НУЛЕВОЙ ПЛАСТИК — Кампания по повышению осведомленности об океане

Design an award-winning environmental awareness advertising poster for a global ocean conservation campaign. The artwork should follow the visual style of premium NGO campaigns and Behance-featured graphic design projects. The composition should be split diagonally. The upper section showcases a vibrant turquoise ocean with crystal-clear water, colorful coral reefs, tropical fish, dolphins, and a majestic sea turtle swimming peacefully. The lower section transforms into a dark underwater landfill filled with discarded plastic bottles, bags, fishing nets, and waste, gradually blending into the healthy ecosystem above. A dramatic transition should emphasize the impact of pollution while keeping the overall design visually elegant rather than disturbing. Use cinematic underwater lighting with volumetric sun rays piercing through the surface. Add premium blue and teal gradients, subtle bubbles, floating particles, and realistic water refractions. Reserve approximately 25% of the upper area and 15% of the lower area as clean typography-safe space without generating any text. The composition should resemble a premium social network campaign, billboard advertisement, or Earth Day awareness poster.
