The ABC TV science program, Catalyst, recently reported on -
"There’s one place in the world where a quarter of a million of Giant Australian Cuttlefish migrate each year for a spectacular love-in. The problem is, their unique nursery may face a mortal threat."
The mortal threat is the discharge of concentrated brine from a desalination plant - planned to produce 200 megalitres of fresh water per day for mining operations at Olympic Dam in South Australia. For more on the ABC TV Catalyst program, see the Catalyst website here.
For a variety of options to use concentrated brine as a positive resource, and avoid the risk of environmental damage by treating it as an unwanted "waste" to dump somewhere, have a look at the following collection of ideas available on the web.
