Slow and silent, former logging elephant Mae Khoun Nung emerges from a forest in northern Laos and follows her guide to an animal hospital for a check-up. Once abundant in the forests of Laos, Asian elephants like her have been decimated by habitat destruction, gruelling labour in the logging industry, poaching and scarce breeding opportunities.
