How important is the ocean? Plants that grow in the ocean produce half the oxygen all of the world’s population needs to survive (The Nature Conservancy, 2014). The Carbon dioxide the body releases is also absorbed by the ocean’s waters (The Nature Conservancy, 2014). Medicine that is used to fight cancer and cure disease is formulated from ingredients from the ocean (The Nature Conservancy, 2014). Not only does the ocean keep the people of the world healthy but it accounts for 128 billion dollars of the GDP, keeping the economy healthy also (The Nature Conservancy, 2014). The ocean is a big part of what makes Earth a place where human beings can live and flourish. It is surprising that despite the oceans great importance people are still destroying it, through a series of events that starts with a simple trip to a local sushi restaurant. Eating tuna causes destruction of the ocean because of the elimination of species and it’s effects on the food chain.
Eating tuna causes demand for tuna to go up. Demand for a product is defined by Reem Heakal as “ how much (quantity) of a product or service is desired by buyers” (N.D., pgh. 1). When a person goes into a sushi restaurant and orders the blue fin tuna special the chain reaction is started. Purchasing a product is like sending a vote for the product to the company who controls the production or in regards to tuna the killing of the product. However with a product like tuna there is not an infinite supply that a company can produce because tuna are living creatures. When a person eats tuna it causes the demand for tuna to go up.
When the demand for tuna goes up more tuna have to be killed in order to satisfy the demand. Supply is the other side of the demand coin. Reem Heakal defines supply as “how much the market can offer” (N.D., pgh. 1). In order to increase the supply of tuna for restaurants and grocery stores the tuna have to be located, captured, and killed. The market has to be able to increase supply for the people who are demanding the product. Harvard International Review states in an article entitled Big Tuna that “Bluefin tuna poaching has doubled in volume since 2007” (MIN, 2010, page 9). The doubling of poaching is due to the increased demand for the product of tuna. Due to the increased demand of for tuna are killed in large numbers in order to meet demands.
When the number of tuna killed continues to rise the species are wiped out so fast they have no time to repopulate. This idea is known as overfishing (National Geographic, N.D.). Technology advancement is a big contributor to the elimination of species. For example both GPS and Sonar have made locating tuna easily accessible (Valasquez-Manoff, 2008). In the past fish could find logs or small trenches to hide in or under and escape fishermen. With sonar technology there is basically a map that leads the fishermen to whatever nook or cranny the fish could possibly hide in. When the fish continue to die there is no time for them...
