The Pacific Ocean is the largest single geographic feature on our planet. It represents half the world’s ocean area, occupies one-third of the earth’s surface, and helps support complex ecosystems, ocean-based economies, and hundreds of millions of people.
That is directly quoted from the Center for Ocean Solutions which is affiliated to Stanford University:
The Pacific is also the engine room of Earth’s climate and the storeroom of its ocean biodiversity.
However, the people from around the Pacific Ocean, from the Arctic to Antarctic, from countries populous and sparse, are witnessing a decline of the Pacific Ocean’s vast resources and in the ability to use those resources. Pollution, habitat destruction, overfishing, climate change, and invasive species emerge repeatedly as the major causes. These threats interact with each other to damage natural ecosystems, reduce biological and human economic diversity, destroy productivity, and encumber human use of the sea.

It identifies the following threats to the Pacific Ocean:
We hope others, in and outside of the South Pacific region, will take up the challenge and write about these threats to our environment and survival, particularly for small island nations. Due to scarce resources and available time, we aren’t able to do justice in covering these stories . Wish we could. For example, do people, other than governments and environmental groups, in the Pacific region realise the impact of overfishing for the region? I think not. What role have island governments played in protecting those assets? Can they? This is a big business story, not just a marine story. Who are the biggest contributors to the depletion of these natural marine resources? And what role is international legislation doing, or not doing, to protect the vast resources of the Pacific Ocean.
To give us a perspective of sizes, look at a map of the oceans of the world. The smallest is the Arctic Ocean, followed by the Indian Ocean, then the North and South Atlantic Ocean. Then there’s the North and South Pacific Ocean. Yes, it is the largest biggest ocean out there. It covers a wider geographical area bigger than all the other oceans combined.
American Samoa radio broadcaster Joey Cummings captures the incoming surge from the second story of Pago Plaza in Pago Harbor. He describes the disaster as it unfolds. You can hear the fear in his voice as he speaks.
