特朗普为何盯上格陵兰？战略要地之外，这座冰封岛屿埋着“关键资源”

Core Viewpoint - Greenland has become a focal point in geopolitical discussions due to its strategic location and rich mineral resources, particularly rare earth elements, despite challenges in economic viability for extraction [2][3][4]. Group 1: Geopolitical Importance - The U.S. has shown interest in Greenland since the 19th century, with discussions about its acquisition resurfacing under the Trump administration, emphasizing national security [3]. - Greenland's strategic position lies between the U.S., Europe, and Russia, making it a significant military asset [3]. - The melting Arctic ice due to climate change may enhance Greenland's shipping potential, further increasing its geopolitical relevance [3]. Group 2: Mineral Resources - Greenland possesses the 8th largest rare earth reserves globally, estimated at approximately 1.5 million tons, with potential reserves possibly reaching 36.1 million tons, which could position it as the second-largest rare earth holder [4][5]. - The island is rich in 29 out of 38 minerals classified as critical by the EU, including nickel, copper, lithium, and various rare earth elements essential for modern technologies [5][6]. - Heavy rare earth elements, crucial for wind turbines, electric vehicles, and defense systems, are found in unusually high concentrations in Greenland [4][6]. Group 3: Economic Viability Challenges - Despite significant theoretical reserves, the actual economic feasibility of mining in Greenland is questionable due to high extraction costs and challenging geographical conditions, with over 80% of the island covered in ice [7][8]. - Current prices and production costs render the extraction of Greenland's resources economically unviable, necessitating a rise in commodity prices for feasible mining operations [7][8]. - The situation in Greenland mirrors that of Venezuela, where vast resources exist but are not economically extractable, highlighting the importance of economic feasibility in resource-rich regions [8].
