The 'Microplastics' meme trend emerged as a form of nihilistic shitposting and surrealist humor on platforms like Twitter and Reddit around 2021. It satirizes the inescapable presence of synthetic particles in the human body and the global ecosystem by treating the situation with ironic enthusiasm or mock-scientific dread. Users often pair images of glowing objects, colorful beads, or chaotic characters with captions about 'crunching' on microplastics or feeling them 'take over' their bloodstream. It serves as a dark-humor coping mechanism for environmental anxiety, transforming a serious ecological issue into a recurring, absurdist internet trope that mocks the inevitability of modern pollution.
