Humans can not be the only thing that is hurting the Earth. When you really think about it, Earth goes through a lot of natural disasters, which cannot be controlled. According to an activist, Tim Haering, “Tsunamis, floods, volcanoes, earthquakes, tornadoes, wildfires, disease nature kills more than we kill each other.” Earth throws in all of these natural ...
Why? Our oceans cover nearly three fourths of the surface of our earth. According to overfishing.org, eighty percent of all life on earth is in the ocean, and us humans are threatening and driving them to extinction by overfishing. What is overfishing? Overfishing is defined as “To fish (a body of water) to such a degree as to upset the ecological balance or cause depletion of living creatures.” (Merriam Webster Dictionary) Recent studies from the Environmental Defense Fund reveal a bleak truth: Overfishing is depleting our oceans of sea life around the world. 87% of the world’s assessed fish stocks are at their breaking point, classified as overexploited or fully exploited. 1 out of 2 fish stocks in the U.S. are either overfished or at risk of being overfished. Moreover, 100 million sharks are killed each year. Carl Safina, world-renowned author of books such as Song for the Blue Ocean, once said, “If you're overfishing at the top of the food chain, and acidifying the ocean at the bottom, you're creating a squeeze that could conceivably collapse the whole system.” Overfishing is classified as the most dangerous threat our oceans are facing today. Worldwide, about 90% of fish stocks are gone forever. In 1990 our oceans contained at least six times more fish than they do today. Collapsing fish stocks create large ecological dead zones in our
In addition to The Shadows of Consumption, the article Dying of Consumption drops another boom about resource depletion from the ocean due to human activities. The author presented analysis which showed that 7,800 species of wild seafood out of which a 14-percent team found wide-catches of 29 percent of these species are now at least 90 percent below average (Dauvergne, 2008). If no measures are put in place to curtail this harvest, there might be a “collapse”, the team predicts. The article presents supporting evidence from a 10-year survey of the global oceans, which found over 90 percent decline of large predatory fish over the last half century. These predatory fish include cod, flounder, marlin, swordfish, and tuna. Again the author warns
There are many impacts that fishing and land animal farming have on the ocean, which are detrimental to ocean ecosystems as well as many other aspects of the environment. Overfishing, killing fish at a much quicker rate than the fish can repopulate, is one major problem. Three-fourths of the world’s fisheries are either fully exploited, overexploited, or depleted (Cowspiracy). Researchers have estimated an end of all viable fisheries by 2018 if the current trends of fishing continue (Mason). According to the Monterey Bay Seafood Watch, hundreds of thousands of animals die every year as bycatch, with one of the worst offenders being shrimp fisheries, catching up to six pounds of bycatch per pound of shrimp. Endangered species are also caught, including predators which are important in keeping the balance in ocean ecosystems (Smith). While many organizations such as the Monterey Bay Aquarium Seafood Watch recommend consumers to eat more “sustainable” fish, this will not stop the massive environmental impacts. Sustainable fishing for one does not account for the natural flux in the population of species of fish; what is considered a sustainable amount of fish to harvest one year may deplete the fishery in another year (Smith). Sustainable fish also are becoming even less sustainable as companies that label sustainable fish must find more For example, after Wal-Mart pledged to selling Marine Stewardship
Oceans, the beautiful blue gems of our world, full of bountiful resources. Well, used to be before humans slowly over fished several fish and shellfish species. Over fishing like this causes many problems from ecological issues to social issues.
Ocean fishes have been consumed by humans beyond their maximum sustainable yields for years and the Atlantic cod and squid are two examples. Cods were primarily overfished to commercial extinction. Other variables were also examined to see if they contribute to the declining population. Water temperature was the natural phenomenon that may be responsible for poor egg hatching. Human causes such as increased UV radiation from depleted ozone and bottom trawling disturbance were considered. Trawling disturbance had the worst effect while the other factors were questionable. As the cod vanished, the commercial fisher turned to squid to continue their way of life. Government policy and economics had a great deal to do with the continuing overfishing pattern of wiping out one species and then turn to another. In the end, there is no real solution which accommodates both ecology and unchanged societal uses at the same time.
This big push for more and more affordable fish has by now risked our world’s fish population. A few examples: by the mid-1900s, Atlantic cod, herring, and California’s sardines were harvested to the brink of extinction. Demand for shark fin soup in Asia has contributed to serious overfishing. Sharks, along with Bluefin tuna and many other ocean fish species, are critically endangered.
It is widely accepted that humans have been a major cause of environmental problems since we began creating our cities and especially since the Industrial Revolution of the 20th century. All aspects of the Earth have been affected by humans' desire to conquer and dominate the planet. Our impact has gone beyond pollution to altering the functioning of many natural systems. These systems include our atmosphere, several land ecosystems and the complex water environments of which we get our drinking water and food sources. The effects have been universal ranging from ourselves to just every other living organism on this planet. Sure, it sounds like we have ruined everything and probably the best this to do is just prepare for the worst of the consequences, but there is a possibility for improvement if we start correcting things now.
Overfishing is the most major problem related to oceans, but it is also the most overlooked. Fishing has been going on for thousands of years, and fish have always been seen as a renewable resource, that would replenish itself forever for our benefit. But around the world there is evidence that fish are not recove...
Rupert Murray’s The End of the Line focuses on the depletion of the oceans fisheries and the devastating effects it has already begun to have on ecosystems and less affluent populations. The film opens with a description of the tribulations of Newfoundland. Once possessing waters so populous with cod that one could “walk across their backs in the water,” improved technology and larger fishing vessels began to deplete the fish stocks. Despite placing a moratorium on fishing in 1992, the fisheries had already been depleted to the point of complete collapse. Similar processes are occurring around the world, as only .6% of the ocean is restricted to fishing vessels. According to the film, much of the ocean’s catch has declined by 90%; the continuation of current trends if continue, stocks will collapse by 2048.
