Portuguese street artist Bordalo Segundo aka Bordalo II has been hard at work in Lisbon. His latest piece, Our Gift To Mother Nature, employs garbage, red spray paint, and snarky wordplay. At a dumpster site in Portugal, the street artist tagged an overflowing gray bin with a large red X. While the garbage will eventually be discarded, and the paint will fade, the artist’s message is timeless and urgent. With two swoops of his talented arm, Bordalo II reappropriated human waste into an essential truth.
