A new geological study has shown that many low-lying Pacific islands are growing, not sinking. <br/><br/>The islands of Tuvalu, Kiribati and the Federated States of Micronesia are among those which have grown, because of coral debris and sediment. <br/><br/>The study, published in the magazine the New Scientist, predicts that the islands will still be there in 100 years' time. <br/><br/>In recent times, the inhabitants of many low-lying Pacific islands have come to fear their homelands being wiped off the map because of rising sea levels. But this study of 27 islands over the last 60 years suggests that most have remained stable, while some have actually grown.
