In 2013 John Tanacredi, an environmental sciences professor at Molloy College on Long Island, N.Y., received a call from a friend who worked at nearby John F. Kennedy International Airport. “You’ve got to see this,” he told Tanacredi, and sent him a photo of a cargo container filled with 600 dead horseshoe crabs. It was mid-July, and airport officials had opened the container because of a rotting stench.
