Severe damage to ocean ecosystems is continuing due to mainstream media gagging of new information of substance including scientific assessments.

Since at least 2008 I have been stating there is more algae in the ocean, due to sewage nutrient pollution.
ALGAE is phytoplankton.

Not long after making my statements the mainstream media reported less phytoplankton, that plankton was decreasing.
Now however the link attached here forms evidence the media was wrong.
Especially note the last paragraph, just before the Bibliography.

The problem is solutions have not been put in place and so critically serious damage and impact and consequences are continuing, including starvation of whales and seabirds and increase in cost of fish and food world wide. Is Climate Change the only problem?

Why is mainstream media gagging and suppressing evidence indicating the devastated state of the world ocean and waterways?
Why?

http://wattsupwiththat.com/2018/03/15/the-phytoplankton-decline-is-there-anything-to-it/

Dear JF Aus,

I wouldn't rely on the media to effect change. These sorts of issues have already been brought to public attention by the scientific community for a long time. Especially the destruction of phytoplankton that would result from an ongoing depletion of the ozone layer. If the phytoplankton go then it's goodbye human race. That's why the big global corporations and governments came on board in the late 1980s in a concerted effort to eradicate the CFCs that break down the ozone layer. No phytoplankton. no oxygen for us homo sapiens!

By 'media' you mean mainstream media? If so, they might not have gagged information; they just haven't written about it because they don't know about, or if they do know abiut it, they don't consider reporting it will help sell their product, and/or their customers would not be interested.

You have found the information in what is obviously a branch of the media, so it's no big secret.

As the MSM are in the business of scare-mongering, and they have not used this information, they obviously don't think much of it, and neither would their customers, by their reckoning.

Dear ttbn,

After reading your post above and your comments on mainstream media it is now easy to see why you, Hasbeen, individual, Loudmouth and mhaze are all suffering from paranoid delusion. You're even starting make me think we might be under attack from Martians!

Look closely at mainstream media response to damage to our coastal waters that are supposed to be supplying adequate food to fish and animals of the Pacific Ocean. Google: mutton bird starvation. Google: starving whales.

The Australian ABC is funded to communicate, including to communicate national disasters and economic opportunities from solutions to serious problems. For example, reporting evidence of sewage nutrient pollution causing eutrophication and damage to GBR coral should lead to action and solutions. But no, there is silence and no public and political awareness, and therefore no appropriate resources for solutions.

Are Australian voters aware of need for resources for science to develop technology to reduce sewage nutrient in sewage wastewater instead of dumping it in the ocean?
Are voters aware of the northerly flowing longshore current driving the east coast of Australia sediment dispersal system that transports nutrient through GBR waters to Cape York and beyond?
Are politicians and the public aware of eutrophication in GBR waters and that acidification may not be the cause of coral bleaching?
Are voters aware the same sediment system current is transporting nutrient pollution into estuaries where it's feeding algae killing seagrass small fish nurseries that are supposed to be feeding Pacific Ocean tuna?

Can anybody show an example of where the GBR - longshore current - sediment dispersal and the sewage nutrient and eutrophication scenario, has already been brought to public attention by MSM? I think not. Absolutely not.

As for the public not thinking much of ocean ecosystem devastation, ask coastal communities if they are interested in solutions to why their amateur fishing tourism and local fresh seafood supply have collapsed.
ask anyone if they are interested in solutions to fresh local fish costing a fortune, unaffordable to most families. Fish, that not long ago was low-cost food for the poor.
Ask is anyone is interested in solutions to prevent whales and seabirds from starving to death.

Where has all this been reported? Its being gagged and suppressed.

MSM reporters show keen interest but editors put a stop to that. Why is that so?

Dear JF Aus,

I'm interested in all the things you are raising. (I think you will find that coral bleaching is caused by rising water temperature due to global warming, not acidification.)

Actually my particular area of interest and personal research in environmental sociology is Water. And I can honestly tell you that we are in big trouble.

The oceans hold 40% of CO2 and as the water heats up due to global warming it loses its capacity to hold it, releasing it back into the atmosphere where it acts as a trigger for a increased greenhouse effect making the planet hotter. Think of the ocean as a can of cold soft drink just opened; initially it is fizzy but left to stand it gets warm losing its ability to hold its CO2 and hence losing its fizz. Same with the oceans as they heat up. It's the warm water that kills the living part of coral thus losing its colour colour and going white.

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.

Joe

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:
http://agwhitepaper.agriculture.gov.au/supporting-information/published-submissions-green-paper

Though never give up.

