The main reason why Valu moved to New Zealand is

The meteorological department of Tuvalu, a Pacific island country, issued an early warning on February 16, saying that there will be a special tide this week, and Tuvalu is likely to be swallowed up by seawater. Tuvalu, with a total area of only 26 square kilometers and a total population of about 1. 1 0,000, has a tropical maritime climate. Since the nine small islands in Tuvalu are all below 4.5 meters above sea level, in recent years, Tuvalu is in danger of being swallowed up by seawater at any time with the increase of the earth's temperature. Tuvalu Meteorological Department predicted on Thursday (1February 9) and Friday (February 20) that the wave on 19 would reach 3.07m; It will reach 3. 1 m on the 20th. Wawa warned that seawater may flood into the home of Funafuti, the capital, and even the airport, including her office. As early as 200 1, the Tuvalu government stated in a statement that their efforts to fight sea level rise had failed and they would give up their homes and emigrate to New Zealand. Tuvalu will thus become the first country in the world to relocate all its population due to sea level rise. Some experts also predict that in about 50 years, this beautiful island country will sink into the ocean, and people will never find its position on the world map. In the past 100 years, the global sea level has risen by 18 cm. At present, scientific research institutions all over the world believe that the earth has entered a "double rising period" of sea level.

It is reported that Kiribati, Cook Islands, Nauru, Western Samoa and other low-lying island countries are also facing the same threat as Tuvalu.
