Pop Art celebrated consumer culture, the next wave of artists began to question consumer culture. Television, especially, had created a distance between the viewer, the object and the representation. Some artists turned back to nature. In the 1970s, increased concern over pollution and environmental degradation began to take hold of the public consciousness. Smog-filled cities and chemical-laden rivers became public issues. Around this time environmental art emerged. In these works, artists used the land itself as a canvas. These artists took art out of the galleries and museums and placed it where people couldn't help but see it.