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

what happened at Menindee when all of those fish were killed in the Darling?
Mr Oipinion,
My guess is it was lack of oxygen due to the lack of flowing water due to the milking by Cotton growers. Of course, academic scientists will prove otherwise with the help of MSM.
So far as the dying coral goes it's plain & simply pollution. I have seen quite many new coral patches developing in the northern sections over the past few years. Once the chemicals from the Coral Sea WW2 shipwrecks & the Ok tedi Gold mine outflow have dispersed, the reef will begin recovery in earnest. It will be interesting how the industry dependent MSM will report that.

Hi JF Aus,

Could you please let me know of any articles you come across that you think might be of interest to me? I'm primarily interested in what the scientific community and scholars are saying about water, particularly its connection with people and their societies.

particularly its connection with people and their societies.
Mr Opinion,
While you're waiting, I'd like to offer my utterly un-scientific, un-scholarly opinon. I have worked in the water industry for many years & have only this experience to draw on.
It goes without saying that all life on this planet needs water to exist. Then you have people who use water to make money for the simple reason that humans need water. That is the freshwater part. Saltwater harbours all the food humans can drag out of it to consume & of course make money.
I'm looking forward to read a scientific, scholarly view on water.

Dear Mr Opinion,

I'm not sure if this is the type of thing you're
after, but here goes:

http://www.livescience.com/topics/water

I'm not sure this is a case of the "mainstream media gagging and suppressing evidence".

Its more a case of that's just the way the world works these days, especially the media world.

Less plankton equals more news-worthy. Less food for whales, OMG. Another species dying out just as all hte doomsayers said. Of course this gets a run in media using the age old premise of "if it bleeds, it leads".

But stories that things are OK or there's even more food for the whales and that the doomsayers were wrong (AGAIN) just doesn't cut the mustard in terms of what the MSM thinks the public wants or needs to know.

So no conspiracy, just business as usual.

Massive heat-waves in France - top story. Unheard of snow in Poland - who cares. That doesn't fit the narrative.

I'm not sure why possibly more plankton is "evidence indicating the devastated state of the world ocean and waterways?" Seems like a good thing to me. And I to recall reading that increases in phytoplankton is likely caused by CO2 fertilisation. Indeed there were proposals to add iron to the oceans to encourage plankton growth and the consequent absorption of CO2.

Dear Foxy,

Thanks, much appreciated.

PS Would it surprise you if I told you that environmental issues are socially constructed?

Mr Opinionated,

So that's what they're teaching in first-year uni these days ? That environmental deterioration somehow is socially constructed ? Gosh, who worked that out ?

For god's sake, take it for granted, Opinionated. How else ? Wait until you get into your studies, you might find even more evidence of social construction, going back hundreds of years. Thousands of years in some places.

Joe

Dear Loudmouth,

It's clear to see that you do not understand what I mean by socially constructed.

mhaze,

You have really been brainwashed.
Why are you talking nonsense about CO2 and iron, when it is the total load from various point sources and various nutrients that together promote growth or sometimes amount to pollution and damage.

Why is Australian MSM going on and on about warming and acidification, while not reporting and encouraging debate about eutrophication killing GBR coral?
N.B "in denial".

Att: Mr Opinion.

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3946114

Dear JF Aus,

Thanks for that, much appreciated.

I see you have summed mhaze up. There's a few of them in his group like Loudmouth, Hasbeen, ttbn and individual. They think the scientific community is lying to them and trying to do them harm. They stand for anything that refutes what the scientific community is saying no matter how ridiculous or irrational it is.

They think the scientific community is lying to them
Mr Opinion,
I don't think that at all. I just happen to realise that many within the scientific community don't lie, they just don't know. Big difference !

Dear individual,

Now you're in denial about being in denial! Why don't you just change your name from individual to The Quinella Kid so that you can always have it both ways.

Mr Opinion,
What denial ? Do you know the meaning of the word ? Scientists are too inconsistent because that's the nature of guessing ! We, bystanders can see the many conflicting & changing views published, hence our mistrust in many scientists.

"Why are you talking nonsense about CO2 and iron,"

Well I was simply pointing out that, while you think that increasing plankton numbers (if indeed they are increasing) are an unmitigated disaster, others think its a nett good.

"Why is Australian MSM going on and on about warming and acidification"

Well I thought I explained that. They are a business and their business is telling scary stories that will sell their product. Whoever sold you the notion that the MSM is about unbiased education and presenting both sides on every minor issue, really sold you a pup

Hands up all those who have busied themselves investigating "eutrophication killing GBR coral" since they have received the shocking news that the media has been keeping secrets from us. I would have thought the media has done enough damage already, with its lies about the global warming fad and the 'death' of the GBR.

