This poster challenges the belief that glass is more environmentally friendly than plastic by revealing its hidden costs. The design uses chimneys, smoke, and shattered glass to symbolize pollution and industrial damage, contrasting with the common image of glass as “clean” and “sustainable.” It highlights a striking fact: producing one glass bottle can be as harmful as making four plastic bottles. Glass manufacturing requires vast raw materials and high energy, releasing around 86 million tons of greenhouse gases annually. By exposing this overlooked impact, the poster encourages viewers to rethink assumptions and make more informed, sustainable choices.
