People and tigers in a Himalayan valley are walking the same paths, albeit at different times of the day.

    Since the start of the 20th Century, the world’s population of wild tigers has dropped by 97% from an estimated 100,000 to approximately 3,000 individuals. The world’s remaining tigers are being pushed into small spaces, and being able to share that space with humans is a critical survival skill.

    The tigers here appear to have found a middle ground that keeps their population viable.
