Mr Opinionated,

Ah, don't you enjoy the naivete of the very young ?

JF Aus is raising an extremely important issue - in my view, one even more important than climate change: how to process our mountains of waste instead of letting it flow out to sea. I don't think he/she is paranoid at all.

In developing countries, the infrastructure for rubbish disposal, sewage disposal, etc. has fallen way behind the capacity and finances of many countries to handle the problem. In many countries, both rubbish and sewage is simply dumped in the rivers and out to sea it goes. With urban growth in many developing countries being very rapid, any effective treatment program would be prohibitively costly and mean the destruction of large areas of city dwellings.

And any infrastructural projects would have to compete for scarce funding with transport corridors, airports, new power-lines, schools, etc., all of which require the destruction of housing.

So the dumping into rivers continues.

Hi Mr Opinion,

Amazing we meet here online.
Since finishing production of a film in 1982 I have been researching the cause of malnutrition among island fishermen. That long term research has led to understanding cause of world fish depletion and the social and economic consequences and possible solutions. So it is a great pleasure to meet you with your experience in environment sociology, especially because it is the islander malnutrition that is driving me with this ocean damage heard and reversed.

Briefly, I have often sat on a small ledge on top of the GBR at low tide and dangled my feet in a puddle of very warm water trapped in a hole. The warmth is a real pleasure after a long dive with cameras that have to be kept still. The lack of exertion can make my feet cold.
I have observed heat in the puddles is from direct sunlight at low tide, and that heat does not kill or damage the coral in or around the hole, or on the reef top. Therefore I think heat is not the cause of coral dying and bleaching as MSM reports.

Based on evidence I think most bleaching occurs due to nutrient pollution feeding algae that sometimes blooms. Evidence of substance indicates algae blooms sometimes inundate water surrounding coral, causing hypoxia, depriving the coral zooxanthellae algae and coral animal of oxygen.
The result is dead or damaged coral then resulting in bleaching. Evidence indicates it can be a big bloom or a small one.

I will not get egg on my face by talking non-sense so I choose my words carefully saying this.

I have a case of evidence indicating beyond reasonable doubt that algae is also warming areas of ocean, and evidence indicates example of how, where, why, impact, consequences and likely solutions.
It was about 2009 when I first wrote of algae being the cause, outlined in a published letter to an editor.
However at present the CO2 lobby and MSM want to hear nothing except about CO2. Makes me think of the flat earth society.

Cheers.

Dear JF Aus.

Very interesting stuff. What do you think of what happened at Menindee when all of those fish were killed in the Darling? I assume you would concur that eutrophication from irrigated farms using nitrate fertilisers produced algal blooms which in turn starved the fish of oxygen. A result of poor flows sufficient to prevent the growth of algal blooms. All because certain agribusinesses were siphoning off water for large scale irrigation projects particularly cotton.

Hi Joe,

Sewage wastewater does not usually go out to sea, for example hardly ever along the east coast of Australia. The dissolved nutrient is bonded to the freshwater that tends to the surface where it is pushed by prevailing winds back against the coastline, where the northerly flowing longshore current energy is located.

As for funding infrastructure and economies to achieve solutions:

1. The ocean is not presently being managed but urgently needs to be. Sewage nutrient is not measured or managed.

2. All nations are involved via waterways and/or coastlines and the predominant supply of world oxygen that comes from the ocean.

3. No nation can afford to fund ocean management.

4. There is a strong case of unequivocal evidence of international need for new ocean management resources that will also stimulate all existing economies, such as via participation of the IMF to provide existing governments worldwide with adequate resources to carry out such management.
This is about managing the life support ecosystems of this whole planet, the ocean and its waterways, which are indeed in very very big trouble (as Mr Opinion also states).

5. The plumbing industry already exists. New sanitation and updated modern sewage treatment, involves plumbing of course.

6. Nothing sensible is impossible.

But mainstream media editors apparently think they know everything. Especially news editors at our ABC who do not investigate or report on the already devastated state of the world ocean, or possible solutions.

Hi Mr Opinion,

Yes eutrophication produced algal blooms that deprived those Menindee – Darling River fish of adequate oxygen, but from my point of view the nutrient involved was not just from, or due to, irrigated farms. Farmers are not stupid, they don’t waste fertilizer. Besides, farm runoff only occurs in association with rain, especially in this drought stricken region.

I think, just think, there are private enterprise aquaculture ventures underway in that Darling and/or Menindee region.
Aquaculture is now a major point source of nutrient overload pollution worldwide.
I think it’s also likely those natural waterways were overstocked with fingerlings released by government, leading to too many fish and not enough water and oxygen.

All point sources of nutrient have to be measured and assessed because it is the total nutrient load that sometimes becomes the pollution that causes the damage and destruction.

At present I am based working on a station north of Broken Hill while I assess the catchment and potential of steel aqueduct to bring harvested northern wet season rainwater (otherwise wasted), southward into the Murray Darling Catchment and eventually The Coorong.
But our ABC apparently could not care less, no known interest, just silence, even following publication of the suggestion in the Aus Govt Ag Comp White Paper – Supporting information, Index F, Fairfax JC. Here:

Though never give up.

Mr Opinion,
Only people with no understanding due to lack of sense compounded by UNI indoctrination describe it as such !
