Here's carbon dioxide, CO2.
These fuels are made of just hydrogen and carbon.
So when these crash into molecules of oxygen, as they do in your engine or in your barbecues, they release energy and they reassemble, and every carbon atom ends up at the center of a CO2 molecule, holding on to two oxygens, and all the hydrogens end up as parts of waters, and everybody follows the rules.
They're represented by corners between the bonds, and we also hide every hydrogen that's bonded to a carbon.
We know they're there whenever a carbon is showing us any fewer than four bonds.
Before there was life on earth, all the molecules were small, simple: carbon dioxide, water, nitrogen, just simple things.
Now, because the fate of water and carbon are tied to soil organic matter, when we damage soils, you give off carbon.
Carbon goes back to the atmosphere.
Now, if it does not decay biologically, it shifts to oxidation, which is a very slow process, and this smothers and kills grasses, leading to a shift to woody vegetation and bare soil, releasing carbon.
But fire also leaves the soil bare, releasing carbon, and worse than that, burning one hectare of grassland gives off more, and more damaging, pollutants than 6,000 cars.
All of that grass is now covering the soil as dung, urine and litter or mulch, as every one of the gardeners amongst you would understand, and that soil is ready to absorb and hold the rain, to store carbon, and to break down methane.
We are already doing so on about 15 million hectares on five continents, and people who understand far more about carbon than I do calculate that, for illustrative purposes, if we do what I am showing you here, we can take enough carbon out of the atmosphere and safely store it in the grassland soils for thousands of years, and if we just do that on about half the world's grasslands that I've shown you, we can take us back to pre-industrial levels, while feeding people.
A drug is made up of a small molecule of hydrogen, carbon, oxygen, nitrogen, and a few other atoms all cobbled together in a shape, and it's those shapes that determine whether, in fact, that particular drug is going to hit its target.
There's a dynamic mixture of acetone, isoprene and carbon dioxide that changes when our heart speeds up, when our muscles tense, and all without any obvious change in our behaviors.
I'm actually tracking the carbon dioxide you exhale in the room right now.
It's our collective suspense driving a change in carbon dioxide.
The only machine capable to capture the carbon that we are producing, always, even if we reduce them, everything that we do, we produce CO2, are the trees.
We are doing the sequestration of about 100,000 tons of carbon with these trees.
First, even if carbon dioxide emissions stopped today, global warming would continue.
Because the ocean gives us more than half of the oxygen we breathe, food, it absorbs much of the carbon pollution that we throw in the atmosphere.
And although a lot of that is about energy, it's also so much about carbon.
When a tree grows in the forest and gives off oxygen and soaks up carbon dioxide, and it dies and it falls to the forest floor, it gives that carbon dioxide back to the atmosphere or into the ground.
If it burns in a forest fire, it's going to give that carbon back to the atmosphere as well.
But if you take that wood and you put it into a building or into a piece of furniture or into that wooden toy, it actually has an amazing capacity to store the carbon and provide us with a sequestration.
One cubic meter of wood will store one tonne of carbon dioxide.
The carbon story here is a really good one.
If we built a 20-story building out of cement and concrete, the process would result in the manufacturing of that cement and 1,200 tonnes of carbon dioxide.
And I had snuck in this article on these things called carbon nanotubes, and that's just a long, thin pipe of carbon that's an atom thick, and one 50,000th the diameter of your hair.
And these are pretty cool because they only react with one specific protein, but they're not nearly as interesting as carbon nanotubes.
And so then, I was sitting in class, and suddenly it hit me: I could combine what I was reading about, carbon nanotubes, with what I was supposed to be thinking about, antibodies.
