This is an aerial documentary photograph taken at a large refuse dump in Mexico City, Mexico. The ground is almost completely covered by dense piles of various domestic waste and industrial debris. Several scavengers wearing wide-brimmed straw hats are searching for recyclable materials in the mountain of garbage. The strong light and shadow contrast highlights the vastness and mess of the landfill. The work intuitively shows the realistic dilemma of urban waste disposal, focuses on environmental pollution issues, and has strong social warning significance.
