Tuvalu, a country comprising nine coral islands that dot the South Pacific, is known as a vulnerable country in terms of sea-level rise which is said to be caused by global warming.The damage caused by beach erosion that one of the islands is already submerged is extremely grave, however, it appears this is no longer a problem that can be resolved by Tuvalu alone.The fearful cries of small islands floating in an endless sea are Earth's own cries.
