Plastic's Ocean Journey Environmental Pollution Illustration

Build visual tension around plastic's ocean journey. A visual story traces plastic from city drain to river, coast, open ocean, wildlife impact, cleanup, and prevention. Use a cohesive illustration language, confident shape design, controlled texture, clear storytelling, and a polished editorial finish. Creative treatment: Use clear systems illustration with factual sequence and constructive solutions. Illumination and color: Ocean blue, orange, gray, green, and white. For a spacious horizontal layout, begin the city on the left, move through the ocean, and finish with prevention actions on the right. Keep perspective, characters, objects, and story logic consistent； avoid copied characters, accidental text, and overcrowding.
