Artist Josh Keyes recently unveiled new works that showcase graffiti plastered over things like icebergs, whales and spaceships. "Who is to say what surface is to be kept graffiti clean? My personal concern is that this will be a reality some day and speaks to a larger issue of our relationship with the natural world," says Keyes. "The satellite and space graffiti hints that even if we colonize other worlds, what mark will we leave? No matter where we go there is evidence of our presence." His messages reminds us a lot of the Crystallized Books series by Alexis Arnold. With climate control becoming increasingly evident, many artists are clearly thinking about the impact we as humans are having on planet earth. Scroll down for more and follow Josh on Instagram.
