Answer 1

Hook:
From beaches littered with plastic to vast oxygen‑poor "dead zones" where marine life cannot survive, ocean pollution is turning once‑vibrant seas into struggling ecosystems.

Thesis statement:
Ocean pollution—driven mainly by plastic waste, agricultural and industrial runoff, and oil and chemical spills—is severely damaging marine ecosystems, harming human health and economies, and requires coordinated policy, technology, and behavior changes to reverse.

Overview and transition into first body paragraph:
This paper will first describe the primary sources of ocean pollution (land‑based plastic and trash, nutrient and chemical runoff, and accidental or chronic oil and chemical discharges), then examine the ecological and human impacts (on biodiversity, food webs, fisheries, and public health), review notable case studies and scientific evidence (such as the Great Pacific Garbage Patch and coastal dead zones), and finally evaluate solutions and prevention strategies (improved waste management, policy measures, cleanup technologies, and individual actions). To begin, I will analyze the main sources of pollution entering the oceans—focusing on plastic waste, agricultural runoff, and industrial discharges—and how they reach marine environments.