Goldfish type memories and lack of historical knowledge mean that people with only a passing interest in anything that doesn't affect them directly are not aware that there have been hysterical fads and predictions of doom - all false - since the dawn of time.

I'm scuba diving on the northern GBR several times every season, I wonder how many OLO'ers are ? The reefs are bouncing back. If the tourist & recreational fishing boats can be kept away then all will be good again.

I see Mr Opinion is in good company with JF Aus, who still thinks the Australian east coast current is a north going current, & obviously refuses to do the research to get the facts.

Like all greenies he avoids like the plague, any fact that would destroy his pet theory.

Has been,

This really is a case of what you say about other people is what you are yourself.

There are two currents on running in opposite directions off the east coast of Australia.
I posted two links about them previously for you but you ran away.

I will post them again if you agree to discuss them.

https://eatlas.org.au/media/3566

The above is for JF Aus & Hasbeen

Att: Mr Opinion.

Re Hasbeen arrogantly claiming there is one current.

There is scientific proof of two currents, one being the northerly flowing longshore current taking nutrient pollution into GBR waters causing eutrophication, the latter that is in critically urgent need of solutions.

Google: abstract the sediment dispersal system on the southeast margin of australia boyd.

N.B. The last paragraph of that abstract states:

The eastern Australian margin on average is less than 50 KM wide, but thus contains two major sediment dispersal systems heading in opposite directions.

Dear JF Aus,

Like I said elsewhere, Hasbeen belongs to the group of denialists, which includes ttbn, individual, Loudmouth and mhaze. They're suffering from paranoid delusion, thinking that the scientific community is lying to them and trying to do them harm.

I think they might be former creation scientists who decided to become climate change denialists when people started to debate about global warming. You just have to take what they say with a grain of salt. We can only hope that they keep taking their anti-psychotic drugs and following their psychiatrist's instructions.

Hi Mr Opinion,

If at least some of those people are as you say, there must be others like them. That could be why solutions to many problems are not being put in place. For example.

There is denial of an Aus east coast northerly flow of sewage nutrient pollution into GBR waters. Consequently there is failure to understand impact on the environment and society, and consequently solutions are not being discussed and put in place. Therefore relevant damage and destruction is continuing and worsening.
And result of that is in your field of interest, downturn in international tourism to the GBR and throughout Australian society.

There is much more to this.
Even the GBRMPA is in denial of the northerly flow of nutrient pollution into GBR waters, they say nothing about it in their GBR science.
And consequently damage is continuing and worsening, including exponentially.

Dear JF Aus,

You have hit the nail right on the head: the root cause of environmental issues is that the issues per se are socially constructed. (PS: I don't think the denialist mob will try to refute this because one of them viz Loudmouth demonstrated earlier that they don't have a clue what a social construct is.)

they don't have a clue what a social construct is
Mr Popinin,
I have to admit I'm not right up there with the social "experts" however, I'm guessing that it means the outcome of social engineering over the past 5 or so decades is the dysfunctional society we have now ? People suing others for their own stupidity & moron Judges award them damages !
Looks to me what we really need is social de-construct if the recent past/present is anything to go by !

And consequently damage is continuing and worsening, including exponentially.
JF Aus,
I won't argue your point because I'm not enlightened on this but I would like to ask if you could put forward your suggestion for a possible solution. It undoubtedly all goes back to too many humans polluting the Planet.

How typical of sociologists & greenies, any theory they dream up is better than proven facts. Mr O, & JF Aus want to believe the Australian east coast current is a north going current, so it must be so.

The fact that radio buoys have been tracked a number of times proving the whole drift is to the south has no effect on them believing their own garbage. Yes sometimes a back eddy can to move on a big ellipse, but the flow is south. Sydney toilet paper ends up in Bass straight, not the reef.

I doubt either of them have ever been out to sea to test their theories. If they had, they would have seen the lobster pots buoys streaming south, at times dragged south so hard by the current, they are dragged under water for extended periods.

They could of course ask the sailors who have sailed the Sydney Brisbane race. They well know there are back eddies in the current going north along some of the deeper beaches. It is only a narrow bit of water, & only in the deeper bays, but it is critical when sailing on light wind nights to sail in close to the beaches to get out of the south going current, that can easily carry you south, & into the counter eddy. Those eddies never get past the headlands.

