Google Funds A Starfish-Killing Robot To Save Australia's Great Barrier Reef (abc.net.au)
"It looks like a tiny yellow submarine, but this underwater drone is on a mission to kill," reports ABC. Specifically, to kill the starfish that are destroying coral on Australia's Great Barrier Reef. An anonymous reader quotes ABC:
In a bid to eradicate the pest, Queensland researchers have developed world-first robots to administer a lethal injection to the starfish using new technology... Researcher Matt Dunbabin said the technology was 99.4 per cent accurate in delivering a toxic substance only harmful to the starfish.... Divers have played a big role in helping to combat the starfish, but Professor Dunbabin said the robot would take the efforts to the next level. "Divers currently control certain areas, but there are not enough divers to actually make a difference on the scale of the reef," he said. The drone can also monitor and gather huge amounts of data about coral bleaching, water quality and pollution.
"RangerBot will be designed to stay underwater almost three times longer than a human diver, gather vastly more data, map expansive underwater areas at scales not previously possible, and operate in all conditions and all times of the day or night," according to Researchers at the Queensland University of Technology.
The starfish-killing robots were partially funded by Google (through their Google.org Impact Challenge program to fund and support nonprofit innovators), reports The Drive. One study had found the reef's coral cover declined 50% between 1985 and 2012, "with nearly half of that drop resulting from the coral-destroying starfish species."

This particular starfish species is an invasive pest in Australia.

I thought, Google employees were very much against this sort of thing. And Electronic Frontier Foundation disapproves too.
Or is it only bad, when American military works on it?
Yeah, sure "fish aren't humans" — will the robot (particularly, the software) require much rework to begin killing, say, enemy divers?
In Soviet Washington the swamp drains you.
Humans are fucking up the environment, that is why the coral reefs are in danger. In the face of what humanity is doing on a global scale, nature can't take care of itself.
I don't know whether killing the starfish truly is necessary, but I suspect corals are ecologically more valuable than the starfish.
wrong
Seriously, Is it too much to ask that slashdotters keep up with the professional literature?
Would it not make more sense to catch them and make food from them?
Worst case cat food or dog food?
In some countries it is common to eat them: http://www.chinesestreetfood.c...

You must be new <looks at parent UID> errrr, <head asplodes> must not come here very often.
That study puts starfish as cause of 42% of coral losses per year. Seriously?
Reef has been there for hundreds, more likely thousands of years. Same for the starfish. Personal hypothesis: environmental conditions change (for example, sea water acidity), coral weakens as a result, and starfish take advantage of the situation.
Cause of death of the coral? Yes. Cause of the problem in the overall scheme of things? Hell no - external factors. It's those external factors we should be looking at. Not those starfish that do what they do once conditions are favourable.
Your'e a marine biologist, right?

Fortunately we already have drones capable of killing Australians. Starfish-killing drones are new.

Two major precipitating factors are nutrient runoff from Indonesian sugarcane farms, and global warming; both of which won't be solved any time soon, without a lot of international cooperation. This method is fairly unilateral,
Some states and canada are releasing wasps to kill ash borers. The ash borers are an invasive tree-killing species.
Wikipedia seems to be a little outdated, as they have not spotted the bugs in the PNW, and wasp are being used.

Lots of bad critters are being fought all over with interesting solutions.
Well, we let them do it though.
I didn't. I protested vigorously, but being only six months old, my angered cries were misinterpreted.
Asking whether the coral is more "ecologically valuable" than the starfish is premature, because we don't really understand the ecological relationship between the starfish and the reef. It is possible that the reef as we know it might not even be possible without starfish predation.
The crown-of-thorns starfish not some exotic species, it evolved with the corals it preys upon. Had humans never evolved, it would still be killing off sections of coral reef, only there wouldn't be anyone around to be upset at the pictures.
Now there are two possible justifications for humans intervening in the starfish/reef interaction. The first is if prior human actions artificially inflate the predator starfish population. The second is if prior human actions artificially weaken the prey coral population. In both those cases the sensible and indeed only feasible solution is to stop doing whatever it is we've been doing that creates the problem.
You can't eradicate an animal which lays twenty million viable eggs at a time by killing individuals, even on a massive scale. The very next year an area you to all visible appearances swept clean will be covered again. What you have to do is tweak the factors that alter the survival rate of those twenty million eggs.

How about sugarcane elimination robots, then? They can look like salt shakers and cry 'EX-TER-MI-NATE!' as they do their job.
Salt shakers vs. sugar, who will win?!
Corruption is convincing someone that the selfless ideal is the same as their selfish ideal.
The reef has not been around that long and has been routinely destroyed, quite a few times. The reef as we know it now was a coastal formation, well above sea level, for over twenty thousand years, before it was submerged around ten thousand year ago and started to regrow. It does have predators and will move away from a zone where to detects them https://en.wikipedia.org/wiki/.... In fact it is likely the lack of these that is causing the problem, because pretty shell and are more edible than their prey.
Google is simply indulging in an act of marketing, success or failure they don't care, they have been carrying on like a pack of shits and need to pretend to do some good deeds for advertising purposes. Especially invading everyone's privacy through master card, which you would think should be illegal. Financial institutions selling information about you financial transactions, especially say medical fees. Corrupt as fuck, truly disgusting.
Chaos - everything, everywhere, everywhen
The spike in crown of thorns starfish numbers is largely related to warming waters and increased sediment runoff from farms. Good luck fixing either of those quickly.
