I find these flippant comments rather annoying where it only seems that the poster has geniusely summarized the whole article with their acute senses

> poster has geniusely summarized the whole article with their acute senses In fact they haven't even genuinely summarised even the quote they have half-copied. Let alone the article. > I find these flippant comments rather annoying What I find annoying is the tendency to drag half a sentence out of context and parade it around as if that proves some point.

for >90% (a made up stat) of the population, it does though. the majority of people are too lazy to double check any of the information they learn from whatever source they are receiving it. the people making these edits know this. they lose no sleep at night about it.

I can understand how this would reduce erosion (although that benefit would seem negligible ROI vs (concrete?) wall dam engineering) but how is an undersea wall going to even partially reduce flooding, exactly?

Looks like it will act similar to rock armor (around 9:00 in the video)

The front page image is bothering me: are they really placing shells inside plastic nets? Aren't nets a big pollutant?

How come probably the most important intervention, building sea walls around Manhattan et al, isn't happening?

I've long thought that eventually the SF Bay will be dammed, with locks, etc, at golden gate.

There is a museum in SF that shows exactly what would happen if that were to happen. It was proposed in the early 20th century. The conclusions from those experiments they did was it does not end well for most of the bay area if that happens.

Only if they’re drifting.

Well, sea level rise from climate change isn't gonna end well for most of the bay area either.

Floods and thus investment in better flood prevention will only increase in the coming decades, it will be interesting what innovative solutions that spawns. It seems like even this century-old branch of engineering still holds room for experimentation with new methods. Interesting that this particular project is run by a nonprofit. I hope it works out.

Flood prevention will become such a huge industry that everyone will have to move to coast.

I've always assumed that Halliburton has a plan to corner the market.

I've volunteered a few times with the BOP and it's a really great experience. Would recommend if you're in NYC! https://www.billionoysterproject.org/volunteer

Hard to get a spot generally!

aw, shucks! well, when life gives me a lemon, guess I'll take my oysters and go home!

If you're ever in the area check out the US army Corp of Engineer's Bay Area hydraulic model. It was built 70 years ago to simulate the effects of one such proposal.
