Seaweed.

There perhaps is the CO2 from the person sitting next door to you.

low and behold, kelp forests emerged in shallow water.

Do you know how much algae there is in the world?

Live algae at 80 a pop?

Caulerpa taxifolia, the so called killer algae.

(Laughter)

So let's envision what the system might look like.

Algae. It infected marine life.

And the Molas there, you can find them with a spotter plane very easily, and they like to hang out under floating rafts of kelp.

And then you will be dropped into the ocean.

What we hope will happen is that the dolphin mimics the whistle, and if Diver A has the sargassum, if that's the sound that was played and requested, then the diver will give the sargassum to the requesting dolphin and they'll swim away happily into the sunset playing sargassum for forever.

We've also described another species of bipedal octopus.

I think it's the uh... I think it's the live algae in this one.

She's kind of teasing him and taunting him.

And I'm afraid of many, many more things besides that people can't even guess at,

wind blows out your candles, seaweed touches your face You scream.

A chef's salad, boss.

Get both and let her choose.

Now, when dolphins solicit humans for this game, they'll often sink vertically in the water, and they'll have a little sargassum on their flipper, and they'll sort of nudge it and drop it sometimes on the bottom and let us go get it, and then we'll have a little seaweed keep away game.

So Diver A plays the scarf whistle or Diver B plays the sargassum whistle to request a toy from whoever has it.

No sane person would think about using seaweed as a pattern for a shawl.

Is that her favorite?

Okay. One chef's salad, one fish and chips.

The chopped salad at Pastucci's.

Remember the seaweed? Armstrong and I placed it in your room.

But the Sargasso Sea, the same way it aggregates sargassum weed, actually is pulling in the plastic from throughout the region.

You always eat outside in, so to set for salad, we'll put the salad fork to the outside of the dinner fork and the salad knife to the outside of the dinner knife.

I have an extra egg salad on rye.

It'll be a piece of kelp.

Yeah, like the salad.

You're welcome to some salad.

But when the fish came back and began predating and controlling the urchin population,

Would you like some salad?

This is my supermarket. Not such a big one.

She never told me she didn't like chef's salad.

This is the Mediterranean coast with no fish, bare rock and lots of sea urchins that like to eat the algae.

All berries, especially goji berries and blueberries.

Would you like some more salad?

Please help yourself to the salad.
