The Wall Street Journal reports on the state of Fresh Kills Landfill, a site that had been one of the largest landfills in the world for the last half of the 20th century. Today, the closed site is being converted into a 2200-acre park, which will make it three times larger than New York’s Central Park. Over the next 30 years, while methane wells continue their post-closure work, the site will be transformed with hiking, biking and horse-riding trails; public spaces; kayaking zones; and more.
