Water abstracted for field irrigation varies according to climatic conditions and accounts for 25 to 40 per cent of the total amount of water abstracted.

At the Biology and the Built Environment Center, we carried out a study in a hospital where we sampled air and pulled the DNA out of microbes in the air.

Empty the drawer of its contents.

Thanks, I don't smoke.

Ventilator fans to full power.

Ventilator fans to normal.

Ventilate fans to full power.

It's two fans, one which he could turn from outside after he got the vacuum established, and he discovered that if he pulled all the air out of it, the one fan would no longer turn the other one, right?

One thing, he put a bird in there, and he pumped all the air out, and the bird died. So he said, hmm ...

Maybe he could use a little company.

And we also sampled the outdoor air.

It's like smoking without inhaling.

Sorry to mae you come.

I can't pump out any more double bottoms.

I'm afraid I can't manage that.

I wonder whether you'd be good enough to write the office.

Now we know room air is gloriously free, it is abundant, and it's already 21 percent oxygen.

All the desk drawers were empty.

No, I'm afraid we've drawn a blank.

I'm glad you were able to spare the time. Sit down.

I'll do my best to take you out on Friday

He gasps to the operator, My friend is dead.

A clever new gadget was described in a newspaper a few weeks ago. It pulls water out of the atmosphere and delivers you a glass of clean, chilled H2O.

Air.

She's asked for it so prettily,

Spare me a minute, sir. There's a Dr. John Holden outside, sir.

You don't have to answer right away. Take your time, think it over

But what he was trying to do was to pump all the air out of there, and see what would happen inside there.

I was hoping to hear a few gasps at least.

Hot air rises, and air is drawn in off the sea to replace it.

So what I'm first going to show you is air that we sampled outside of the building.

Not only that, because you have this convection, you have this rising of the air where it's hot, air is drawn in.

So, on the top, we had these beautiful rainforests and an ocean, and underneath we had all this technosphere, we called it, which is where all the pumps and the valves and the water tanks and the air handlers, and all of that.

You can't just drill a hole and pump it out.

Well, I hope it's not a wildgoose chase.

You do try to see her.

Air.

What about air?

Climate change is a really abstract thing in most of the world.