That great yachtsman James Hardy, when giving a talk to yachtsmen about to do their first Brisbane race, told them to sail in very close to the beaches. When asked how close he famously stated "if you can't hear the dogs barking, your too far off".

I get so sick of these clowns calling anyone stating facts they don't like, denialists, while spouting the utter garbage they believe.

There, no stop arguing !

Individual,

F.y.i.

No worry but I can't go to your link at present because I am presently using a smartphone and can't copy and paste that inactive link. Later this morning I will use my laptop and get to it.

If you delete the s off the https when you post a link on OLO, the link will become active. Graham explained the OLO system does not recognise the s.
Cheers.
JF.

Dear JF Aus,

Good luck with trying to get Hasbeen and individual to understand anything. If you show them that white is white and black is black they will still call both grey! They are so full of paranoid delusion that the scientific community is lying to them and trying to harm them that I don't even think their psychiatrists will ever be able get through to them.

Mr Opinion,
Please don't give up on Individual. He/she does not have the same attitude as Hasbeen, who has changed with more negativity recently.
I value your input because there may be others similar to Hasbeen, for example at the top of GBRMPA and JCU science that do not include the northerly longshore flow of elevated nutrient water in their GBRMPA science.

Individual,
Here is your now active link.
http://www.researchgate.net/figure/Schematic-of-the-main-ocean-currents-off-eastern-Australia-Surface-currents-are-shown-in_fig2_228492387

In response:
The link shows a schematic main OCEAN currents off eastern Australia, determined main currents, not ALL currents.
In terms of biological value I submit a main current is the alongshore/longshore current that drives the Australian east coast sediment dispersal system that supplies natural nutrient, and now also sewage nutrient pollution, to seagrass nurseries and coral ecosystems that provide food to fishes and other animals of the Pacific Ocean.

The Australian CSIRO advised me the alongshore/longshore current is insignificant and therefore has not been named.
However I have evidence the Australian east coast longshore current is very significant, because it is the northward flowing current that, apart from biological value, also transports sand used with cement to build City of Sydney high-rise and housing and other infrastructure.

If ABC or other MSM reported insight to Australian east coast ecosystems and currents more people would understand the need for solutions to the cause of damage and destruction of the GBR and estuary food web nursery ecosystems.

If there was general knowledge of the need I think genuine scientists would not be afraid of losing grant support for their livelihood and would apply to explore scientific evidence required to get solutions underway.

The ABC and MSM cannot deny there is a powerful current that transports heavy sand northwards along beaches and past cliffs, sand that sometimes blocks estuaries and has to be dredged to send sand onward, northwards.

Yachties never sail close enough to dangerous beaches and cliffs so therefore don’t experience the significant northwards flow of alongshore or longshore current as it is called, but it’s there and is transporting sewage nutrient pollution, gagged by MSM

Individual,

Is the problem too many humans or too many uninformed humans, ignorant due to ABC MSM gagging?
If humans were informed through genuine general communication so debate could take place it would be possible for politicians and public service managers to better understand some of the problems and solutions.

I agree there is a great deal of existing specific knowledge, but there is not a lot of general understanding of that knowledge from an individual point of view.

Example, I have evidence of substance pertaining to malnutrition and seafood dependent people and ongoing damage ocean ecosystems linked to that malnutrition continuing and worsening, yet I am presently based and researching catchment near Packsaddle NSW, looking at feasibility of solutions.

I don’t want to do all this by myself. MSM should be sharing the opportunities form solutions, such as development of more business and employment and prosperity for farmers and other people worldwide. The water ecosystem of this planet and its problems and solutions involves everyone.

Not far away there is a pipeline transporting natural gas from Moomba to Brisbane and also Sydney. Each day both those cities dump fresh water loaded sewage nutrient into waters of the Australian east coast sediment dispersal current that flows northwards where nutrient is proliferating over abundance of algae causing hypoxia and eutrophication.

Imagine if/when the Moomba gas pipeline reaches its use-by date and could be retrofitted with solar powered water pumps to reverse the flow and transport fresh water with nutrient far inland. Or consider a new black polythene pipeline could be installed for water in the same almost-straight gas pipeline corridor.

Developing infrastructure for less nutrient pollution in ocean ecosystems while also increasing more water and fertilizer supply for farmers. Increase exports. Why not?

I am also assessing feasibility of using deep steel aqueduct to harvest and transport northern Qld wet season water into SE Qld, NW NSW, into the Murray Darling, so as to also relieve stress on the water-starved Coorong.
The Coorong should be feeding southern ocean fish for fisheries.

