The other reason is this amazing bush glows.

The reefs of the Dead Sea.

and coral reefs and rakishlooking craft in the offing.

They're things like this.

What planet are these people on?

He does not hear it.

A great deal of this has been happening in the Great Barrier Reef, particularly in coral reefs all over the world.

look at light, look at patterns.

That one on the right is about five feet high.

So we had our own miniature rainforest, a private beach with a coral reef.

So we went and taught the techniques. We did workshops and lectures.

Laden with raccoons, gold, silver and coral... the treasure ship sailed away down the river.

And you show up, and it's dead.

So when we think about scaling up metabolic materials, we can start thinking about ecological interventions

Simulates coral growth, albeit somewhat slowly. Written by Frederick Roeber 1997.

The people in Chicago decided that as well as exhibiting our reefs, what they wanted to do was have the local people there make a reef.

It's almost impossible to model this structure any other way, and it's almost impossible to do it on computers.

Plants and organisms that make shells, coral, think of it as a building block.

There is now a cement manufacturing company starting in the United States called Calera.

On the left is water coming through the shore, taken from a NASA satellite.

And if the bleaching doesn't go away if the temperatures don't go down reefs start to die.

So in 2007 we had an exhibition, a small exhibition of this crochet reef.

In each of these cities, the local citizens, hundreds and hundreds of them, have made a reef.

And by the way, the reason the kittens here are orange and these are green is because that's a bioluminescent gene from coral, while this is from jellyfish.

And I don't know whether they actually saw crab in it, or imagined that one might be, but whatever the case, they would leap off the bottom and go through the water and land right on top of this coral head, and then the web between the arms would completely engulf the coral head, and they would fish out, swim for crabs.

And indeed there are now thousands and thousands of models that people have contributed all over the world as part of this.

Corals are very delicate organisms, and they are devastated by any rise in sea temperatures.

And they would see a coral head, maybe 10 feet away, and start moving over toward that coral head.

But it turns out there is a very good reason why we are crocheting it because many organisms in coral reefs have a very particular kind of structure.

And we've got this 3,000 square foot gallery and we want you to fill it with your reef.

The bottom is transformed from, in this case, a hard bottom or soft coral into a muddy mess.

Of course evolution is somewhat random, and you know, about 55 million years ago there was this rebellious little puffer fish faction that said, oh, the heck with the coral reefs we're going to head to the high seas.

I'm haunted by the thought of what Ray Anderson calls tomorrow's child, asking why we didn't do something on our watch to save sharks and bluefin tuna and squids and coral reefs and the living ocean while there still was time.

Where is Meishan?

Ocean acidification is a really big issue that people are concerned with, as well as ocean warming, and the effects they're going to have on coral reefs.

Now it's reversing that equation, and actually sequestering half a ton of CO2 thanks to the recipe from the coral.

But gradually, as the buildings are repaired, we will see the accretion of a limestone reef beneath the city.

My sister and I started this project in 2005 because in that year, at least in the science press, there was a lot of talk about global warming, and the effect that global warming was having on coral reefs.

I'm here today, as June said, to talk about a project that my twin sister and I have been doing for the past three and half years.

On the scale of decades, in our lifetimes, we're going to see a lot of damage to coral reefs.

And the reason that is, is because in a place like this island a lot of the sand is made of biological material because the reefs provide a place for all these microscopic animals or macroscopic animals grow and when they die, their shells and their teeth and their bones break up and they make grains of sand.

And it's destroying that precious benthic community on the bottom, things like sponges and corals, that critical habitat for other animals.

Redhead, redhead.
