This report describes, quantifies and, where possible, calculates the economic value of Tonga's marine and coastal resources. Seven key marine ecosystem services are evaluated in detail: subsistence and commercial fishing; minerals and aggregate mining; tourism; coastal protection; carbon sequestration; and research, management and education. Others services are explored as well, including cultural and traditional values associated with the sea, potential future industries and other human benefits that have not yet been analysed or exploited. The scarcity of data about many of these ecosystem services prevents alculation of the total economic value, so the values below should be regarded as minimum estimates. Data gaps are described in detail in this report.

This story is about greenhouse gases. Greenhouse gases are gases that trap heal in +he atmosphere and keep our plane! Earth warm. For the last- hundred years or so, we have been releasing more and more greenhouse gases This is because we are using more fuel like petrol, diesel and oil for our machines, factories and cars and we are cuffing down more forests. These activities release greenhouse gases. As we release more greenhouse gases, our atmosphere gets warmer. This can cause a rise in sea level, long droughts and extra heavy rainfall. So it is important to know about greenhouse gases and how +o reduce +he release of them into our atmosphere.
