โปสเตอร์รณรงค์ปัญหามลพิษพลาสติกในมหาสมุทร

A public service announcement poster addressing ocean plastic pollution. A [sea turtle] swims sadly through a dense sea of floating plastic bags, plastic bottles, and discarded trash instead of clean water. Murky, diffused underwater lighting, realistic and evocative atmosphere, poignant mood. At the bottom, clean typography reads: "[Is this the ocean you want?]". Impactful poster composition.
