about some of my discoveries

around the world through my work.

These are not discoveries of planets

or new technologies

or science.

They're discoveries of people

and the way people are, and new leadership.

This is Benki.

Benki is a leader of the Ashaninka Nation.

His people live in Brazil

and in Peru.

Benki comes from a village

so remote up in the Amazon

that to get there, either you have to fly

and land on water,

or go by canoe for several days.

I met Benki three years ago in Sao Paulo

when I'd brought him and other leaders

from indigenous peoples

to meet with me and leaders from around the world,

because we wanted to learn from each other.

We wanted to share our stories with each other.

The Ashaninka people

are known throughout South America

for their dignity, their spirit

and their resistance,

starting with the Incas

and continuing through the 19th century

with the rubber tappers.

Today's biggest threat to the Ashaninka people

and to Benki

comes from illegal logging --

the people who come into the beautiful forest

and cut down ancient mahogany trees,

float them down the river to world markets.

Benki knew this.

He could see what was happening to his forest, to his environment,

because he was taken under his grandfather's wing

when he was only two years old

to begin to learn about the forest

and the way of life of his people.

His grandfather died when he was only 10.

And at that young age, 10 years old,

Benki became the paje of his community.

Now, in the Ashaninka tradition and culture,

the paje is the most important

person in the community.

This is the person who contains within him

all the knowledge, all the wisdom

of centuries and centuries of life,

and not just about his people,

but about everything that his people's survival depended on:

the trees, the birds,

the water, the soil, the forest.

So when he was only 10 and he became the paje,

he began to lead his people.

He began to talk to them

about the forest that they needed to protect,

the way of life they needed to nurture.

He explained to them

that it was not a question of survival of the fittest;

it was a question of understanding

what they needed to survive

and to protect that.

Eight years later,

when he was a young man of 18,

Benki left the forest for the first time.

He went 3,000 miles on an odyssey to Rio

to the Earth Summit

to tell the world what was happening

in his tiny, little corner.

And he went because he hoped the world would listen.

Some did, not everybody.

But if you can imagine this young man

with his headdress and his flowing robe,

learning a new language, Portuguese,

not to mention English,

going to Rio,

building a bridge

to reach out to people he'd never met before --

a pretty hostile world.

But he wasn't dismayed.

Benki came back to his village full of ideas --

new technologies, new research,

new ways of understanding what was going on.

Since that time,

he's continued to work with his people,

and not only the Ashaninka Nation,

but all the peoples of the Amazon and beyond.

He's built schools

to teach children to care for the forest.

Together, he's led the reforestation

of over 25 percent of the land

that had been destroyed by the loggers.

He's created a cooperative

to help people diversify their livelihoods.

And he's brought the internet and satellite technology

to the forest --

both so that people themselves

could monitor the deforestation,

but also that he could speak from the forest

to the rest of the world.

If you were to meet Benki

and ask him, "Why are you doing this?

Why are you putting yourself at risk?

Why are you making yourself vulnerable

to what is often a hostile world?"

he would tell you,

as he told me,

"I asked myself," he said,

"What did my grandparents and my great-grandparents do

to protect the forest for me?

And what am I doing?"

So when I think of that,

I wonder what our grandchildren

and our great-grandchildren,

when they ask themselves that question,

I wonder how they will answer.

For me, the world is veering

towards a future we don't much want

when we really think about it deep inside.

It's a future we don't know the details of,

but it's a future that has signs,

just like Benki saw the signs around him.

We know we are running out of what we need.

We're running out of fresh water.

We're running out of fossil fuels.

We're running out of land.

We know climate change is going to affect all of us.

We don't know how, but we know it will.

And we know that there will be more of us than ever before --

five times as many people in 40 years

than 60 years ago.

We are running out of what we need.

And we also know

that the world has changed in other ways,

that since 1960

there are one-third as many new countries

that exist as independent entities on the planet.

Egos, systems of government --

figuring it out --

massive change.

And in addition to that,

we know that five other really big countries

are going to have a say in the future,

a say we haven't even really started to hear yet --

China, India,

Russia, South Africa

and Benki's own Brazil,

where Benki got his civil rights

only in the 1988 constitution.

But you know all that.

You know more than Benki knew when he left his forest

and went 3,000 miles.

You also know

that we can't just keep doing what we've always done,

because we'll get the results

we've always gotten.

And this reminds me of something I understand

Lord Salisbury said to Queen Victoria over a hundred years ago,

when she was pressing him, "Please change."

He said, "Change?

Why change?

Things are bad enough as they are."

We have to change.

It's imperative to me, when I look around the world,

that we need to change ourselves.

We need new models of what it means to be a leader.

We need new models

of being a leader and a human in the world.

I started life as a banker.

Now I don't admit to that

to anybody but my very close friends.

But for the past eight years,

I've done something completely different.

My work has taken me around the world,

where I've had the real privilege

of meeting people like Benki

and many others who are making change happen

in their communities --

people who see the world differently,

who are asking different questions,

who have different answers,

who understand the filters that they wear

when they go out into the world.

This is Sanghamitra.

Sanghamitra comes from Bangalore.

I met Sanghamitra eight years ago

when I was in Bangalore

organizing a workshop with leaders of different NGO's

working in some of the hardest aspects of society.

Sanghamitra didn't start life

as a leader of an NGO,

she started her career as university professor,

teaching English literature.

But she realized that she was much too detached from the world doing that.

She loved it, but she was too detached.

And so in 1993,

a long time ago,

she decided to start a new organization

called Samraksha

focused on one of the hardest areas,

one of the hardest issues in India --

anywhere in the world at the time --

HIV/AIDS.

Since that time, Samraksha has grown

from strength to strength

and is now one of the leading health NGO's in India.

But if you just think about the state of the world

and knowledge of HIV/AIDS

in 1993 --

in India at that time it was skyrocketing

and nobody understood why,

and everyone was actually very, very afraid.

Today there are still three million

HIV-positive people in India.

That's the second largest population in the world.

When I asked Sanghamitra,

"How did you get from English literature

to HIV/AIDS?"

not an obvious path,

she said to me,

"It's all connected.

Literature makes one sensitive,

sensitive to people,

to their dreams and to their ideas."

Since that time, under her leadership,

Samraksha has been a pioneer

in all fields related

to HIV/AIDS.

They have respite homes, the first,

the first care centers,

the first counseling services --

and not just in urban, 7-million-population Bangalore,

but in the hardest to reach villages

in the state of Karnataka.

Even that wasn't enough.

She wanted to change policy at the government level.

10 of their programs that she pioneered

are now government policy and funded by the government.

They take care of 20,000-odd people today

in over 1,000 villages around Karnataka.

She works with people like Murali Krishna.

Murali Krishna comes from one of those villages.

He lost his wife to AIDS a couple of years ago,

and he's HIV-positive.

But he saw the work, the care,

the compassion

that Sanghamitra and her team brought to the village,

and he wanted to be part of it.

He's a Leaders' Quest fellow, and that helps him with his work.

They've pioneered a different approach to villages.

Instead of handing out information in pamphlets,

as is so often the case,

they bring theater troupes,

songs, music, dance.

And they sit around,

and they talk about dreams.

Sanghamitra told me just last week --

she had just come back from two weeks in the villages,

and she had a real breakthrough.

They were sitting in a circle, talking about the dreams for the village.

And the young women in the village
