0:00:01.015,0:00:04.008
This story starts with these two --

0:00:04.032,0:00:05.290
my kids.

0:00:05.314,0:00:06.996
We were hiking in the Oakland woods

0:00:07.020,0:00:11.154
when my daughter noticed[br]a plastic tub of cat litter in a creek.

0:00:11.647,0:00:13.309
She looked at me and said,

0:00:13.333,0:00:15.840
"Daddy?

0:00:15.864,0:00:17.514
That doesn't go there."

0:00:17.538,0:00:19.960
When she said that,[br]it reminded me of summer camp.

0:00:19.984,0:00:21.482
On the morning of visiting day,

0:00:21.506,0:00:25.169
right before they'd let our anxious[br]parents come barreling through the gates,

0:00:25.193,0:00:26.562
our camp director would say,

0:00:26.586,0:00:28.895
"Quick! Everyone pick up[br]five pieces of litter."

0:00:28.919,0:00:31.959
You get a couple hundred kids[br]each picking up five pieces,

0:00:31.983,0:00:34.556
and pretty soon, you've got[br]a much cleaner camp.

0:00:34.580,0:00:35.739
So I thought,

0:00:35.763,0:00:40.300
why not apply that crowdsourced[br]cleanup model to the entire planet?

0:00:40.324,0:00:43.275
And that was the inspiration[br]for Litterati.

0:00:43.299,0:00:46.648
The vision is to create[br]a litter-free world.

0:00:46.672,0:00:48.180
Let me show you how it started.

0:00:48.204,0:00:51.590
I took a picture of a cigarette[br]using Instagram.

0:00:52.222,0:00:54.089
Then I took another photo ...

0:00:54.113,0:00:55.670
and another photo ...

0:00:55.694,0:00:56.861
and another photo.

0:00:56.885,0:00:58.171
And I noticed two things:

0:00:58.195,0:01:01.667
one, litter became artistic[br]and approachable;

0:01:02.244,0:01:03.395
and two,

0:01:03.419,0:01:05.934
at the end of a few days,[br]I had 50 photos on my phone

0:01:05.958,0:01:07.545
and I had picked up each piece,

0:01:07.569,0:01:09.954
and I realized that I was keeping a record

0:01:09.978,0:01:13.129
of the positive impact[br]I was having on the planet.

0:01:13.153,0:01:15.341
That's 50 less things that you might see,

0:01:15.365,0:01:16.608
or you might step on,

0:01:16.632,0:01:18.090
or some bird might eat.

0:01:18.769,0:01:21.421
So I started telling people[br]what I was doing,

0:01:21.445,0:01:23.801
and they started participating.

0:01:24.831,0:01:26.524
One day,

0:01:26.548,0:01:29.076
this photo showed up from China.

0:01:30.039,0:01:31.310
And that's when I realized

0:01:31.334,0:01:34.600
that Litterati was more[br]than just pretty pictures;

0:01:34.624,0:01:37.993
we were becoming a community[br]that was collecting data.

0:01:38.869,0:01:40.759
Each photo tells a story.

0:01:41.279,0:01:43.472
It tells us who picked up what,

0:01:43.496,0:01:45.507
a geotag tells us where

0:01:45.531,0:01:47.561
and a time stamp tells us when.

0:01:48.006,0:01:50.435
So I built a Google map,

0:01:50.459,0:01:54.512
and started plotting the points[br]where pieces were being picked up.

0:01:54.536,0:01:58.454
And through that process,[br]the community grew

0:01:58.478,0:02:00.117
and the data grew.

0:02:00.806,0:02:04.267
My two kids go to school[br]right in that bullseye.

0:02:05.125,0:02:06.336
Litter:

0:02:06.360,0:02:09.064
it's blending into[br]the background of our lives.

0:02:09.088,0:02:11.187
But what if we brought it[br]to the forefront?

0:02:11.211,0:02:14.123
What if we understood exactly[br]what was on our streets,

0:02:14.147,0:02:15.536
our sidewalks

0:02:15.560,0:02:17.098
and our school yards?

0:02:17.122,0:02:20.369
How might we use that data[br]to make a difference?

0:02:21.189,0:02:22.387
Well, let me show you.

0:02:22.411,0:02:23.796
The first is with cities.

0:02:24.418,0:02:29.057
San Francisco wanted to understand[br]what percentage of litter was cigarettes.

0:02:29.081,0:02:30.243
Why?

0:02:30.267,0:02:31.476
To create a tax.

0:02:32.073,0:02:34.208
So they put a couple of people[br]in the streets

0:02:34.232,0:02:35.593
with pencils and clipboards,

0:02:35.617,0:02:37.680
who walked around collecting information

0:02:37.704,0:02:40.815
which led to a 20-cent tax[br]on all cigarette sales.

0:02:41.787,0:02:43.940
And then they got sued

0:02:43.964,0:02:45.140
by big tobacco,

0:02:45.164,0:02:48.380
who claimed that collecting information[br]with pencils and clipboards

0:02:48.404,0:02:50.735
is neither precise nor provable.

