Stars of the show they may be, but elephants, lions and tigers are the wild animals least suited to life in a circus, concludes the first global study of animal welfare in circuses.
"It's no one single factor," says Stephen Harris of the University of Bristol, UK, and lead researcher of the study. "Whether it's lack of space and exercise, or lack of social contact, all factors combined show it's a poor quality of life compared with the wild," he says.
