Can you describe the Korean demilitarized zone with 5 characteristics?

The Korean Demilitarized Zone (DMZ) is a buffer zone established between North and South Korea, characterized by its 250-kilometer length and 4-kilometer width. It is heavily fortified, featuring military installations and surveillance systems on both sides, yet paradoxically serves as a sanctuary for wildlife due to limited human activity. The DMZ is marked by a tense atmosphere, as it symbolizes the ongoing conflict and division of the Korean Peninsula since the Korean War. Additionally, it includes the Joint Security Area (JSA), where diplomatic negotiations and rare interactions between the two Koreas occur.
