Turning to the landfill

Do you know that Staten Island's Freshkills Park was once the world's largest landfill?
When I read this article about it, it makes me realize certain common points with my artistic process.
By definition, a landfill is a place to dispose of refuse and other waste material by burying it and covering it.
When I create a new artwork on paper or canvas, I exactly follow the same steps - burying and covering forms or colors.
