The Impact t of Overfishing on the extinction of ubiquitous species of tuna

The National Geographic article “Overfishing: Plenty of Fish in the Sea? Not Always” provides useful information regarding the negative impacts of the Ocean overfishing. In particular, the article affirms concerns about the risk of extinction of some of the ubiquitous species of tuna as a result of the high demands on the Japanese sushi in global market.  The article traces back the earliest attempts of overfishing to the 1800s when humans decimated the whale population.  By the mid-1900s, some fish that we eat, including Atlantic cod and herring and California's sardines, were also harvested to the brink of extinction.  According to the article a scientific report in 2003 estimated that industrial fishing had reduced the number of large ocean fish to just 10 percent of their pre-industrial population.  The article cites some studies that alarm against the impact of overfishing on the lives on the ocean. A study of catch data published in 2006 in the journal Science grimly predicted that if fishing rates continue apace, all the world's fisheries will have collapsed by the year 2048.
