After the war, Leo Castelli opened an art gallery and discovered many artists as Jackson Pollock, Robert Rauchenberg, Roy Lichtenstein and Andry Warhol. Castelli died in 1999 but Rolando Politi was an Italian artist that still lived in New York. He was a ''trash artist'' because he took trash from the street and trasformed the trash in art.He and his friends cleared out the trash and we tried to salvage it and use for something else. In a interview he said that he didn't need a work because his life and his art were one and the same. After a long period people were very interested to recycling.They understood that if we want to save our planet we have to re-use these things.With this same concept In Argentine some people have made houses from newspapers, plastic battles and rubber tyres.
