Be the Solution to Ocean Pollution

Central Idea: The quality of the ocean and health of sea life is greatly impacted by the contents that go into the sea, so the people of this world should limit the amount of litter and pollutants that potentially contribute to this problem.
I. Attention Getter: Breathe slowly. Do not hold your breath. Equalize early and often. Stay off the seafloor. These are a few of the thoughts going through my mind while descending on my first open-water dive in Monterey, California. I hear the eerie silence, interrupted only by

A motorbike dumped in the water will take 50 years just to rust away. The engine will take at least 200 years to dissolve completely (Hutchinson). The oil and petrol residues will harm animals for a very long amount of time. a. Some people may not care about these effects because they “do not have anything to do with humans”, but think about how the food chain works. Small organisms will feed on this rust and oil residue. The larger fish will feed off those small organisms. All the while, we, humans, are catching these fish and eating them. At the rate that people are catching and eating fish. Who knows how many fish have been distributed that had harmful residue on their surfaces. 3. Other debris that is more ocean-based comes from boats, specifically merchant ships. Plastic is used for a plethora of uses on a merchant ship. This includes plastic strapping bands, sheeting, and shrink-wrap, which all interfere with marine wildlife. Recreational fishing holds home to one of the deadliest forms of debris imaginable - monofilament line. This is the strong, clear, common fishing line used with common fishing poles. Fishermen often cut this when it becomes snarled or snagged on an object. It is not
