and President Theodore Roosevelt

needed a little break from the White House,

so he took a train to Mississippi

to do a little black bear hunting outside of a town

called Smedes.

The first day of the hunt, they didn't see a single bear,

so it was a big bummer for everyone,

but the second day, the dogs cornered one

after a really long chase, but by that point,

the president had given up

and gone back to camp for lunch,

so his hunting guide cracked the animal

on the top of the head with the butt of his rifle,

and then tied it up to a tree

and started tooting away on his bugle

to call Roosevelt back so he could have the honor

of shooting it.

The bear was a female.

It was dazed, injured,

severely underweight, a little mangy-looking,

and when Roosevelt saw this animal

tied up to the tree,

he just couldn't bring himself to fire at it.

He felt like that would go against his code

as a sportsman.

A few days later, the scene was memorialized

in a political cartoon back in Washington.

It was called "Drawing a Line in Mississippi,"

and it showed Roosevelt with his gun down and his arm out,

sparing the bear's life,

and the bear was sitting on its hind legs

with these two big, frightened, wide eyes

and little ears pricked up at the top of its head.

It looked really helpless, like you just wanted to

sweep it up into your arms

and reassure it.

It wouldn't have looked familiar at the time,

but if you go looking for the cartoon now,

you recognize the animal right away:

It's a teddy bear.

And this is how the teddy bear was born.

Essentially, toymakers took the bear from the cartoon,

turned it into a plush toy, and then named it

after President Roosevelt -- Teddy's bear.

And I do feel a little ridiculous

that I'm up here on this stage

and I'm choosing to use my time

to tell you about a 100-year-old story

about the invention of a squishy kid's toy,

but I'd argue that the invention of the teddy bear,

inside that story is a more important story,

a story about how dramatically our ideas

about nature can change,

and also about how, on the planet right now,

the stories that we tell

are dramatically changing nature.

Because think about the teddy bear.

For us, in retrospect, it feels like an obvious fit,

because bears are so cute and cuddly,

and who wouldn't want to give one to their kids to play with,

but the truth is that in 1902,

bears weren't cute and cuddly.

I mean, they looked the same,

but no one thought of them that way.

In 1902, bears were monsters.

Bears were something that frickin' terrified kids.

For generations at that point,

the bear had been a shorthand for all the danger

that people were encountering on the frontier,

and the federal government was actually

systematically exterminating bears

and lots of other predators too,

like coyotes and wolves.

These animals, they were being demonized.

They were called murderers

because they killed people's livestock.

One government biologist, he explained this

war on animals like the bear by saying

that they no longer had a place

in our advancing civilization,

and so we were just clearing them out of the way.

In one 10-year period, close to half a million wolves

had been slaughtered.

The grizzly would soon be wiped out

from 95 percent of its original territory,

and whereas once there had been 30 million bison

moving across the plains, and you would have

these stories of trains having to stop

for four or five hours so that these thick,

living rivers of the animals could pour over the tracks,

now, by 1902, there were maybe less than 100 left in the wild.

And so what I'm saying is, the teddy bear was born

into the middle of this great spasm of extermination,

and you can see it as a sign that

maybe some people deep down

were starting to feel conflicted about all that killing.

America still hated the bear and feared it,

but all of a sudden, America also wanted

to give the bear a great big hug.

So this is something that I've been really curious about in the last few years.

How do we imagine animals,

how do we think and feel about them,

and how do their reputations get written

and then rewritten in our minds?

We're here living in the eye of a great storm

of extinction where half the species on the planet

could be gone by the end of the century,

and so why is it that we come to care about

some of those species and not others?

Well, there's a new field, a relatively new field

of social science that started looking at

these questions and trying to unpack the powerful

and sometimes pretty schizophrenic relationships

that we have to animals,

and I spent a lot of time looking through

their academic journals,

and all I can really say is that their findings

are astonishingly wide-ranging.

So some of my favorites include that

the more television a person watches in Upstate New York,

the more he or she is afraid

of being attacked by a black bear.

If you show a tiger to an American,

they're much more likely to assume that it's female

and not male.

