For a long time, queer phenomena in nature have been overlooked. This heteronormative bias toward nature has, in turn, reinforced the division between heterosexuality and queerness within human society. Queer Arcadia challenges such binary patterns as human versus nature and heterosexuality versus queerness. Through a series of design practices, I aim to construct a world where queer plants, animals, and humans coexist harmoniously, envisioning a diverse future.
