A periscope can improve people's lives by allowing them to see over obstacles or around corners, providing a better view of their surroundings in situations where direct line of sight is limited. This can enhance safety, security, and efficiency in various applications, such as military operations, search and rescue missions, or even recreational activities like birdwatching.
