Australian media is not keeping you up to date about ocean AND waterway dead zones.
You seem to think dead zones are a thing of the past. They are not. They are worsening.

Published articles usually fail to mention government dumped sewage nutrient, usually it’s only runoff mentioned. Yet it is the total nutrient loading that proliferates excessive algae that causes the damage.

Photosynthesis-linked warmth in ocean algae was not assessed in AGW, IPCC, and Kyoto associated science. Yet plant matter has insulation and warmth retaining properties, including water saturated algae plant matter, feel a mat of algae on top of a pond on a sunny day.

I reiterate, the problem is not overfishing, the problem is nutrient pollution destroying food-web nurseries. I see it happening and have done since 1982.

Science lacks scientific evidence where tuna eat and what they eat and how much they need to eat to be content to breed successfully. True – false?
Is everything ok out there?
Is algae definitely not the problem?
“stocks of all four main species have fallen to historically low levels.”

There is hardly any tertiary stage sewage treatment locally and worldwide, the absolute majority is secondary stage only.
Unmanaged nutrient is pouring into oceans every day. Proper treatment and developing world sanitation is needed.

Solutions could include new railways, especially to transport human food/body waste nutrient back out to agriculture and farmers. Recycle, generate new productivity, business, employment, turnover, revenue. Use it for cotton. Chinese have used it for vegetables for hundreds of years. The Hanging Gardens of Babylon were fed with it, animal or human manure all same.

Capital and transport is needed and so is infrastructure to rehabilitate waterways and whole oceans.
Rail brings food nutrient from farms to people, rail can take concentrated nutrient back.
Reduce the loading.
Why not?

A conventional west-of-the-divide rail line could meander almost level or slightly downhill along and around contours of mountains.
The route could include an aqueduct that would help make the rail and aqueduct viable and achievable.
Is there any evidence this is impossible?

Adian: Where did you get the idea that any water travels under the sea from Papua to mainland Queensland?
