conservation issues and environmental threats

By Dr J Floor Anthoni (1997 - )
Here is the index to environmental issues and global problems as these affect the sea and the world at large. As people become more numerous and more well to do, they occupy more space while also using and wasting more of the world's resources. It is important to understand how all this is affecting the environment and how rapidly our environmental problems are increasing. In the end, we all need to change our ways and do what we can to save our environment. Read these extensive sections so you know what you can do now, and what we need to do in the near future. Better be prepared than surprised. Study how soil works, why soil is lost and how to combat erosion. Understand why beaches erode, everywhere in the world. Learn why the sea degrades and what to do about it. What are the principles of conservation and how can we save the sea? Are marine reserves working to save biodiversity?
climate change
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)
ocean acidification
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)
ozone holes
Not long ago scientists discovered an ozone hole in the atmosphere above Antarctica. It immediately became a problem. What is the story, the science and the doubt?
El Niño
At regular intervals, the climate around the Pacific Ocean changes, and fisheries collapse. It is called El Niño, and its cycle ENSO. But there is also the Decadal Pacific Oscillation PDO. What's going on and what is the science?
soil  and erosion
How soil is formed, its fertility, how we need it and farm it. How fertility is achieved and retained. How we are losing soil and what can be done. It is a must-read for all. Saving the sea begins with saving the soil. (120 pages)
disappearing beaches
Very slowly, over periods of a life time or longer, beaches around us are disappearing or becoming seriously 'ill'. Beaches seem to dislike people because many human activities make them worse. Recent observations explain what causes them to disappear. A controversial and thought-provoking issue! (50 pages)
marine degradation
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!)
poisonous plankton
Harmful Algal Blooms (HABs), new threat for the world's shores. (later)
How industry pollutes. Its effects on the sea. (later)
ballast water
The threat of ballast water. What can be done? (later)
habitat destruction
Mankind has changed his environment considerably. How much did he change the sea? (later)
History, theory, ecology, statistics, policies, fishing methods, (in prep)
The history of whaling and New Zealand's role. The International Whaling Commission. Fate and recovery of the great whales. (later)
A complete study of methods, policies and principles of conservation in general and marine conservation in particular. Includes principles of conservation, resource management, biodiversity, marine conservation, marine mammals protection, legislation, lessons, marine reserve design, monitoring, frequently asked questions, myths and more. (large, 300 pages)
war for marine reserves
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. Marine reserves no longer work to save our seas and smarter solutions are needed but government departments have taken a path of propaganda, misinformation and confrontation to do more of the same. A must-read for all as the problem is not confined to New Zealand. (large, 172 pages) plus myths and fallacies (130 pages)
marine reserves
Details of all marine reserves of New Zealand. Kermadec Islands, Goat Island, (in progress, 170 pages)
