They isolate the chemicals and produce them at scale in labs. No dredging necessary. At least that's rumin8:

Reply to Lung cancer patients with moderate to severe depression at diagnosis are 2 to 3 times more likely to have inflammation levels that predict poor survival rates, a new study found. (n=186) by geoff199

I seem to recall seeing something a year or two ago talking about how chronic inflammation was linked to depression. So maybe the link isn't depression leads to inflammation but rather inflammation leads to depression

Reply to comment by thebeandream in Humans Started Riding Horses 5,000 Years Ago, New Evidence Suggests by geoxol

The Assyrians and Chinese did develop horseback riding, but each had to invent/adopt new technology in order to do so: the former, the martingale collar, the latter, stirrups. Apparently riding a horse bareback into battle means you’re likely to fall off and get stabbed!

Ah, thank you for elaborating.

I have read that seaweed is not a silver bullet, but it still seems viable just requires additional research and effort in accounting for complexities you describe. Nothing is easy.

Reduction efforts like the ones that you initially called for, and that most in the realm of sustainability often call for, also have the possibility to cause more harm than good as well.

Of course there are no easy solutions here, but there is this sort of anti-humanity sentiment that characterizes many "solutions", which are not productive (that's being charitable).

The problem with some solutions is they cause more problems than they solve.

Seaweed was one of those solutions we we forced to look at in Environmental Science 301.

It’s not that seaweed is bad it’s that on a large scale it starts to cause more issues than It solves. Always aim to do less harm than more :)

Reply to First archaeological correlate of the Egyptian rebellion described on the Rosetta Stone, 196 BCE — Evidence of violent destruction across the ancient city of Thmouis, in Egypt’s Nile delta, ca. 204-186 BCE by marketrent

Excerpt from the linked summary^1 by Jay Silverstein, co-author of the research paper:^2

>Professor Robert Littman, of the University of Hawai'i at Manoa, and I uncovered evidence of the civil war at Tell Timai – the ruins of the ancient city of Thmouis in Egypt’s Nile delta.

>The archaeological evidence has revealed widespread destruction from the time of the rebellion, 204-186BC.

>In 2009, evidence of burned buildings with ceramic vessels still in place first suggested that there had been a catastrophic event at Tell Timai.

>The destruction was widespread and followed by a levelling and rebuilding of the ruined city.

>Over the following years, evidence including weapons and unburied bodies that graphically pointed to an episode of extreme violence accumulated.

>Establishing the precise timing of events in archaeological excavations is difficult.

>The range from radiocarbon dating, for instance, is often too broad to provide a concise date that aligns with historic records.

> 

>At Thmouis, however, one room held evidence that allowed for more accurate dating.

>A hoard of coins on the floor dated to the reign of Pharaoh Ptolemy IV, while all of the coins from the levelling layer dated to Ptolemy VI.

>A dinner setting for four also had some distinctive vessels following an Athenian style that placed them in the first quarter of the second century BC during the reign of Ptolemy V.

>Thmouis was rebuilt as a city full of Greek colonists and soon became the regional seat of power as the Ptolemaic dynasty took power away from Egyptian temple priests who participated in the rebellion.

>The transformation of Thmouis from a small tributary town to a regional capital reflects the hand of an oppressive government that wanted to make sure that no major revolt from the people they ruled would ever pose a threat to their control again.