In a study where a fake snake

and a fake turtle were put on the side of the road,

drivers hit the snake much more often than the turtle,

and about three percent of drivers who hit the fake animals

seemed to do it on purpose.

Women are more likely than men to get a

"magical feeling" when they see dolphins in the surf.

Sixty-eight percent of mothers with

"high feelings of entitlement and self-esteem"

identified with the dancing cats

in a commercial for Purina. (Laughter)

Americans consider lobsters

more important than pigeons

but also much, much stupider.

Wild turkeys are seen as only slightly more dangerous than sea otters,

and pandas are twice as lovable as ladybugs.

So some of this is physical, right?

We tend to sympathize more with animals that look like us,

and especially that resemble human babies,

so with big, forward-facing eyes

and circular faces,

kind of a roly-poly posture.

This is why, if you get a Christmas card from, like,

your great aunt in Minnesota,

there's usually a fuzzy penguin chick on it,

and not something like a Glacier Bay wolf spider.

But it's not all physical, right?

There's a cultural dimension to how we think about animals,

and we're telling stories about these animals,

and like all stories,

they are shaped by the times and the places

in which we're telling them.

So think about that moment

back in 1902 again where a ferocious bear

became a teddy bear.

What was the context? Well, America was urbanizing.

For the first time, nearly a majority of people lived in cities,

so there was a growing distance between us and nature.

There was a safe space where we could

reconsider the bear and romanticize it.

Nature could only start to seem this pure and adorable

because we didn't have to be afraid of it anymore.

And you can see that cycle playing out

again and again with all kinds of animals.

It seems like we're always stuck between

demonizing a species and wanting to wipe it out,

and then when we get very close to doing that,

empathizing with it as an underdog

and wanting to show it compassion.

So we exert our power,

but then we're unsettled

by how powerful we are.

So for example, this is one of

probably thousands of letters and drawings

that kids sent to the Bush administration,

begging it to protect the polar bear

under the Endangered Species Act,

and these were sent back in the mid-2000s,

when awareness of climate change was suddenly surging.

We kept seeing that image of a polar bear

stranded on a little ice floe

looking really morose.

I spent days looking through these files.

I really love them. This one's my favorite.

If you can see, it's a polar bear that's drowning

and then it's also being eaten simultaneously

by a lobster and a shark.

This one came from a kid named Fritz,

and he's actually got a solution to climate change.

He's got it all worked out to an ethanol-based solution.

He says, "I feel bad about the polar bears.

I like polar bears.

Everyone can use corn juice for cars. From Fritz."

So 200 years ago, you would have Arctic explorers

writing about polar bears leaping into their boats

and trying to devour them,

even if they lit the bear on fire,

but these kids don't see the polar bear that way,

and actually they don't even see the polar bear

the way that I did back in the '80s.

I mean, we thought of these animals

as mysterious and terrifying lords of the Arctic.

But look now how quickly that climate change

has flipped the image of the animal in our minds.

It's gone from that bloodthirsty man-killer

to this delicate, drowning victim,

and when you think about it, that's kind of

the conclusion to the story

that the teddy bear started telling back in 1902,

because back then, America had more or less

conquered its share of the continent.

We were just getting around to

polishing off these last wild predators.

Now, society's reach has expanded

all the way to the top of the world,

and it's made even these, the most remote,

the most powerful bears on the planet,

seem like adorable and blameless victims.

But you know, there's also a postscript to the teddy bear story

that not a lot of people talk about.

We're going to talk about it,

because even though it didn't really take long

after Roosevelt's hunt in 1902

for the toy to become a full-blown craze,

most people figured it was a fad,

it was a sort of silly political novelty item

and it would go away once the president left office,

and so by 1909, when Roosevelt's successor,

William Howard Taft,

was getting ready to be inaugurated,

the toy industry was on the hunt

for the next big thing.

They didn't do too well.

That January, Taft was the guest of honor

at a banquet in Atlanta,

and for days in advance,

the big news was the menu.

They were going to be serving him

a Southern specialty, a delicacy, really,

called possum and taters.

So you would have a whole opossum

roasted on a bed of sweet potatoes,

and then sometimes they'd leave

the big tail on it like a big, meaty noodle.

The one brought to Taft's table

weighed 18 pounds.
