Coral Restoration - Cultivating Mutual Symbiosis: Colleen Flanigan at TEDxMonterey
-
0:08 - 0:09Video: (Narrator) Anthropocene.
-
0:09 - 0:11A period marked by a regime change
-
0:11 - 0:13in the activity of industrial societies
-
0:13 - 0:16which began at the turn of the XIX century
-
0:16 - 0:19and which has caused global
disruptions in the Earth system -
0:19 - 0:22on a scale unprecedented
in human history. -
0:22 - 0:25Climate change, biodiversity loss,
-
0:25 - 0:29pollution of the sea, land and air,
-
0:29 - 0:31resources depredation,
-
0:31 - 0:33land cover denudation,
-
0:33 - 0:36radical transformation
of the acumen, among others. -
0:36 - 0:39These changes command
a major realignment -
0:39 - 0:41of our consciousness
and world views, -
0:41 - 0:45and call for different ways
to inhabit the Earth. -
0:47 - 0:49Colleen Flanigan:
This is a human's dining room. -
0:49 - 0:51It's a restoration experiment,
-
0:51 - 0:52where he left it alone
for a period of months -
0:52 - 0:55to see if it would restore itself
to the way it was -
0:55 - 0:57when he first bought the house.
(Laughter) -
0:57 - 0:59Or, he hoped maybe
it would renovate itself -
0:59 - 1:02and become what he was envisioning.
-
1:02 - 1:04But months later,
it's pretty much the same. -
1:04 - 1:06So for the next phase of his experiment,
-
1:06 - 1:11he's going to build a bar,
put up some walls and clean a bit. -
1:11 - 1:14Now, this is my dining room.
It's one of them. -
1:14 - 1:17It's a large table coral
with such a valuable investment. -
1:17 - 1:22You can see all the gorgeous coloured fish
attracted to the living space. -
1:22 - 1:24And my visitors — I have a lot.
-
1:24 - 1:27They just rave about
how magical and functional it is. -
1:27 - 1:30But, then a bomb blast —
-
1:30 - 1:32and someone dynamited for fish.
-
1:32 - 1:34Poseidon and I debate
about this all the time. -
1:35 - 1:37Do we jut leave it alone
and hope the coral reef rubble -
1:37 - 1:39will rise from the dead?
-
1:39 - 1:43Or, do we transform the destruction
and rebuild life-supporting habitat? -
1:43 - 1:47I say rebuild — using Biorock
mineral accretion technology. -
1:47 - 1:52To address the effects of human predatory
and parasitic symbiotic systems -
1:52 - 1:55that float throughout the ocean unchecked,
-
1:55 - 1:57what if people hone in
on specific needs of other species -
1:57 - 2:02and develop mutually symbiotic
relationships with other organisms, -
2:02 - 2:05besides their pets and house plants?
-
2:05 - 2:08Do corals just need
a surface to settle upon -
2:08 - 2:11like a shipwreck,
or maybe a million tires? -
2:11 - 2:14No, it's not a superficial problem.
-
2:14 - 2:18And will marine protected areas
be enough to ensure regeneration? -
2:18 - 2:21They may keep out commercial fisheries
and other visible invasions, -
2:21 - 2:24which is great, and important,
and necessary. -
2:24 - 2:26Yet, many of the threats are invisible:
-
2:26 - 2:31climate change, pollution,
decreasing alkalinity and disease. -
2:31 - 2:35Corals and their symbiotic beneficial
algae partners, the zooxanthellae, -
2:35 - 2:38have lived in harmony for thousands,
maybe millions of years. -
2:38 - 2:41The algae gives food and color
to the polyp animal -
2:41 - 2:43in exchange for protection.
-
2:43 - 2:45But with warming waters
and compound stress -
2:45 - 2:49they've been breaking up, and
they both suffer the consequences. -
2:49 - 2:51The corals starve, turn [unclear]
and white, -
2:51 - 2:53and the algae is probably eaten.
-
2:53 - 2:56It is sad. You can cry.
-
2:56 - 2:58There are some hopeful promising studies
-
2:58 - 3:02showing that corals may be adapting
to some of these increased temperatures. -
3:02 - 3:03And I hope so.
-
3:03 - 3:06I hope they can evolve
and adapt, and quickly. -
3:06 - 3:10But, right now, Biorock restoration
actively cultivates ecosystems. -
3:10 - 3:14It stimulates vitality
at the cellular and skeletal level, -
3:14 - 3:16and what better way to do this
than with electrolysis. -
3:16 - 3:19This might be just
what the polyps and algae need. -
3:19 - 3:23A three-way partnership that helps them
adapt to the traumatic trends. -
3:23 - 3:25So here's how it works —
-
3:25 - 3:28By running low volt direct current
through sea water -
3:28 - 3:32the limestone minerals, abundant
in the ocean, deposit onto metal, -
3:32 - 3:34and the resulting surface
is a natural substrate -
3:34 - 3:36for corals to settle on and colonize.
-
3:36 - 3:39It becomes a non-invasive mineral rock.
-
3:39 - 3:43The electricity locally raises the PH
creating an alkaline buffer zone. -
3:43 - 3:46This is important because with ocean
acidification and all the other factors, -
3:46 - 3:50corals have a hard time getting
the calcium carbonate they need -
3:50 - 3:52to build their excess skeletons.
-
3:52 - 3:54So essentially we're giving them
free skeleton, -
3:54 - 3:56so they can use their energy
for other vital activities, -
3:56 - 3:58like reproduction.
