the Dust Bowl, a man made disaster by me.
- 00:05 - 00:07
The environment before the Dust Bowl,
- 00:07 - 00:12
there was no deep rooted grasses and there was nothing to hold eroding soil in place.
- 00:12 - 00:15
That caused all of the soil
- 00:15 - 00:17
to blow up into the air
- 00:18 - 00:22
and start what is now known as the Dust Bowl.
- 00:23 - 00:24
But
- 00:26 - 00:27
after the dust real
- 00:28 - 00:33
after the dust will, almost all of the farmland was useless.
- 00:33 - 00:40
35 million acres to be exact, could not be farmed on or used for nine years.
- 00:41 - 00:44
After those nine years, rainfall came back to normal
- 00:44 - 00:48
and things started to progress like they used to
- 00:51 - 00:52
what caused
- 00:52 - 00:55
how we humans caused the Dust Bowl.
- 00:56 - 00:59
The Dust Bowl was caused by multiple effects such as
- 00:59 - 01:01
poor and aggressive farming
- 01:01 - 01:02
practices
- 01:02 - 01:03
and other
- 01:03 - 01:07
factors that caused it was very dry conditions and high winds.
- 01:07 - 01:10
The farming practices were poorly done
- 01:10 - 01:13
and since there was no deep rooted soil,
- 01:13 - 01:16
it pushed all of the wind in the air and there was no
- 01:16 - 01:21
tree rose at the time to prevent that and protect us from that.
- 01:21 - 01:26
So a lot of dust got kicked up into the air and caused a lot of problems.
- 01:29 - 01:31
The effects the effects
- 01:31 - 01:32
that the
- 01:32 - 01:37
um Dust bowl had on the environment where geochemical cycles,
- 01:37 - 01:41
the loss of all of our water and the wind kicking up dust.
- 01:41 - 01:45
It also affected our water cycle because after the dust bowl,
- 01:45 - 01:49
there was little to no precipitation in the air for nine years,
- 01:52 - 01:52
food webs,
- 01:53 - 01:55
the Dust bowl affected our food webs
- 01:55 - 01:58
because our primary producers were all destroyed.
- 01:58 - 02:02
This affect land animals not being able to survive from lack of food
- 02:02 - 02:05
because the primary producers could not
- 02:05 - 02:10
help the primary consumers get the energy they needed and so on and so forth.
- 02:10 - 02:12
No animals could get the food they needed,
- 02:16 - 02:17
prevention,
- 02:17 - 02:19
multiple things we can do to prevent dust balls
- 02:20 - 02:23
like increase our organic matter
- 02:23 - 02:24
windbreaks
- 02:24 - 02:25
like tree rows
- 02:26 - 02:28
to prevent wind from blowing up
- 02:28 - 02:29
soil.
- 02:30 - 02:33
No farmer telling no till farming is growing
- 02:33 - 02:36
crops from year to year without distributing soil
- 02:36 - 02:39
by tillage, spreading crop residue and the fall
- 02:40 - 02:43
can provide a base of cover for ground over winter.
- 02:45 - 02:48
My scientific evidence are
- 02:48 - 02:52
the first one shows the levels of precipitation we had before and
- 02:52 - 02:54
after the dust bowl. Before
- 02:54 - 02:56
there was not much
- 02:56 - 03:02
or before. There was a lot and good normal amounts of precipitation, but afterwards
- 03:02 - 03:05
after it slowly decreased,
- 03:05 - 03:08
it took a very very slow increase because the
- 03:08 - 03:11
dust bowl get took away lots of our precipitation.
- 03:11 - 03:13
The next one shows how
- 03:14 - 03:18
the levels of the dust bowl went from very bad in the middle and slowly got out.
- 03:19 - 03:19
This,
- 03:19 - 03:23
this shows where most of the farming and poor tillage or
- 03:23 - 03:28
poor farming practices took place and where the wind cooked up.
- 03:30 - 03:30
Yeah,
- 03:31 - 03:33
how to how to fix the dust bowl.
- 03:33 - 03:40
Um My short term fix that they had was during the dust bowl. The residents would
- 03:40 - 03:44
in the overlapping area hung wet sheets and the doorways and windows
- 03:44 - 03:47
to make sure dust wouldn't get through to protect to protect themselves from
- 03:48 - 03:48
um
- 03:49 - 03:51
um Dust Bowl pneumonia.
- 03:51 - 03:56
And so they would not get sick or so they could protect themselves.
- 03:57 - 03:59
Pro post hospital.
- 03:59 - 04:01
We came up with a solution to prevent it,
- 04:01 - 04:05
called soil erosion service and the Prairie States Forestry Project.
- 04:05 - 04:06
In 1935
- 04:07 - 04:10
these farmers had to plant trees is windbreaks on farms.
- 04:10 - 04:14
These windbreaks were huge rows of trees that
- 04:14 - 04:17
would protect crops from blowing up wind.
- 04:17 - 04:20
And these trees protected us from strong winds
- 04:20 - 04:22
and stopping the Dust Bowl from happening again.
- 04:22 - 04:24
And so far it works pretty well.
- 04:27 - 04:29
The impact the dust pull affected
- 04:31 - 04:36
Millions of people. 2.5 million people had to leave the area
- 04:36 - 04:37
and
- 04:37 - 04:39
the people who stayed claimed that
- 04:40 - 04:41
most lives,
- 04:42 - 04:46
it claimed most lives killed a lot of people from the new disease called
- 04:46 - 04:48
Dust Bowl pneumonia.
- 04:48 - 04:51
This led to an increased hospital admissions
- 04:51 - 04:53
to a higher risk of premature death,
- 04:53 - 04:57
primarily due to cardiovascular and respiratory disorders,
- 04:57 - 05:00
from inhaling lots and lots of dust and dirt.
- 05:02 - 05:05
Lastly, here are my sources.
- 05:05 - 05:11
There's all of those and that was my presentation. I hope you enjoyed it.
