I work with Hybrid Reefs out of Scripps in San Diego. Daniel is an amazing dude, Moore fellow, and prolific inventor. If you can help, there’s contact info on the website. https://www.hybridreefs.com/

Coral Vita is the trailblazer in the for profit category, first coral Series A (2025). I don’t know them yet though. https://www.coralvita.co

https://coral.org is a 501c3. One of my friends is on the board.

Other fun stuff.

Mars runs one of the most prolific programs: https://www.buildingcoral.com/

Reefstarter was backed by my friends at SOSV. They design coastal barriers. Great team. East coast for any of you Floridians. https://www.reefstarter.net/

There’s more but there’s a few off the top.

In general the US is primarily focused on erosion control since the beaches are disappearing. Coral is more an afterthought especially with the gutting of all our science. Australia is really leading the way here with AIMS and Saudi has KAUST. Big ups to the Paul Allen Foundation though, they gave Scripps $10M a few years back.

Fun stat to end with: coral reefs are responsible for over $10T in annual economic value. They get less than $1B a year to ensure they stick around. We’re gonna change that.

Here’s one successful example that only worked because of human intervention: https://www.sciencedaily.com/releases/2024/03/240308123248.h...

They can only survive short duration events. At some point the temp and time is too much and they die. The only way they come back is reintroduction.

We’ve lost over 50% of the reefs and are expected to lose 90% by 2050.

There are many amazing solutions. Some use corals more resistant to heat stress. Australia has seen some promising results with seed boxes. I know of a few other amazing solutions currently in the lab.

We have already gotten in natures way. So now we need to help nature with our technology.

I recall reading that the corals can reproduce both sexually and by cloning, with most in nature using cloning. The researchers brought them back to a lab and bred a bunch of them and found a lot of offspring could thrive in the warmer more acidic water, so they wanted to reintroduce them to a reef (or maybe they had). Been a while but it was interesting. Not sure what it takes to shift away from cloning in nature, but waiting for most the reef to die off seems backwards ;-)

I would suppose getting out of nature's way happens in one of two ways - infrequently because there is nothing of value in an area left to extract so people leave it alone, or infrequently because there is regulation forcing people to leave it alone.

Homeostasis, that was probably an option for most of nature in the 1950s or something, I think the damage is too great to just leave the reefs, forrests and other habitats to "fend for themselves". Even if what you say is true from an environmental perspective, we also have to fight to protect these areas from exploitation from fisherman, mining etc.

Isn’t this whole article about how they’re doing so right now?

https://en.wikipedia.org/wiki/Billion_Oyster_Project - Different effort, this one is about putting out living oysters, not just shells as GP was talking about.

And to be clear, in GP's link, living oysters do show up, but they weren't put there deliberately (the shells and every other development provided the larvae with places to grow and establish themselves). The NY project started with oyster larvae placed on discarded shells to deliberately create the new environment with an oyster population.
