Marine Pollution: Centuries of Abuse Have Taken a Heavy Toll	This article is about how the man made pollutants are reaching the oceans and affecting the animals in them. It also points out that the pollution in the ocean also affects humans- since the fish we eat are ingesting pollutants, we are as well, but ingesting the fish. The pollutions don’t always start in the ocean though. Some of the pollution that ends up in the ocean is because it started in a stream by a farm, where pesticides and fertilizers got into it, and eventually flowed into the ocean. Pollution also occurs with boats dumping solids like plastic and Styrofoam into the ocean, where animals mistake it for food. Proof of this is the big “Pacific Trash Vortex” in the North Pacific- a big floating pile of trash the size of Texas in the middle of the ocean. This article also mentions noise pollution- sound waves from above water that confuse animals and mess up their natural patterns, like migration.
