Land mines are explosive devices placed on or just below the ground, designed to detonate when triggered by pressure, movement, or a remote signal. They are often used in military conflicts to control areas and prevent enemy movement. Land mines can remain dangerous long after a conflict has ended, posing risks to civilians and wildlife. There are two main types of land mines: anti-personnel mines, which target individuals, and anti-tank mines, designed to destroy vehicles. The use of land mines is controversial due to their long-lasting effects, leading to international efforts like the Ottawa Treaty to ban their use and promote clearance efforts.
