The importance of LMO

Since human population has increased dramatically, the demand for food is increasing also to fulfil the myriad population. Moreover, climate changes caused the natural disasters like flood and drought to happen more often, resulting in uncontrollable disruption to crops and livestocks. Hence, to overcome these problems, scientists come out with a solution, Living Modified Organisms (LMOs) which is also known as Genetically Modified Organisms (GMOs). One of the intentions of LMOs is to overcome food crisis. Genetically modified (GM) crops are designed to enhance their qualities such as longer storage, higher crops yield, ability to grow larger, and reduced cost in aspect of food production, need for herbicides and insecticides as well as higher nutritional value. Another concern is that LMOs nowadays are associated with pharmaceutical value, for example, vaccination does not need to be done via injection but we can have vaccines get into our bodies by the practice of LMOs consumption in the near future.
The statement of Lusk and Miller (2014) clearly pointed out the importance of LMOs nowadays especially in the aspect of economy, as the land for farming getting less. Consequently, food production will be lesser whereas costs of production will increase significantly. Nowadays in US, 90% of the farm land is used to plant genetic modified wheat and soybean. Indeed, economic gains in US from 1996 to 2008 were more than $50 billion (as shown in Figure 1). With the molecular engineering technology, the prices of food will be more affordable for the poverty. As stated by Chen and Tseng (2011), agricultural food prices had decreased about 2% per year from year 1961 till 1999.

Production through 1996-2008 (Peterson, 2009)

Since we know the benefit of bioengineered crops, but how exactly the bioengineered crops work to enhance yield? Take the glyphosate herbicide tolerance soybean as an example, the herbicide resistance gene is isolated from Agrobacterium tumefaciens, strain CP4, which allows the soybean to produce an enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) that makes the bioengineered soybean become resistant to herbicide. Another example, insect resistance corn, had been genetically modified by insertion of a gene from bacterium Bacillus thuringiensis. The expression of this gene will produce insecticidal protein Cry1Ab, which is a toxin (Phillips, 2008). When corn borer ate the corn, Cry1Ab protein binds to specific receptor protein in the wall of the larva intestine, causes damage and eventually the larva get kill (Bessin, 2003).
LMO not only helps to solve food crisis, it also enhances the nutritional value of crop, such as the case of golden rice that rich in Vitamin A. In Asia and Africa, there are millions of children especially in the third worlds, having eye diseases like night blindness due to the lack of Vitamins A intake (Charles, 2013). Golden rice is a solution to supply vitamin A to the...

The Danger of Genetically Modified Organisms

1370 words - 5 pages How well do we know the food we are eating? Ever wondered whether these foods are safe? In the recent years, people have become more aware of how genetically modified foods have substituted our diets with altered foods -- to which little we know about the long term effects on humans. These food being fed to us is called Genetic Modified Organism or GMOs. Just in 2012, prop 37 was proposed in California, which would have required labeling of

The Role of Water in Living Organisms

987 words - 4 pages The Role of Water in Living Organisms Water is one of the most abundant molecules on planet earth; it is found in vast amounts not only in earthly enviroments (oceans, lakes and rivers), but is also present in the atmosphere, and as solid ice in the two poles. Consequently it is rather logical that water plays an important role in biological life: the origins of life occurred in water and life itself wouldn't be able to

Description of Genetically Modified Organisms

2169 words - 9 pages What are GMO’s? They are genetically modified organisms. They were created in a laboratory back in 1972, when scientist spliced a strand of virus DNA and a strand of bacterium DNA, recombining them together creating what was termed a “recombinant” molecule. This process was then used to produce genetically modified foods also known as genetically engineered foods or GMO’s. These foods began to be distributed for consumption by the general public

Genetically Modified Organisms: The Facts

1607 words - 6 pages Introduction Any organism which has its genetic sequence altered by insertion of a piece of foreign genetic material is considered to be a genetically modified organism, or simply, GMO. The recombinant DNA technology (or gene cloning) allows such modification by using enzymes that are naturally found in almost all organisms. A restriction enzyme is used to cut a specific DNA segment of a ‘donor’ genome and to generate sticky ends in the ‘host

The properties and biological importance's of water to living organisms

1489 words - 6 pages Water is a simple molecule, yet it is fundamental to life. In active living cells, two-thirds, or often more, of the area is occupied by water, and two-thirds of the globe is covered in water. Water is therefore extremely abundant, and in biological terms it has great importance both inside cells, and externally, for example as a habitat The simple molecule of H2O has many interesting physical and chemical properties which contribute to its

Fish for example are able to live in water and are adapted for this purpose; they respire using the oxygen that is dissolved into the water as the result of it being a good solvent.Conclusively water is vital to many aspects of both human and plant life. Its excellent range of chemical and physical properties allows it to be used in a wide variety of

In "Human Biology" by J.M Orten and O.W. Nevhans, it is suggested that 70% of all body weight is water, most of which is found in three major compartments: 70% intracellular fluid, 20% interstitial fluid (lymph) and 7% blood plasma

Genetically Modified Organisms: Modifying the World’s Industries

1273 words - 5 pages The founding of genetically modified organisms was extended through the course of many years. It began in 1865 when Gregor Mendel observed hereditary characteristics in pea plants. Nearly forty years later, Andrei Nikolaevitch Belozersky was the first person to isolate DNA, or “factors”, as Mendel defined it, in its pure state (Life Sciences Foundation, Purification of DNA). This revelation sparked the start to DNA innovations. After the
