From outer space the world looks blue because of the extent that oceans cover its surface and of all the oceans the greatest is the Pacific. It stretches from the Arctic to the Antarctic, more than halfway around the globe and is twice the size of the next biggest ocean, the Atlantic. It harbours trenches 11,000m deep, which makes it the deepest of the oceans. Along its rim are some of the worlds richest nations. Huge cargo ships cross it carrying minerals, such as iron ore and copper from Australia, and manufactured goods from Japan, China and the United States. More than half the worlds catch of fish is from the Pacific. Most of the worlds palm oil is manufactured from the dried flesh of coconuts on the over 20,000 islands of the Pacific.
