Sweet Sin (Süße Sünde), created by Wes21 and Onur for the One Wall Project curated by Urban Nation in 2015, stands as a powerful visual commentary on environmental issues. This mural presents a hyper-detailed apple that also resembles planet Earth, evoking the Biblical reference to the forbidden fruit in the Garden of Eden. The partially eaten apple symbolizes humanity's "sweet sin" of temptation, exploitation, and disregard for nature’s limits.

The mural reveals outlines of continents on the apple’s surface, subtly integrating Earth's geography into the fruit’s form. As the apple decays and fragments peel away, it serves as a reminder of our planet’s vulnerability under human influence. This visual metaphor encourages viewers to consider the “parasitic” impact of human behavior on the environment, suggesting that our ongoing consumption is steadily destroying the ecosystem. By transforming an ordinary wall into a striking environmental statement, Süße Sünde invites reflection on the urgent need for more sustainable and respectful treatment of our shared world.
