Land mines are explosive devices designed to be placed on or just below the ground. They are often used in military conflicts to deny access to certain areas or to protect strategic locations. When triggered by pressure or a tripwire, land mines can cause significant injury or death to people and animals. These devices can remain dangerous long after a conflict has ended, posing risks to civilians and hindering post-war recovery efforts. Efforts to clear land mines involve specialized teams and technology, and organizations like the United Nations work to promote mine clearance and support affected communities.