Inland and ocean insight is involved. Savvy?

northern Qld wet season water into SE Qld, NW NSW, into the Murray Darling, so as to also relieve stress on the water-starved Coorong.
JF Aus,
Welcome to the Bradfield scheme support group !

Individual,

As far as I'm aware, the Coorong is outside the Goolwa Barrages, and it's saline, getting fresh wash from the tides, at least at its western end. The river water is deliberately trapped behind the Barrages, and maybe a metre below the high tide level. I don't think the Barrage workers flush fresh water into the Coorong at low tide, but I could be wrong.

Joe

The Bardfield Scheme to my understanding was to pump fresh water from rivers east of the Great Dividing Range, up over the range to land and rivers west of the range.
I think the scheme failed to go ahead because of the very high cost of pumping significant amounts of heavy water up and over the range.

The system I suggest is to harvest intense wet season rain in the upper catchment of the Gregory Range, then decant it from holding areas into aqueduct running southwards.
The suggested aqueduct would remain as high as possible and almost level along the range, following the contours, winding in and out around valleys as it takes water southward.
No pumps are required so no cost there.
In fact I think hydropower would be possible in a few areas.

The idea is to harvest excess water that normally flows wasted into the Gulf Of Carpentaria. This is not about dams on existing rivers, or taking water from inland rivers.
Its about harvesting from the high catchment with remote and control of the harvest and flow.
The system would not stop rain and river flow on the lower catchment. If there is no penny pinching in development it could perhaps also enhance inland river flow, such as to Lake Eyre.

I think high catchment of the eastern side of the range could also harvest presently wasted fresh water supply, through relatively short tunnels plus steel aqueduct.

No doubt many people have thought of sending east coast water inland. Obviously, the key is doing it economically. And now also to benefit the ocean.

JF Aus,
This is the first time I heard the term pump in relation to the scheme. I have to do some deeper reading there. I'd have thought dams & weirs & possible some tunnels were planned to change the flow west. It doesn't actually have to flow straight through straight away, as long as the artesian basins are replenished to capacity the water will start flowing on the surface. The Greens won't need to worry about desert rats etc drowning because because their instincts will tell them to climb higher when their butts get wet wet, unlike some greens who'd probably just sit there & drown.
Anyhow, sooner or later they will construct it because they'll have to.

One of the big polluting factors is run-off due to excessive built-up area. Water does not get a chance to filter through the soil into the ground & simply runs off into the waterways to the sea, taking along pollution.

Dear individual,

What you call run-off, the agribusinesses call irrigation.

Mr Opinion,
Run-off comes from built-up area not farms. Farms have soil/grass that absorbs water. Carparks, massive supermarkets, sporting facilties etc. have concrete that causes run-off !

I have long said we should build run-off collection ponds on city outskirts in the form of lakes, canal real estate & widening instead of narrowing river courses.

Dear individual,

I was being facetious, given that more than 80% of irrigation water is actually wasted.

http://www.ranops.net/news-and-interest/abfc-roebuck-bay-grounding.html

I wonder about the impact on reef & ocean of larger versions of such incidents !

In the days of Bradfield they would have had to use positive displacement pumps to push water up over the mountains, probably steam driven with lots of moving parts and wear and tear. These days an inline series of solar powered turbine type pumps along the route are available to run by remote control with virtually no maintenance. Its not a matter of getting bulk water inland, its need to get concentrated nutrient away from coastal waters.

It's dissolved nutrient pollution causing the damage, not silt, not oil or industry chemical pollution.

80% of irrigation water is actually wasted.
Mr Opinion,
Yes & no, if it seeps back into the aquifer good, if it runs to sea good, if it evaporates good but if it gets polluted then it's a definite no good !

Steel aqueduct will overcome a majority of seepage and steel aqueduct can be demountable.

Steel aqueduct with less seepage in canals taking bulk water to irrigated crops can mean more water for the environment.

Why is mainstream media gagging and suppressing and hindering development of modern infrastructure of benefit to the environment and business and employment?

JF Aus,
Because it could be achieved without academic "experts" involved, no finger in the pie so to speak !

Beats me why at least the ABC is not looking into such national economic opportunities.
No wonder Australia is going nowhere.
Backwards really.

Just look at Australia's fuel shortage, but I guess the worsen shortage will force up prices that will increase excise tax, and government will be very happy about that.
Why has the ABC not stood up for keeping Australian owned oil refinery?
Also, why no ABC investigative reporting or push for low cost natural gas for our vehicles in this vast long distance country?
