There is a chemical that's called perflubron.

In all of this time, 650,000 years, the CO2 level has never gone above

It's an absurd idea.

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

We need to breathe.

My next step's gotta be oxygen.

What's a drug?

There are three basic limitations of scuba diving.

This isn't Volvos this is volcanoes.

And then you have two extra pairs of valence electrons in the oxygen.

These granules contain three essential plant nutrients.

This was a different record.

It's here, the brain.

Meanwhile, the human body consists of 65 oxygen, 18 carbon, 10 hydrogen, and 7 of various other elements including 0.002 of silicon.

(Laughter) (Applause)

Oxygen, people.

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

And there was no carbon and oxygen in the universe throughout the first generation of stars.

It appeared dead.

High oxygen content.

Oxygen! Yes!

Pure oxygen.

Oxygen, yes. Thermal garments...

What's the O2 stat?

Give me an O2 stat.

Iron and oxygen are elements.

Water contains hydrogen and oxygen.

Liquid hydrogen and oxygen.

Trees give off oxygen and absorb carbon dioxide.

The oxygen here is two percent of normal.

Tropical rainforests produce oxygen and consume carbon dioxide.

Nitrogen bonds to oxygen, which in turn....

And after the toe cells have kind of taken out whatever they need.

I'm H2O intolerant.

You need oxygen to breathe.

It sucks all the oxygen out of this room.

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

And so the electrons spend a lot more time around the oxygen than they do around the hydrogen.

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

Oxygen and hydrogen make water.

Where have essentially, you have an equal amount and very

So, I would sleep in a hypoxic tent every night.

How you doin' on air?

Doctor, the patient is desatting.

O2 sat's down 82 percent.
