No so we finally arrived at the day you've all

00:05

been waiting for our first lesson on the history of

00:08

agriculture Wait for that Well sorry we'll give you a

00:12

second switch gears there before we get into any of

00:15

the fun stuff we're gonna dip into some science first

00:17

growing enough food to feed seven billion people isn't a

00:21

simple process Farming is a little bit more complicated than

00:24

sticking a potato in the ground and hoping it'll grow

00:26

into a no potato tree Also please don't do that

00:30

and please be smarter than that So farming is a

00:33

crazy dance involving soil quality the type of crop planted

00:38

weather human labor machines on the market place that we're

00:42

up to us We'd still be living off blackberries and

00:45

random dead animals were found in the woods Actually our

00:48

ancestors were a whole lot smarter than we are when

00:51

it came to settling down and living off the land

00:53

Let's start with understanding dirt Who dirt This video is

00:57

going to be a thrill a minute But after all

00:59

that's where the food comes from well dirt is actually

01:02

a combination of sand clay and hamas that's organic matter

01:06

Not tasty middle eastern being spread so don't go dipping

01:09

pita bread in a freshly killed field it's weird That

01:12

phrase poor as dirt is actually a phrase because during

01:15

is actually rich with everything we need to survive It's

01:19

full of different combinations of chemicals minerals and microscopic critters

01:23

Dirt's composition varies depending on where we go because many

01:27

different factors influence the composition of soil Here are a

01:30

few of the key factors One thing that's finds a

01:33

type of dirt is the rock it came from Most

01:36

soil is just decomposing organic matter but some of it

01:40

isn't Some of it is rock that's Uh having a

01:43

total breakdown that is is breaking down into tiny minerals

01:47

I can't speak for its emotional like weather also has

01:51

a huge effect on soil wind rain snow ice and

01:54

son can all change the kind of soil we end

01:57

up with and dry areas wind can blow dirt this

02:01

way and that in other areas acid rain might change

02:04

the chemical composition of dirt All of this changes the

02:07

way dirt turns out well different types of plants and

02:10

animals will change the kind of soil we get part

02:12

of the soil is made up of their decomposed bodies

02:16

except the ones that become zombies used died Of course

02:19

well plants also have the skills to enrich soil by

02:22

pulling up nutrients from deeper down and bringing them in

02:25

from the top Also we have fungi and bacteria which

02:30

eat tiny things in the soil and turn them into

02:32

other tiny things that are good for plants Yes simba

02:36

it's the circle of life plain old time is a

02:39

huge factor as well Everything takes time right and just

02:43

like you can't hurry love no you just have to

02:45

wait You also can't hurry dirt Longer jerk has been

02:49

around the more it had to be influenced by decomposing

02:52

bacteria and badgers and stuff If decomposing badgers are more

02:57

influential and most of it don't start their badgers No
