Landfills- A Growing Menace
When asked to think of the largest man made structure, people will invariably

It sports an elevation of 155 feet, an estimated mass of 100 million tons, and a volume of 2.9 billion cubic feet. In total acreage, it is equal to 16,000 baseball diamonds [Miller 526]. By the year 2005, when the landfill is projected to close, its elevation will reach 505 feet above sea level, making it the highest point along the Eastern Seaboard, from Florida to Maine. At that height, the mound will constitute a hazard to air traffic at Newark airport [Rathje 3-4]. The area now encompassed by the Fresh Kills (Kills is from the Dutch word for creek) Landfill was originally a tidal marsh.
