Over the past 200 years the world’s population has increased from 1.6 billion to 7.6 billion.
This has affected agriculture, because we have had to break down buildings for crop areas.
By the year 2050 the world’s population is going to be 9 billion, the food production is
expected to raise by 60%. To improve this problem we can build greenhouses on top of
buildings to make more room for crops. We can also clear out the old buildings that are no
longer in service, therefore there will be more room for harvesting. The worlds most harvesting
crop is wheat, with 211 million areas owned. If farmers aren’t growing wheat in the fall then
they are growing corn in the spring.
In 1793 it all started with an inventor named Eli Whitney, the cotton gin was a huge effect in the
South. Farmers could plant more cotton now that it was easier to clean, cotton soon became
the number one cash crop. When they needed more land to harvest farmers would take native
Americans land. The cotton gin affected the world, soon the north bought more cotton and
built textile mills. The South also did not have the need or the capital to build up a good
transportation system, such as canals and railroads. During the Civil War, the South had many
disadvantages over the North. A large portion of their population were uneducated slaves.
They had no factories to produce goods and to become self sufficient when they separated
from the North. Because the South had not built up a good transportation system, they were
not able to move men and supplies easily across the country, as the North was able to do. By
1860 cotton in the South has increased, the number of slaves in the United States had rapidly
increased. Capital had been invested in slaves, not in transportation or factories. All this
happened because of a very simple machine, the cotton gin. Now, almost every person has
clothing made of cotton. We just think of it as something we have and it will always be around.
Back when it was scarce people thought of it as something valuable. Although it wasn’t a cash
crop, it was still very useful and if they didn’t have it, then their everyday life would be
completely different.
John Deere invented the steel plow in 1837 when the Middle-West was being settled. Wood
plows couldn’t plow the rich soil of the Middle-West without breaking. John Deere thought
about it and was convinced that only a plow with mould board, made of good steel that isn’t
rusted would solve this problem. This affected America because in the first part of the 19th
century, the Western frontier was expanding and the population growing. American farmers
started looking for different plows that could withstand the plowing process without breaking,
and Deere provided them with his durable steel plow. Therefore, the demand for plows
increased quickly and Deere started producing more and more plows per year. Soon after,
most farmers were using plows, which increased efficiency to meet the demand of the people.
The steel plow impacted farm work, by increasing production and a reduction of labor force.
The plow did not cause a loss of many jobs, because normally farming was a family business,
ran by the farmer. Therefore, it benefited farmers because it enabled them to produce crops
that are more efficient in less time. Now, John Deere has many more inventions then just the
steel plow to help harvest crops. Many more people can buy these inventions, then it was a
limited supply now its an unlimited supply.
By 1900 the country’s total rail mileage had increased from 163,597 in 1890 to over 193,000
railroads in the 20th century. Railroading in the 1890s would see several East-West and NorthSouth
main lines in operation including no less than five routes connecting the West coast with
Midwest and Deep South. The railroad industry would see its record mileage in 1916 of
254,037 after that year mileage slowly declined and wouldn’t stop through the end of the
century. Also, the railroad industry’s “Golden Age”, or that time period when railroads were the
dominate mode of transportation, ended after roughly 1920 when other modes of travel began
to slowly entrench on the iron horse. To make matters worse, the greed and monopolist
practices of tycoons and railroad owners finally cost them as several new federal laws were
passed to reel in the industry. Unfortunately, this heavy regulation was not lifted until 1980 by
which time the industry had been mostly left for dead as an outdated mode of transportation.
Not only did freight yards jam and trains snarl to a crawl but many railroads simply did not
have enough locomotives and cars to weather the storm. Needing to keep traffic flowing for
the war effort the federal government stepped in and took over the industry in late December
of 1917. This effects the population because soon afterwards the people went to war and
couldn’t get their needs to them fast enough, therefore everybody in the war died over an
agricultural problem. Now, everybody uses trains to transport the items we need ex. Rocks,
soil, animals and much more.
