00:03

Okay, time for a whirlwind tour of the history of agriculture tech. [Tornado picks up a tractor]

00:07

It’ll be like a sharknado.

00:09

Only with farming implements instead of sharks. [A shark in the tornado]

00:13

A farmnado….

00:14

….Kinda glad that was never made into a TV movie.

00:18

We begin, as always, with the hunter-gatherers. [Hunter-gatherers appear out of the bushes]

00:20

Even though life was simple, humans were already starting to get technical.

00:24

No, it wasn’t exactly Silicon Valley, but we had to start somewhere. [Man sat using a laptop]

00:28

That "somewhere" was fishing.

00:30

Some of earliest peoples relied on fish for their food. [Man chucking a net into a lake]

00:34

So they developed nets and hooks to live the Long John Silver’s dream.

00:39

Later, in the Paleolithic period, folks got serious about chasing down big animals and [Man in a boxing ring with an mammoth]

00:45

eating them.

00:46

Wrestling a mammoth to the ground barehanded wasn’t such a great idea though. [Mammoth jumps on top of the man]

00:51

So early humans developed spears and arrows, which really did the trick.

00:56

Next, we move on to the Agricultural-Craftsman Era. [Man picking berries]

01:00

This is when humans decided it was time do some farming.

01:03

Going out into the woods and gathering every plant they wanted to eat was getting to be [Man planting bushes in a big hole]

01:08

a major drag.

01:10

One of the first key tools that humans developed to help in farming was the hoe.

01:14

Digging up a field barehanded was a guaranteed way to break a nail. [Man digging with his hands]

01:18

Along with hoe also came a primitive plow called an ard.

01:22

Plows steadily became more and more advanced.

01:24

And they became the key technology in agriculture for thousands of years. [Different plows talking to each other]

01:28

They changed over time, but all of them were crucial to food production in their day. [Plough goes along a field and crops appear behind it]

01:33

As soon as there were food surpluses, there had to be good ways of storing that extra

01:38

food.

01:39

Pottery, ceramics, and granaries were some of the early strategies of preserving food. [Mother looks angry as kid has eaten all the sugar]

01:44

What was the point is growing a bunch of food to just let it go bad?

01:48

Irrigation also became a big deal.

01:50

Places like India and China depended on complicated irrigation technologies to flood their rice [Man jumping in a wet field]

01:56

fields.

01:57

The rest of the world also needed to control and direct water.

02:00

Because sometimes Mother Nature just doesn’t want to cooperate. [Big wave]

02:03

She’s stubborn like that.

02:05

The Industrial Revolution changed everything, including agriculture. [Factories with big chimneys]

02:09

Reapers were some of the first machines to come onto the farm, and they reduced the amount [Modern harvesters driving on a field]

02:15

of human work a lot.

02:17

Soon, even more machines invaded the farm. [Machines appearing on a farm]

02:21

Threshers, combines, tractors, Transformers, robots in disguise…

02:26

These are the primary machines that switched farms from human and animal power to fossil [Man in a hammock]

02:31

fuel power.

02:32

Refrigeration was also huge, and changed the meat industry forever. [Truck with a lot of meat on the back]

02:36

Suddenly meat could be shipped over long distances, and livestock farms could be way bigger.

02:42

And how about good old-fashioned barbwire? [Cows crowded behind a fence]

02:44

At one time, it was actually new-fashioned, and it changed the meat industry.

02:49

Especially in the American West, barbed wire let the beef-ranching business boom. [Man with beef ranching industry flop shirt looks disappointed]

02:54

Once the Post-Industrial Era hit we still kept figuring out new stuff.

02:58

The Haber-Bosch process gave us the ability to make artificial fertilizer. [Scientist dancing on stage with people playing the guitar]

03:03

This was the single biggest event in the 20th century agricultural explosion called the

03:08

Green Revolution.

03:09

Pesticides and herbicides also came along. [Man chucking pesticide onto plants]

03:14

The ability to kill unwanted bugs and plants was a pretty big deal.

03:17

Fields could be bigger, and human labor could be reduced.

03:20

Recombinant DNA is the current big thing in agriculture.

03:23

This is the ability to mess with the DNA of plants and animals. [Scientist pouring liquid onto a plant which makes it grow sausages]

03:28

All to make those animals and plants more suited to being eaten human’s tastes. [Kid eating a hamburger]

03:34

Except for humans who shop at organic grocery stores, who do their best to reject every

03:38

development of the Post-Industrial Era. [Woman chooses organic produce over post-industrial produce]

03:41

The Post-Industrial Era must feel so rejected.
