Tuvalu is one of the smallest countries in the world. It has a population of only 11,500 and has been inhabited for almost 3,000 years. In 1997 the then Tuvalu Prime Minister Koloa Talake addressed world leaders at the Kyoto conference. He petitioned countries around the world to take immediate action on global warming and make the changes needed to stop it in its tracks. He explained his low-lying country was sinking into the Pacific Ocean because of rising sea-levels. The current Prime Minister of Tuvalu, Enele Sopoaga, said climate change was the ‘Enemy Number One’ for his country. The people of Tuvalu don't require scientists to explain it to them. They can see it for themselves. Salt water is flooding the land and the people are having difficulties growing their crops because of salination of the soil. Groundwater is increasingly becoming undrinkable due to sea-water contamination. It is brackish and salty. Islanders are relying on catching rain water.
