Genetic Engineering: The Solution to Hunger and Disease

         In case you were not sure, we don’t live in a perfect world. Millions of people die every year. Two significant causes of death are hunger and disease (I am aware that there are more causes such as war and crime, but they are irrelevant to this essay). There are about 5.6 billion people on earth; all of whom need to eat. However, only a certain amount of food (less that what everyone needs) can be produced. With the use of pesticides, much of the food that is produced is not as nutritional as it could be. Food production costs are also inordinately high due to the crop’s weaknesses to pests, pesticides, and weather fluctuations. On an ascetic level, tomatoes are tasteless. They have little nutritional value because farmers must pick them when they are still green so they won’t be too soft by the time they get to the consumers. On a global scale, millions of people die of starvation every year in third world countries. The worst famine in India killed 3 million people in 1770. Over 100,000 people have perished so far in the current famine going on in Ethiopia and Somalia (Wallace 1065). Disease is the other killer. I need not waste time talking about how many people die of disease because it is extremely common knowledge.

         There is hope. Every living organism has deoxyribonucleic acid (DNA). It is the genetic code which determines what the organism will be. Recently, scientists have been able to alter an organism’s genome to come up with desired characteristics. This is known as Genetic Engineering (GE). GE is the process of altering biological systems by the purposeful manipulation of DNA. For example, removing the gene which causes rotting in tomatoes will make the tomato stay firm for ten days longer that usual. Simply put, GE is the solution to hunger and disease.

         GE can come pretty close to ending hunger. The goal here is to improve the quantity of food from plants and improve the amount of milk and meat that cattle produce. There are three ways in which ‘agricultural engineering’ can be done. Scientists can mass produce the bacteria that plants need for nitrogen fixation. Another method of agricultural engineering entails the growing of individual plant cells in cultures in order to screen for genetically superior traits. A third method, and perhaps the most efficient, pertains to splicing new genes into plants and animals themselves (Weintraub 156). With respect to the third approach of plant engineering, scientists are working on splicing the genes needed for the production of 1- lysine, an amino acid which has nutritional value for humans. By enhancing the nutritional value of corn in some Third World countries, an expansion of food supplies would be unnecessary (Ellis 153). Other possibilities of gene engineering that evolve from gene splicing is the manipulation of a plantÕs genes that regulates photosynthesis, which increase plant...

962 words - 4 pages some seem unsupported. Jews are divided on the topic as they prone to Tay Sachs disease. “ The disease is controlled by a pair of genes on chromosome 15. If both genes are inactive the person has the disease and dies very young”. (Genetic Engeering Page 1) Genetic engineering is the only way to cure the disease by “artificial conception”. (Genetic Engineering Page 2) I believe that genetic engineering should be used to cure this disease and that it should be left up to the individual to decided to use genetically modified genes to replaced pathogenic ones.

However there can be great advantages to genetic engineering.      Biotech industries argue that by using genetic engineering they can produce crops which grow faster, produce better crops and can reproduce more easily, they argue that this has the potential to solve world hunger. However there is little

The Pros and Cons of Genetic Engineering

820 words - 3 pages Genetic engineering is the growing science of the world and is increasingly under the spotlight over ethical issues. Is biotechnology going to save lives, rather than destroy them? and will the benefits outweigh the risks? The main problem with such questions is that we don't know the answer until we try them out. Like all sciences it is hard to predict outcomes, so far there have been more failures being told than success stories. Genetic

Humans and animals are not the only thing that can be cloned or have their DNA tampered with. For many years, plants have been genetically engineered. These plants have been engineered to withstand drought and disease and are provided at a smaller cost. This is not only helpful to farmers but provides cheaper food for those in poverty to help with hunger

Despite other organisms in which this process can be carried out, biologists tend to perform the process on plants, for the process can be contained and is, for the most part, ethical. In terms of plants, the biologist must first sequester the genes to be used from one subject. Modern

If they do this, the economy would get hurt becomes small farmers would not be able to afford these new creations and keep up
