(Laughter)

When you shine light on them, you can see them bubbling.

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

Carbon monoxide is a poisonous substance formed by the incomplete combustion of carbon compounds.

If you could get a deal at Copenhagen, where people agreed,

No living things could live without oxygen.

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.

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

We need to breathe.

But the real powers of this place come from phytoplankton.

You can't live without oxygen.

What is it? Parasite in his bloodstream choking him of oxygen.

Nitrogen, oxygen. Looks like enough CO2 for green leafy things.

My next step's gotta be oxygen.

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

It thermalized his lungs. Initialize the hyperbaric sequencer.

What's a drug?

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.

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.

Well, in the context of diving, you get too much, you die also.

Now, because the fate of water and carbon are tied to soil organic matter, when we damage soils, you give off carbon.

These granules contain three essential plant nutrients.

This was a different record.

It's here, the brain.

No matter where on Earth you live.

Oceans come and go. Mountains come and go. Glaciers come and go.

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.

It appeared dead.

High oxygen content.

Oxygen! Yes!

Pure oxygen.

Oxygen, yes. Thermal garments...

What's the O2 stat?

Give me an O2 stat.

Now think about that.

Massive amounts of carbon dioxide are generated every day.

Iron and oxygen are elements.

Water contains hydrogen and oxygen.

Liquid hydrogen and oxygen.

Well, given the environmental conditions... the lack of oxygen and light... and their impact on his biological development, he could be significantly older.
