Farming experienced little change from the end of the medieval age until the middle of the twenty-first century. (Baker, 2014) When the tractor became the common farm tool and replaced the horse, crop yields remained much the same. (Baker, 2014) From 1866 until 1938, corn yields in the United States were reported at 30 bushels an acre. This, when compared to medieval yields, is not much higher than a good growing year in medieval times. (Baker, 2014) Innovation was drastically stalled by the Second World War and the Korean conflict. However, by 1951, crop yield began to steadily increase as new technologies like fertilizer and hybrid corn breeds became more readily available in the United States.(Baker, 2014) After the introduction of these innovations, corn yields in the United States, from 1952-present, showed an increased yield of 2 bushels an acre per year. (Baker, 2014) This simple increase, not only of corn, but other grain sources has led to a huge increase in the population of the world.
The population has increased more rapidly in the last 200 years than any other time in history. This may seem like a relatively short time, but when compared to the history of agriculture this is a very short time period. Consider that it took over 1000 years for the world to reach a population of 1 billion and only 207 years to reach 7 billion. This is an exponential explosion in the population. Throughout history, agriculture, through several revolutions, has made it possible to sustain the world population. Through innovations such as the plow, crop rotation, and fertilizer, yields have grown and supported the population. But how will modern agriculture support a population of 7 billion people? There is n...

- Genetically modified organisms or “GMO’s”, are organisms whose genetic characteristics have been altered using the techniques of genetic engineering. There has been much controversy surrounding the topic, and new scientific advancements will certainly continue to pose further disputes. The fundamental phases in genetic engineering include identifying a trait, isolating that trait, and the inserting that trait into the desired organism. In other words, it’s about the gene you want to transfer and put into the new organism.... [tags: Genetically modified organism]

- Prolific American journalist for The New Yorker Michael Specter, in his 2010 CNN article “Fear of Science Will Kill Us,” explains that “all the food we eat has been genetically modified. None of it was here before mankind learned to cultivate crops. The question isn’t whether our food has been modified, but how.” (Specter 2010). In recent years, propositions for labeling laws have risen in virtually every state. These labeling laws would require foods using GMOs to be easily identifiable by those perusing for foods....

- Much like land, the Ocean holds bounty for humans, the riches coming in the form of fish. With 90 million tons of seafood being fished from the ocean every year (Walsh, Ramzy and Horn). The Ocean, once looked at as an endless source of food, has continued to become more depleted over the last five decades. The Food and Agriculture Organization reports” that 32% of global fish stocks are overexploited, depleted or recovering and in need to be urgently rebuilt”. (“The State of World Fisheries and Aquaculture”) While larger species of fish such as marlin, swordfish and tuna have been fished out by as much as 90% (“The State of World Fisheries and Aquaculture”)....

- Genetically modified organisms Genetically modified foods are found in almost every store and are very common in America. Genetically modified organisms (GMOs) is a very controversial and heated topic in the agricultural industry. Humans first began to genetically alter organisms and crops in the 1990’s and began to be widely used in the early 2000’s. This new technology has scared many uninformed people who fear change and new agricultural techniques. GMO fearing individuals need to realize the benefits of GMO’s; genetically altered crops are the future of agriculture.... [tags: famine, agriculture, yield]

- Naively, we human beings believe we live in the dazzling golden age of technological advancements. Only, news flash: we’re not. Global food insecurity is at an all-time high. We’re struggling to feed a population that rises as quickly as the mercury in my thermometer. As demand soars and food dwindles, the men in power only seem to grow in size: from their wallets to their waistlines. So, you must ask yourself: what’s the easiest way to produce high quality crops to satisfy our hunger and their lust for money and power.... [tags: Genetically modified food]

- Food, an extremely important factor in the health of all living organisms. It gives our bodies nutrients and energy which allow us to continue on the journey of life. However, with the increase in population more and more food is needed to feed the human race, or is it. The weekday vegetarian diet is a relatively new idea that would help reduce land and resources needed for agriculture, reduce the amount of greenhouse gas emissions, as well as increasing the overall health of those participating....

- Protozoa - Protozoa are single celled organisms. They come in many different shapes and sizes ranging from an Amoeba which can change its shape to Paramecium with its fixed shape and complex structure. They live in a wide variety of moist habitats including fresh water, marine environments and the soil. Protozoan infections are parasitic diseases caused by organisms formerly classified in the Kingdom Protozoa. They include organisms classified in Amoebozoa, Excavata, and Chromalveolata. Examples include Entamoeba histolytica, Plasmodium (some of which cause malaria), and Giardia lamblia.... [tags: Bacteria, Microbiology, Infection]

- Genetically Modified Organisms Genetically Modified foods are tested over 120 times before they are passed by the Food and Drug Administration (FDA). Genetically modified organisms are inspected by the United States Department of Agriculture (USDA) to ensure the safety of the new varieties of plants that are produced. The Animal and Plant Inspection Service regulates the research development by requiring permits for testing of the new varieties. The population of the world is said to reach ten billion by 2050 and with genetically modified foods farmers and ranchers can withstand the growing population and feed the world....

- In the past 20 years, genetically modified foods have become more popular due to their health benefits and higher growing rates. Genetically modified organisms have many advantages but can sometimes have negative effects on the environment. Genetic engineering is used by scientists to enhance qualities in crops that are grown by farmers. Some of the qualities that scientists engineer these crops for are taste, nutrition level, and shelf-life. The technique that scientists use to increase nutrient levels is called nutritional enhancement.... [tags: nutrition, health, crops]

- ... If a product such as this was successful it could mean packing more nutrition in less food for countries where land and resources to grow food are scarce, coupled with lack of resources to import food. Aside from health benefits, there are also many health concerns. A health reporter for ABC News, Sydney Lupkin, refers to the fact, "... that people with food allergies may accidentally eat a "safe" food without realizing one of its ingredients has been spliced with genes of an allergen"(Lupkin)....
