The document discusses the serious problem of pollution in the world's oceans from human activity. Vast areas of ocean are now considered "dead zones" with little plant and animal life. If the problem continues unchecked, it could have major consequences for ocean ecosystems and disrupt their ability to be a sustainable food source. Potential solutions are explored, but any solutions chosen would need to consider unintended consequences and be supported by research into their feasibility and impacts. The document provides resources for further research and outlines steps for defining the problem, identifying solutions, and making an evidence-based argument to address the issue of dying oceans.
