You'd probably go out and forage for your food

foraging couldn't come near to providing enough food.

Farming, like what you see around me in this rice paddy

near Cheongju in South Korea, is absolutely essential

it may help to go back to the world of foragers.

Remember, foragers travel around their environments

and using them without processing them too much.

and they keep them in protected environments.

Now, we humans are not the only species that do this.

and in return, they get nutritious honeydew.

When species get dependent like this in the natural world,

over time they tend to change very, very rapidly indeed.

get so dependent on the aphids that if all the aphids died,

And the aphids get so dependent that they cannot reproduce

between species, such relations of close dependency,

But when humans are involved in such relations,

we tend to call it farming or agriculture.

When humans started farming, the species they tended to

the most nutritious wheat grains, or rice grains,

And the result was that within a few generations,

and they were created not by natural selection,

a modern corn cob, which is fat and nutritious and tasty,

which is a rather pathetic-looking, weedy plant.

domesticated sheep, which tends to be fat and docile

but they tended not to change genetically

so much as technologically, socially and culturally.

They learned to clear trees, to build paddy fields like this,

to divert rivers, to protect their crops and animals

And the result of all of this was that humans found

that they could produce more of what they wanted

than they had before and that meant that humans

But to get a real sense of what's going on with farming,

we need to think about it from a big history perspective.

Remember, all the energy that supports the biosphere,

into species that they could use and away from other species.

The result was a sort of huge energy grab

No wonder, with farming, human populations

So where and when did farming and agriculture begin?

At the moment, it looks as if farming really began

in the highlands east of the Mediterranean

It may also have grown... appeared at about the same time

in the Nile Valley, slightly further south.

we have evidence of rice growing in China

we have evidence of the growing of taro and yams
