Mark Schleifstein joined the Times-Picayune in 1984 as an environmental reporter after five years at the Clarion-Ledger of Jackson, Mississippi. Since 1996 he and his Times-Picayune colleague John McQuaid have written numerous major environmental series for the paper, most recently in January 2006. Schleifstein and McQuaid won the 1997 Pulitzer Prize for Public Service for their series “Oceans of Trouble: Are the World’s Fisheries Doomed?”—a comprehensive eight-day series about the threats to the world’s fish supply, including the effects of coastal wetlands erosion on fish in Louisiana and the Gulf of Mexico. In 1998 the Picayune published their series “Home Wreckers: How the Formosan Termite Is Devastating New Orleans,” a finalist for the 1999 Pulitzer.
