The year is 2200 and the world has been officially declared as being devoid of all insect life. A combination of extreme climate change, chemical warfare and general environmental degradation has resulted in a mass die out of the entire insect population. Unsurprisingly this has had a major effect on all other forms of life ranging from aquatic to terrestrial. Some species have experienced a significant decline in population size and others have had to completely adapt new behaviors to survive. However, there are some that have largely benefitted from this insect free world. The die off of major disease vectors such as Anopheles, Aedes, and Culex mosquitoes which carry malaria, yellow fever, and zika had lead initially lead to increased health …show more content…
Agricultural products were no longer considered a potential source of carcinogens and other dangerous chemicals. The a number of wooded plants that weren’t dependant on insect pollination, such as the Ash Tree which had been in decline from invasive wood borers, made some comeback in population size. The production of most non insect pollinating crops were actually improved by the lack of insects. The self pollinating potato for example, was always at risk of being infested by the Colorado Potato Beetle which was resistant to over more than 50 types of pesticides (ted ed). Now potatoes and most root vegetables can be produced with little intervention from farmers. Without the fear of invasive insect species, the international market for agricultural goods grew. Soil quarantines like the one placed the southern region of the United States were lifted as there were no more fire ants to worry …show more content…
One of the most important of these being the lack of insect detritivores. The lack of flies resulted in built up of decaying matter from rotting flesh to decaying leaves. This build up of matter quickly overwhelmed both ecosystems and abiotic waste management systems. Bacterial illnesses became increasingly common in even some of the most affluent countries. Lack of insect detritivores has also reduced resource availability for plants and much more for vertebrates creating a loss of organically produced nutrient rich soil and an increase in vertebrate pest and scavengers such as rats and feral
From 1865 to 1900, production of crops increased, and prices dropped. Document A. These crops were shipped east, where they were eaten and exported to other countries. This was due to technology, but government policy caused economic conditions in the west to barely improve as a result. In fact, despite the success many farmers experienced, many in the West still struggled to put food on the table.
The changes in American agriculture was molded by three key factors, economic change, government policy and technology, in the period of 1865-1900.Technology helped facilitated production of good as well as their transportation. Farmers were able to produce more goods, yet they overproduced and it resulted in economic hardship for them. They could not afford to export goods through the rail roads high rates, and led to clashing with the government, for the lack of support. Such factors resulted in change of American agriculture.
The Roaring Twenties approached and the citizens in Colorado were facing rough times. In 1920, many people such as farm owners, manufacturers, and even miners were having a hard time making a living due to an economic downfall. The farmers especially, where facing the toughest of times. The price of various farm-grown goods like wheat, sugar beets, and even cattle was dropping because their goods were no longer needed by the public. Wheat had dropped in price from $2.02 in 1918 to $0.76 by the time 1921 came around. Sadly, the land that they were using to grow wheat became dry and many farmers had to learn to grow through “dryland farming” which became very popular in the eastern plains from 1910 to 1930 (Hard Times: 1920 - 1940). Apple trees began to die due to the lack of desire for apples, poor land, and decreased prices. Over the course of World War I, the prices of farm goods began to increase slowly. Farmers were not the only one facing this economic hardship while others in big cities were enjoying the Roaring Twenties.
Some of the insects, such as locusts, had intruded upon the once lush, and prosperous harvest spaces, and left only dried straw and grass behind. It was assumed that by the mid 1930’s, the Prairies’ agricultural practices would change drastically. Consequently, the poor harvesting conditions resulted in farmers moving their families and practices elsewhere. Many farmers moved to the northern regions of Canada, either picking up where they left off in the agricultural industry or shifting careers completely and moving into the bush clearing business. Those who were not able to obtain a job or adapt to the conditions were left unemployed.
As in any time period, significant technological advances were made from 1877 to 1933. Since the beginnings of the Industrial Revolution in America, new technologies and advancements are being made every day. This Revolution has transformed the economy and in turn transformed every aspect of American life. An important effect of the Industrial Revolution was the Agricultural Revolution, when new advances in farming were made. In the area of farming, the government passed laws and regulations that were significant in the ...
