Coral Restoration - Cultivating Mutual Symbiosis: Colleen Flanigan at TEDxMonterey

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