0:02:51.454,0:02:55.134
The city called me and asked[br]if our technology could help.

0:02:55.158,0:02:56.407
I'm not sure they realized

0:02:56.431,0:02:58.679
that our technology[br]was my Instagram account --

0:02:58.703,0:02:59.742
(Laughter)

0:02:59.766,0:03:01.032
But I said, "Yes, we can."

0:03:01.056,0:03:02.072
(Laughter)

0:03:02.096,0:03:06.004
"And we can tell you[br]if that's a Parliament or a Pall Mall.

0:03:06.028,0:03:09.453
Plus, every photograph[br]is geotagged and time-stamped,

0:03:09.477,0:03:10.858
providing you with proof."

0:03:11.839,0:03:15.059
Four days and 5,000 pieces later,

0:03:15.083,0:03:20.021
our data was used in court[br]to not only defend but double the tax,

0:03:20.045,0:03:24.368
generating an annual recurring revenue[br]of four million dollars

0:03:24.392,0:03:26.687
for San Francisco to clean itself up.

0:03:28.001,0:03:30.236
Now, during that process[br]I learned two things:

0:03:30.260,0:03:32.814
one, Instagram is not the right tool --

0:03:32.838,0:03:33.869
(Laughter)

0:03:33.893,0:03:35.396
so we built an app.

0:03:35.420,0:03:37.053
And two, if you think about it,

0:03:37.077,0:03:40.694
every city in the world[br]has a unique litter fingerprint,

0:03:40.718,0:03:44.554
and that fingerprint provides[br]both the source of the problem

0:03:44.578,0:03:46.499
and the path to the solution.

0:03:47.646,0:03:50.024
If you could generate a revenue stream

0:03:50.048,0:03:52.511
just by understanding[br]the percentage of cigarettes,

0:03:52.535,0:03:54.631
well, what about coffee cups

0:03:54.655,0:03:56.361
or soda cans

0:03:56.385,0:03:57.799
or plastic bottles?

0:03:58.501,0:04:01.702
If you could fingerprint San Francisco,[br]well, how about Oakland

0:04:01.726,0:04:03.422
or Amsterdam

0:04:03.446,0:04:06.416
or somewhere much closer to home?

0:04:07.408,0:04:08.642
And what about brands?

0:04:08.666,0:04:10.567
How might they use this data

0:04:10.591,0:04:14.803
to align their environmental[br]and economic interests?

0:04:15.646,0:04:18.858
There's a block in downtown Oakland[br]that's covered in blight.

0:04:19.325,0:04:23.429
The Litterati community got together[br]and picked up 1,500 pieces.

0:04:23.812,0:04:25.152
And here's what we learned:

0:04:25.176,0:04:28.386
most of that litter came[br]from a very well-known taco brand.

0:04:29.738,0:04:33.315
Most of that brand's litter[br]were their own hot sauce packets,

0:04:34.438,0:04:38.064
and most of those hot sauce packets[br]hadn't even been opened.

0:04:39.965,0:04:42.680
The problem and the path[br]to the solution --

0:04:42.704,0:04:46.665
well, maybe that brand only[br]gives out hot sauce upon request

0:04:46.689,0:04:48.698
or installs bulk dispensers

0:04:48.722,0:04:51.274
or comes up with more[br]sustainable packaging.

0:04:51.298,0:04:54.267
How does a brand take[br]an environmental hazard,

0:04:54.291,0:04:56.297
turn it into an economic engine

0:04:56.321,0:04:58.089
and become an industry hero?

0:04:59.292,0:05:01.494
If you really want to create change,

0:05:01.518,0:05:04.392
there's no better place to start[br]than with our kids.

0:05:04.416,0:05:07.819
A group of fifth graders picked up[br]1,247 pieces of litter

0:05:07.843,0:05:09.691
just on their school yard.

0:05:09.715,0:05:12.247
And they learned that the most[br]common type of litter

0:05:12.271,0:05:15.505
were the plastic straw wrappers[br]from their own cafeteria.

0:05:15.947,0:05:18.476
So these kids went[br]to their principal and asked,

0:05:18.500,0:05:20.160
"Why are we still buying straws?"

0:05:21.166,0:05:22.921
And they stopped.

0:05:22.945,0:05:26.599
And they learned that individually[br]they could each make a difference,

0:05:26.623,0:05:28.961
but together they created an impact.

0:05:29.503,0:05:33.515
It doesn't matter[br]if you're a student or a scientist,

0:05:33.539,0:05:36.674
whether you live in Honolulu or Hanoi,

0:05:36.698,0:05:39.139
this is a community for everyone.

0:05:39.974,0:05:44.653
It started because of two little kids[br]in the Northern California woods,

0:05:44.677,0:05:47.491
and today it's spread across the world.

0:05:47.938,0:05:49.721
And you know how we're getting there?

0:05:50.067,0:05:51.945
One piece at a time.

0:05:52.508,0:05:53.723
Thank you.

0:05:53.747,0:05:57.365
(Applause)
