| The world's climates are changing, thought to be related to global warming. The world appears to be warming because of human emissions, is the consensus, but many scientists disagree. This large chapter views all issues from a wide perspective, to foster understanding. (140 pages) | ||
| Oceans can absorb large amounts of CO2 but in doing so, can become more acidic. How serious is this and should we be alarmed? What do we know for sure? (50 pages) | ||

Recent observations explain what causes them to disappear. A controversial and thought-provoking issue! (50 pages) | ||
| The new and rapidly increasing threat of marine degradation caused by land-based pollution is explained step by step. This is perhaps the most important chapter on this web site as it chronicles the answers to the simple question why are we losing so much so fast? A must-read for all, since degradation has become the foremost threat in the sea, eclipsing that of fishing. This chapter contains new science from own observations. (a large and growing section, must-read!) | ||

| The war for marine reserves. The NZ government is waging a war against its own people for more and larger marine reserves, even though those in existence are degrading from bad to worse.
