On any island, people need to make best use of natural resources - things from the land and sea that people need to live. We can't live without some natural resources, and others are in short supply.
I would find it impossible to live without trees, for example, but what would you need? Imagine you live on a remote island. From the list of resources, choose five that you think are absolutely necessary for your survival. Put these resources in order from the most important to the least important.
People have to make the most of the resources they have. But on many islands resources are being used up faster than they can be replaced, or they have run out altogether. Elsewhere, people are ruining their precious resources. Roll over the icons to give you an idea.
On some islands, people are losing their resources for reasons beyond their control. On Tuvalu in the South Pacific, people are losing the land itself as sea levels rise. Find out more by visiting Global Eye Summer 2002.
Water is perhaps the most precious resource of all, and the people of Bali, an island in Indonesia, have learned how to use their water resources wisely so that they last. Click on the picture to find out more.
Sand is an important resource for most tourist islands. On Sentosa island next to Singapore, they have shipped over tons of sand from Hawaii to make a beautiful beach!
Resources are even more precious when an island is a long way from anywhere else. Go to the next page to find out about some of the world's remotest islands.
