Short Answer

The three methods of land disposal used in the 1970s were the landfill method, ocean dumping, and open burning. Over time, the use of these methods has changed, with landfill being engineered to control waste better and minimize environmental impact, ocean dumping largely discontinued to protect marine ecosystems, and open burning significantly diminished and regulated due to its contribution to global warming.
