Today, readers comment on a desalination plant threat to a world-renowned breeding ground, River Murray pest control, planning, population and ministerial responsibility.

Commenting on the story: Fears Gulf desal plant will devastate giant cuttlefish breeding grounds
Are they mad? Is this, once again, about profits?
No desalination plant for this unique, giant cuttlefish breeding site. Quite simply, NO!
No No No. Can you hear us? No! Nothing more needs to be said. – Noris Ioannou
Wouldn’t it be cheaper and more environmentally friendly to connect the underutilised the Port Stanvac desalination plant into the Morgan Whyalla pipeline?
That plant is there at early 2000s cost so probably cheaper even if we have to increase pipeline capacity. – William Hecker
Commenting on the story: Weighing up a Murray carp kill
This information was very interesting. Surely now is the time to release the virus whilst the flows are high as this will clean the river of the dead carp quickly?
This is unlikely to happen as no one is game to make a decision. Nero fiddles as Rome burns. – Mos Hancock
Commenting on the story: Robodebt minister says not his job to check if scheme was legal
He used the ScoMo defence. He claimed to be a strong supporter of the Westminster system of ministerial responsibility, which means that a minister is ultimately responsible for his/her department’s actions.
Instead of trying to discredit those who criticised Robodebt, he should have tried to discover why and then remedy the situation, but that wasn’t the Liberal way. – Geoff Sauer
Commenting on Your views Wednesday February 1: Battle of the population forecasters: Yes, size matters
I wish to put a counter-opinion to that expressed by Graham Clews yesterday. In my view Australia has an enormous and almost totally undeveloped coastline capable of supporting many more cities, abundant natural resources, and a huge food surplus.
We should have a population of 100 million, if not more. Such a population could easily be supported without degrading the environment if it was done in an intelligent manner. I think the greatest problem facing the world today is not environmental (though that is a problem needing to be addressed), but population collapse in the next 100 years.
Unfortunately, Australians have a good reason to be wary of such population increases, despite the inarguable economic and national benefits that they would bring. That reason is the gross incompetence of all levels of government, Australia-wide, Liberal and Labor, in making even basic provision for the needs of an increasing population in terms of housing, infrastructure, public-transport, schools, hospitals, etc, as seen with the ongoing debacle at Mount Barker over many years.
The only idea governments seem to have is to bulldoze much-needed houses to build completely un-needed urban highways. The decision of the Planning Minister to reject a fairly mild proposal to build much-needed homes in an inner-suburban location is based on unadulterated NIMBYism.
Both Liberal and Labor for years have been (unsuccessfully) trying to increase South Australia’s population, but people aren’t going to come if they don’t have anywhere to live. If young people can’t buy a home here, they will leave. Unless we wish to become the retirement village of Australia we need radical change now to make it easier to, in particular, build more homes (and fast) and to increase public transport options. It’s not rocket science, but a political solution seems to be a long way over the horizon. – Kym Jackson
