, and teeth.
[30] [failed verification] Sharks are an important part of the ocean ecosystem and are "an indicator for ocean health." Their role keeps the environment healthy because "they usually go after the sick, weak and slower fish populations." Due to shark overfishing in many areas in the world sharks are going missing or endangered. [31]
The IPCC (2019) says marine organisms are being affected globally by ocean warming with direct impacts on human communities, fisheries, and food production. [67] It is likely there will be a 15% decrease in the number of marine animals and a decrease of 21% to 24% in fisheries catches by the end of the 21st century because of climate change.

Porbeagle sharks are listed as vulnerable by the International Union for Conservation of Nature because they were overfished beginning in the 1960s. By around 2001, estimates suggested the species ...
[11] [13] Sharks are also killed for their flesh in Europe and elsewhere. [14] The 2007 film Sharkwater documents ways in which sharks are being hunted to extinction. [15] In 2009, the IUCN Shark Specialist Group reported on the conservation status of pelagic (open water) sharks and rays. They found that over half the pelagic sharks targeted by ...
The overfishing list reflects species that have an unsustainably high harvest rate. NOAA also keeps a list of overfished stocks. Those are species that have a total population size that is too low.
