Oceans Tuna

Role in Oil: This according to Manning Green eaters, especially vegetarians, advocate eating low on the food chain, a simple matter of energy flow. Eating a carrot gives the diner all that carrot’s energy, but feeding carrots to a chicken, then eating the chicken, reduces the energy by a factor of ten (Manning, 2004).  The chicken wastes some energy, stores some as feathers, bones, and other in edibles, and uses most of it just to live long enough to be eaten. As a rough rule of thumb, that factor of ten applies to each level up the food chain, which is why some fish, such as tuna, can be a horror in all of this (Manning, 2004). Tuna is a secondary predator, meaning it not only doesn’t eat plants but eats other fish that themselves eat other fish, adding a zero to the multiplier each notch up, easily a hundred times, more like a thousand times less efficient than eating a plant (Manning, 2004).

It must also be recognized the large boats that are used to catch and transport the tuna back to land. Once the tuna has arrived on land , it undergoes processing in order to obtain its light flaky texture.

Delivery: Trucks from Richmond British Columbia are used to transport the tuna cans to retail stores, however, Ocean`s distributes its products all around the world.

Richmond BC to Vancouver BC- 14km. aprox.

Packaging: Apparently there is a new type of tin metal that can be 100% recycled, if this is the case, using tin may become somewhat sustainable. Tin is not actually used in the production of tin cans, a form of aluminum is used and only 65 % of the product can be recycled. I am unsure as to what material Ocean Fisheries uses, I have a hunch it is aluminum.
