There are places in the world that have never been explored by humans, including the Mariana Trench, the deepest point on Earth's ocean floor, which James Cameron reached in 2012. Despite expectations of finding unknown creatures, the trench mostly contains darkness and sediment. In other regions like Greenland and Antarctica, harsh weather and extreme cold make exploration difficult. Greenland, despite being the world's largest island, is 80% covered in ice. Antarctica is even colder, with temperatures dropping to -97°C. Additionally, certain territories in Russia, like Yakutia, are sparsely populated due to their extreme conditions. Finally, there's a mountain that has never been climbed, surprising given humanity's penchant for conquering peaks."
