In today’s world most people do not care about the environment. People abuse the natural resources that we were given for their own benefit. It is estimated that 60 percent of the worlds population lives within 60km of the coast and that each year more than 2 billion tons of carbon dioxide is absorbed into the ocean. Almost all of the problems with the ocean are man made. Ocean heath has deteriorated due to humans depleting fish supplies, polluting the ocean, and a general lack of knowledge about just how fragile the ocean is. Overfishing is one of the largest and most relevant problems effecting ocean health today. It is defined as “The practice of commercial and non-commercial fishing which depletes a fishery by catching so many adult…show more content…
Over the past several decades, humans have caused the health of our ocean to decline considerably. Along with climate change and ocean acidification, overfishing has destroyed many marine ecosystems. In the 1990’s, one of the worlds most abundant cod populations was quickly destroyed. The Newfoundland cod fishery had been one of the most productive cod fisheries in the world. Fishing for cod in Newfoundland had dated back to the 16th century, when the amount of fish seemed endless. The Canadians had traditionally fished sustainably for cod using small boats and traditional methods such as jigging or small inshore gill nets, but in the 1950’s and 1960’s other countries began to join in on the fishing, using larger boats and nets. England, U.S., The Soviet Union, Spain, Portugal and Germany all joined in on the action, increasing the annual catch from 250,000 tons to over 800,000 tons in 1968. From then on, the population slowly began to decline. With so many being caught each year, the fish were no longer able to reproduce as efficiently and renew their numbers to keep up with the demand. In addition to an increase in the commercial fishing fleets, new fishing technologies were created to help catch as many fish as possible. Larger nets that dragged along the bottom were created to catch every possible fish. These nets were killing young fish, other marine life, and the food source for the cod, which eventually led to the entire
