The article brings to light the fact that the majority of the oil pollution in the ocean does not come from major oil spills that we see on the news. There are three other causes that together make up 92% of the oil pollution in the ocean. The biggest source of oil comes from natural seepage. Oil is a natural resource, and it can leak into our water and flow into the ocean or leak directly into the ocean. Also, oil from our vehicles on land can leak and run off into water systems and flow into the ocean. And lastly, oil can leak from boats directly into the water.
