The continent with the least population density is Antarctica. This vast and icy land is primarily covered in ice and has extreme weather conditions, making it inhospitable for permanent human settlement. While research stations do exist, they host only a small number of scientists and support staff temporarily. The average population density of Antarctica is significantly lower than any other continent, as the harsh environment limits human activities and habitation. Despite this, the continent plays a vital role in global climate regulation and is home to unique ecosystems of wildlife, including various species of seals, penguins, and seabirds.
