"Create an impactful poster on an A3 size layout with the theme 'Ban Plastic and Save Earth.' The top half of the poster should depict a distressed Earth being choked by plastic waste, such as plastic bags, bottles, and straws, with the plastic wrapped around the globe like chains. The colors in this section should be dark and polluted, emphasizing the negative impact of plastic pollution. In contrast, the bottom half should show a vibrant, healthy Earth, free from plastic waste, symbolizing a cleaner and more sustainable future. Surround the healthy Earth with symbols of recycling, renewable energy, and flourishing ecosystems, like trees, animals, and clean water. Use bright, natural colors in this section to create a positive and hopeful atmosphere. Include the headline 'Ban Plastic, Save Our Planet!' prominently at the top, in bold, striking text. Add a subtext below the headline that reads, 'Every piece of plastic ever made still exists. Let’s choose a sustainable future.' At the bottom of the poster, include a call to action: 'Reduce. Reuse. Recycle. Say NO to single-use plastics!' Use a clean, readable font for all text elements, and ensure the overall design is visually balanced and compelling."
