And why?

It has many consequences.

The main framework material of coral reefs is calcium carbonate.

And I asked them, what is scaling? What's inside your pipes?

So, fungi and mycelium sequester carbon dioxide in the form of calcium oxalates.

And they said, calcium carbonate.

At some point, as this transience, as this CO2 uptake in the ocean continues, that material's actually going to start to dissolve.

When you evaporate seawater, the first thing to crystallize out is calcium carbonate.

It's possible because the mycelium produces oxalic acids, and many other acids and enzymes, pockmarking rock and grabbing calcium and other minerals and forming calcium oxalates.

Oh, by the way, just in case you weren't already guessing, it's calcium carbonate.

From this, we can detect an extraordinary number of things.

Sodium, potassium, calcium.

It's not different, it's the same stuff calcium carbonate, calcium carbonate.

They can pull calcium out of the environment, and put down a layer of calcium and then carbonate, calcium and carbonate.

This abalone shell is a biocomposite material that's 98 percent by mass calcium carbonate and two percent by mass protein.

Calcium. Calcium is only .25 .

These proteins are very negatively charged.

And that builds up on the evaporators and that's what that image on the left is gradually getting encrusted with the calcium carbonate.

The will of calcium and sodium

Oh, wait a minute. What about calcium? Calcium's not a trace.

Aluminum buffer action, aluminum hydroxide is what we think it is, uh, plus the barium carbonate, strontium titanate, strontium oxides, barium oxides, probably some aluminum oxides in there.

Calcium is absent from his diet.

So what we're doing at the moment is we're accumulating metals

And this is an amino acid.

Acid rain from cities and industries leeches the soil of vital nutrients, such as potassium, calcium, and magnesium.

Acid?

Puffuffuff, what?

Like 46 percent of the crust of the earth is oxygen.

Before that, they were all soft, fluffy structures.

Arlene told me people are less calciumdeficient than they used to be because of all the fancy coffee they drink nowadays.

And you could also know that what you're dealing with is a strong acid.

sulfuric acid.

Well it turns out, we have many different alternatives for such a set of building blocks.

In particular vitamin B1, which is thiamine,

Acid for blood.

My next step's gotta be oxygen.

Ammonium dysterate.

Methyl isocyanate.

There are three basic limitations of scuba diving.

For example, we might say that, and this isn't the actual code, but maybe UAC, and I should look these up.

This isn't Volvos this is volcanoes.

So which means that it's really impossible to find an object where you find about 10 times more sulfur than silicon, five times more calcium than oxygen.

That's what we use to inject, as we start to do our deep dives.

We need to breathe.

Unlike nitrates and peroxides, it gives off no signature.