Crops today are thriving, and farmers can owe it all to the pesticides they use. If no pesticides were used, then insects would destroy crops, feeding off of their leaves and produce until hardly anything is left. According to corncommentary.com, Without the use of pesticides and fungicides, most fruit and vegetable crops would suffer a 50-90 percent loss due to uncontrolled insects and disease organisms. Despite what most people believe, even organic growers use pesticides on their crops that have been approved for such organic growers. Even they know that the wrath of insects and other disease organisms would destroy their plants and their profit they would have made from those plants. Also, without things such as weed killers, people would have to till the soil around their crops by hand. On large scale farms, this would take a huge amount of people to complete a task like this. The weeds would have to be pulled up, by their roots to ensure they wouldn’t grow back rapidly. On top of that, the crop would have to be routinely checked for weeds, as they grow fast and of many. The amount of money it would take to pay all the workers, and how often they would need to be paid for their work, is not owned by any farmer. Pesticides, herbicides and fungicides are what help keep our crops protected and healthy. Without them, we would be in deep
Between 1865 and 1900 technology, economic conditions, and government policy influenced American Agriculture greater than it ever had before. Technologically, Railroads, factories, and farm equipment changed American agriculture by allowing the production of farmed goods to be increased substantially, while economic conditions caused the prices of these goods to go down and then fluctuate. Farmers hurting from the economic disarray began influencing the laws being passed to help them in their economic troubles. Because of the influence of technology, government policy, and economic conditions between the 1865 and 1900 American agriculture was affected.
Crops such as cotton and wheat, once the sustenance of the agriculture industry, were selling at prices so low that it was nearly impossible for farmers to make a profit off them. Furthermore, improvements in transportation allowed foreign competition to materialize, making it harder for American farmers to dispose of surplus crops. Mother Nature was also showing no mercy with grasshoppers, floods, and major droughts that led to a downward spiral of business that devastated many of the nation’s farmers. As a result of the agricultural depression, numerous farms groups, most notably the Populist Party, arose to fight what the farmers saw as the reasons for the decline in agriculture. During the final twenty years of the nineteenth century, many farmers in the United States saw monopolies and trusts, railroads, and money shortages and the loss in value of silver as threats to their way of life, all of which could be recognized as valid complaints.
In the 1920s the American agricultural complex embraced the new technologies being developed. The internal combustion engine brought about new tractors and more sophisticated combines and harvesters. These new machines made it possible for
The 1920’s were the singularly most influential years of farming in our country. The loss of farms following the war, and new agricultural practices resulted in the dawn of modern agriculture in our country. The shift from small family to big corporation during this time is now the basis for how our society deals with food today. Traditional farming in the 1920’s underwent a series of massive transitions following WWI as the number of farms decreased and the size of farms increased.
Mosquitoes carried the diseases and when a person got bit he would give a disease to the mosquito and the mosquito would pass it on to the next victim ("Historical Overview").
The disorder is caused by a mutation in the ACADM gene. The ACADM gene codes for the primary enzyme that metabolizes medium chain fatty acids. The mutation causes a deficiency of the primary enzyme, Medium-chain acyl CoA dehydrogenase (MCAD), which is responsible for metabolizing fats into energy.
People today, and in history have not been able to cure all diseases that plague the world ,and harm people in different ways. In 2016, the Zika virus is what plagues different places in the world. While in 1346 The Black Death is what plagued most of the world and caused so much panic along with millions of deaths. The human race can’t get rid of every danger that threatens life but they can control it. The Black Death is a great example on how today people have the mental awareness on how to control a problem such as the Zika virus.
The use of pesticides such as DDT and PCBs that helped to reduce the population of harmful insects that plague fields before the 1970s. Nevertheless,
Agriculture has changed dramatically, especially since the end of World War II. Food and fibre productivity rose due to new technologies, mechanization, increased chemical use, specialization and government policies that favoured maximizing production. These changes allowed fewer farmers with reduced labour demands to produce the majority of the food and fibre.
