text: The triangle of death () is an area approximately 25 km northeast of the city of Naples in the Province of Naples, Campania, Italy, that comprises the comuni of Acerra, Nola and Marigliano. This area contains the largest illegal waste dump in Europe due to a waste management crisis in the 1990s and 2000s. 
  The region has experienced a rise in cancer-related mortality that is linked to exposure of pollution from the illegal waste disposal by the Camorra criminal organization after regional landfills had been filled to capacity.
  The phenomenon of widespread environmental crime perpetrated by criminal syndicates like the Camorra and 'Ndrangheta has given rise to the term "ecomafia".
