0:00:00.928,0:00:04.012
Everything is interconnected.

0:00:04.012,0:00:07.538
As a Shinnecock Indian, I was raised to know this.

0:00:07.538,0:00:09.561
We are a small fishing tribe

0:00:09.561,0:00:12.745
situated on the southeastern tip of Long Island

0:00:12.745,0:00:15.910
near the town of Southampton in New York.

0:00:15.910,0:00:18.380
When I was a little girl,

0:00:18.380,0:00:23.728
my grandfather took me to sit outside in the sun on a hot summer day.

0:00:23.728,0:00:27.282
There were no clouds in the sky.

0:00:27.282,0:00:30.453
And after a while I began to perspire.

0:00:30.453,0:00:33.979
And he pointed up to the sky, and he said,

0:00:33.979,0:00:36.827
"Look, do you see that?

0:00:36.827,0:00:38.946
That's part of you up there.

0:00:38.946,0:00:41.861
That's your water that helps to make the cloud

0:00:41.861,0:00:46.134
that becomes the rain that feeds the plants

0:00:46.134,0:00:49.920
that feeds the animals."

0:00:49.920,0:00:52.912
In my continued exploration of subjects in nature

0:00:52.912,0:00:57.328
that have the ability to illustrate the interconnection of all life,

0:00:57.328,0:01:00.029
I started storm chasing in 2008

0:01:00.029,0:01:03.897
after my daughter said, "Mom, you should do that."

0:01:03.897,0:01:10.108
And so three days later, driving very fast,

0:01:10.108,0:01:17.368
I found myself stalking a single type of giant cloud called the super cell,

0:01:17.368,0:01:21.819
capable of producing grapefruit-size hail

0:01:21.819,0:01:23.812
and spectacular tornadoes,

0:01:23.812,0:01:30.118
although only two percent actually do.

0:01:30.118,0:01:35.262
These clouds can grow so big, up to 50 miles wide

0:01:35.262,0:01:39.328
and reach up to 65,000 feet into the atmosphere.

0:01:39.328,0:01:41.702
They can grow so big, blocking all daylight,

0:01:41.702,0:01:46.826
making it very dark and ominous standing under them.

0:01:46.826,0:01:49.728
Storm chasing is a very tactile experience.

0:01:49.728,0:01:53.995
There's a warm, moist wind blowing at your back

0:01:53.995,0:02:00.697
and the smell of the earth, the wheat, the grass, the charged particles.

0:02:00.697,0:02:04.094
And then there are the colors in the clouds

0:02:04.094,0:02:09.284
of hail forming, the greens and the turquoise blues.

0:02:09.284,0:02:12.562
I've learned to respect the lightning.

0:02:12.562,0:02:14.696
My hair used to be straight.

0:02:14.696,0:02:16.120
(Laughter)

0:02:16.120,0:02:17.744
I'm just kidding.

0:02:17.744,0:02:19.886
(Laughter)

0:02:19.886,0:02:23.062
What really excites me about these storms

0:02:23.062,0:02:27.279
is their movement, the way they swirl and spin and undulate,

0:02:27.279,0:02:31.297
with their lava lamp-like mammatus clouds.

0:02:31.297,0:02:34.029
They become lovely monsters.

0:02:34.029,0:02:36.562
When I'm photographing them,

0:02:36.562,0:02:40.295
I cannot help but remember my grandfather's lesson.

0:02:40.295,0:02:42.287
As I stand under them,

0:02:42.287,0:02:44.494
I see not just a cloud,

0:02:44.494,0:02:47.377
but understand that what I have the privilege to witness

0:02:47.377,0:02:51.827
is the same forces, the same process in a small-scale version

0:02:51.827,0:02:58.145
that helped to create our galaxy, our solar system, our sun

0:02:58.145,0:03:02.703
and even this very planet.

0:03:02.703,0:03:05.160
All my relations. Thank you.

0:03:05.160,0:03:07.537
(Applause)
