If you fracture it, you can look at the fact that it's nanostructured.

The primary component of the most common form of sand is silicon dioxide.

This isn't Volvos this is volcanoes.

We need to breathe.

We stopped tilling, so that we could prevent greenhouse gasses from going into the air.

And that wasn't easy because poisons were everywhere.

Trees give off oxygen and absorb carbon dioxide.

Inert nitrogen, high concentration of carbon dioxide crystals, methane...

A very simple example is this When the world was primarily plants, the environment, which had carbon dioxide and some oxygen in it when they first started,

Tropical rainforests produce oxygen and consume carbon dioxide.

Where have essentially, you have an equal amount and very

The botanical names are in front of you.

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.

Each cylinder is about 10 percent ancient air, a pristine time capsule of greenhouse gases carbon dioxide, methane, nitrous oxide all unchanged from the day that snow formed and first fell.

We inject our own aerosols into the atmosphere, and we have trace gases, and not just carbon dioxide it's methane, ozone, oxides of sulfur and nitrogen.

So why is this relevant? Because when you put animals and plants in the same environment,

I mean, you can have blood flow, but at some point it's also going to want some oxygen.

Now, as we breathe, we produce carbon dioxide, and that carbon dioxide needs to be scrubbed out of the system.

And then above that, you're just adding more and more hydroxide.

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

This is regularly several hundred parts per million.

10 times better than our fog catching nets.

You see, hydrofluoric acid won't eat through plastic.

Then of course, there's all that

Makes the rocks crumble, and the first step in the generation of soil.

Carbon dioxide, having never gone above 300 parts per million, here is where CO2 is now.

The amount of carbon dioxide has increased by 10 percent.

So, carbon dioxide the stuff we want to get rid of not sugar, not anything.

As you can probably tell from its name, carbohydrates contain carbon, hydrogen, and oxygen.

But the real powers of this place come from phytoplankton.

So this breath is not just about exchange of oxygen and carbon dioxide.

So nature created a balance, and the balance was called animals.

More recently, into the Black Sea, where we're exploring.

And it puts 18 thousand tons of carbon dioxide in the air.

When the ocean absorbs a lot of CO₂, the water becomes more acidic.

Here's an interesting one for the IT world bio silicon.

It is the spectrum of a planet like Earth, showing a presence of nitrogen dioxide, as a clear signal of life, and oxygen and ozone.

It means it has eight protons.

Carbon dioxide is not a poison in itself.

I realize that they are microfiltration membranes.

My next step's gotta be oxygen.

The air we breathe in, or inspire, has a mixture of gases including nitrogen, carbon dioxide and oxygen, which is the most important for our survival.

Different amounts of UV hit different parts of the Earth at different times of year, so you can actually work out those stores of nitric oxide the nitrates, nitrites, nitrosothiols in the skin cleave to release NO.

What's a drug?

There are three basic limitations of scuba diving.