They can grow faster, -
3:58 - 4:02they can survive higher temperatures
that normally kill them. -
4:02 - 4:04The electrolysis appears
to increase their tolerance -
4:04 - 4:06to some environmental stress.
-
4:06 - 4:09Biorock was invented by architect,
Prof. Wolf Hilbertz, -
4:09 - 4:11as a building material in the '70s.
-
4:11 - 4:14It has high compression strength
and it's self-repairing in the ocean. -
4:14 - 4:17And he teamed up with Dr. Tom Goreau,
of the Global Coral Reef Alliance, -
4:17 - 4:20to develop coral restoration,
sustainable fishing -
4:20 - 4:22and permeable breakwaters.
-
4:22 - 4:25And it can be applied to oysters,
mussels and seagrasses. -
4:25 - 4:30I want you to imagine coral polyps
invertebrate animals calcifying -
4:30 - 4:32onto this aquatic topiary.
-
4:32 - 4:36So here is six years coral growth
in an area previously devastated -
4:36 - 4:39by dynamite and cyanide fishing.
-
4:39 - 4:41The minerals keep building up
because the limestone is porous, -
4:41 - 4:43and if you get really close,
if you're there, -
4:43 - 4:46you can see the hydrogen bubbles
fizzing up from the surface, -
4:46 - 4:49so as long as the electricity is flowing,
the chemistry is going. -
4:49 - 4:52There is about 60 coral arks
in Permuteran Bay in Bali, -
4:52 - 4:55home of the largest
Biorock nursery in the world, -
4:55 - 4:58and all of the native species
are represented. -
4:58 - 4:59The community is very much
behind the project -
4:59 - 5:03because it helps their eco-tourism,
supplies their fish stocks, -
5:03 - 5:05and they love natural beauty.
-
5:05 - 5:09I got to help weld, install and plant
the structure back in 2004 at a workshop, -
5:09 - 5:13and I just got this footage last week
from Thomas Sarkisian. -
5:13 - 5:16He is the electrical engineer
I'm working with on a project, -
5:16 - 5:18so I'm really very happy to be able
to share that with you, -
5:18 - 5:21because that place looked really bad.
-
5:21 - 5:26Now, for you do-it-yourselvers
I want you to see the basic steps: -
5:26 - 5:28design,
-
5:28 - 5:30weld,
-
5:30 - 5:31immerse,
-
5:31 - 5:33electrify
-
5:33 - 5:36— I'm hoping for
a self-contained power supply, -
5:36 - 5:37solders homeless fragments,
-
5:37 - 5:40attach with wires and pliers,
-
5:40 - 5:42and watch it grow.
-
5:42 - 5:45(Laughter)
-
5:45 - 5:48They're so sweet, thank you.
OK. (Applause) -
5:48 - 5:50Now, this is another sculpture in Bali.
-
5:50 - 5:52It's a little janky, it's called "Zigzag".
-
5:52 - 5:54It's a very zigzaggy, but I wanted
to show you the progression: -
5:54 - 5:56this is three months,
-
5:56 - 5:58two years,
-
5:58 - 6:01three and a half years.
-
6:01 - 6:04And after six years,
Liku Liku is overgrown. -
6:04 - 6:06The sculptures can be any shape or size,
-
6:06 - 6:09from the small coral skirt
to reefs miles long. -
6:10 - 6:11Maybe some tango dancers.
-
6:11 - 6:13If we can build a super highway,
-
6:13 - 6:16we can build a super reef.
-
6:16 - 6:18We already have artificial reefs thriving
-
6:18 - 6:22with 20 to 50 percent more biomass
than most natural reefs. -
6:22 - 6:24I'm talking about
decommissioned oil wells, -
6:24 - 6:27and rather than scrap them,
as most regulations require, -
6:27 - 6:31we could apply wave or tidal energy
to prevent corrosion, -
6:31 - 6:35and to provide an alkaline boost
to counter bounce ocean acidification -
6:35 - 6:37caused by carbon absorption.
-
6:37 - 6:39It's a great karmic twist.
-
6:39 - 6:42On my current living sea sculptures
inspired by DNA, -
6:42 - 6:44and I owe great thanks to all
my Kickstarter backers, -
6:44 - 6:48Harnisch Foundation,
Bertha Philanthropy, TED Fellowship, -
6:48 - 6:51and a team that helped me
to make it this far. -
6:51 - 6:53We plan to install it in the
Underwater Museum -
6:53 - 6:55in the National Marine Park of Cancun,
-
6:55 - 6:57to distract and lure the tourists away
-
6:57 - 6:59from the over-snorkeled natural reefs,
-
6:59 - 7:02and so it can become a coral refuge
and biodiversity study. -
7:02 - 7:05Science and policy are key
to coral health, -
7:05 - 7:08and I invite you to add
the arts into the equation. -
7:08 - 7:11Coral reefs are one of our planet's
oldest natural communities, -
7:11 - 7:14established reefs are
five to ten thousand years old, -
7:14 - 7:17and according to scientist David Miller,
-
7:17 - 7:19humans share similar
innate immunity genes, -
7:19 - 7:21so you're deeply connected,
-
7:21 - 7:23and if they are in trouble,
you are in trouble. -
7:23 - 7:25I've been talking a lot about
how we can help them -
7:25 - 7:29because they truly are our life support.
-
7:29 - 7:33I imagine swimming around this table
with all sorts of species. -
7:33 - 7:37Thankful, we were able to stimulate
mutual symbiosis in the Anthropocene. -
7:37 - 7:39Thank you.
(Applause)
