Mexican artist Alejandro Duran has a sobering exhibit called Washed Up that deals with plastic garbage that washes ashore onto Mexico’s largest federal protected reserve. Ocean currents move the massive amounts of waste from many different countries to the shore of Sian Ka’an, near Tulum. This gorgeous stretch of beaches and caves is marred by the trash, and Duran arranges it in a sort of Andy Goldsworthy-esque fashion to create awareness and striking art.
