冲上热搜！全球首个国家“举国申请海外签证”

Core Viewpoint - The unconventional measure of Tuvalu applying for migration visas highlights the vulnerability of humanity in the face of climate change, as evidenced by the lottery system determining the fate of its citizens [1]. Group 1: Migration and Climate Change - A total of 2,474 family groups, comprising 8,750 Tuvaluan citizens, applied for the "climate migration" lottery, with only 280 individuals set to receive permanent residency in Australia [1][2]. - Tuvalu's population is estimated to be between 9,500 and 11,000, making the participation in the lottery a significant national event [2]. Group 2: Environmental Challenges - Tuvalu, consisting of nine circular coral islands, has a total land area of only 26 square kilometers, with the highest point being 4.6 meters above sea level and an average elevation of just 2 meters [5]. - NASA's report indicates that the sea level around Tuvalu has risen by 0.15 meters over the past 30 years, with projections suggesting an additional rise of 20 centimeters or more by 2050, and potentially 0.5 to 1 meter by the end of the century [5]. Group 3: International Agreements - In response to the rising sea levels, Tuvalu and Australia signed the "Fale Apili Alliance Treaty" at the end of 2023, which provides annual permanent residency for 280 Tuvaluans along with various benefits such as education subsidies and health insurance [6]. Group 4: Digital Initiatives - Tuvalu announced a plan to migrate its national identity into the metaverse, aiming to create a digital twin of the nation to preserve its history, geography, and culture [9]. - The government seeks to establish blockchain-based digital passports to maintain governance and record vital events, despite internal controversies and uncertainties regarding international recognition [10].
