　　The Threat to Kiribati

　　The people of Kiribati are afraid that one day in the not-too-distant future, their country will disappear from the face of the earth - literally. Several times this year, the Pacific island nation has been flooded by a sudden high tide. These tides, which swept across the island and destroyed houses, came when there was neither wind nor rain. This never happened before, say the older citizens of Kiribati.

　　If the trend continues, scientists say, many countries will suffer. Bangladesh, for example, might lose one-fifth of its land. The coral island nations of the Pacific, like Kiribati and the Marshall Islands, however, would face an even worse fate - they would be swallowed by the sea. The loss of these coral islands would be everyones loss. Coral formations are home to more species than any other place on earth.

　　16 The people of Kiribati worry that one day their country will be taken away by a sudden high tide.
