Biotech innovations
The development of genetically modified organisms (GMOs) offer the probable for enlarged agricultural productivity or improved dietetic value that can provide directly to enhancing human fitness and development. From a health outlook, this innovation has some added advantages, such as minimal use of agricultural chemicals and improved farm earnings, and improved crop sustainability and food security, mainly in developing countries. The improved breeding of crops, livestock and fish, is aimed at increasing resistance to diseases and pests as well as overcoming the resistance that has been developed by diseases over time. The advancement of cellular genetics has improved the varieties of stable food that contained the traits for higher production (Hope, 2008).
The recombination of DNA in the last 20 years, a method to defeat the limitations of species inappropriateness was discovered by the scientists. The new technique of current trends in biotechnology makes use of molecular system to identify and alter DNA series for a particular trait from donor organism and transfer to the other organism so as to improve resistance.
This method of modification is quicker that the traditional breeding system since it requires only few generations to show the effect .Furthermore, it easily allows a specific change in an organism instead of what is seen in the traditional method as it only transfers specific genes required. However, it results in randomized insertion in the gnome found in the host, and this may lead to developmental process which was not intended or physical effects (Castle, 2009). It is trough this process that resistance to nematodes in a GM potato has been achieved and this is a clear indication that food security is improved throughout the world. This process has also altered the nutrition and composition of some food like rice to better positions by boosting vitamin A it contains. Vitamin A is very important to increasing resistance to diseases, protecting against visual impairment and blindness thus improving growth and development. The deficiency of vitamin A has been a treat to public health and has always contributed to childhood mortality. Rice has also been transformed trough this innovation to carry the required amounts of iron thus reducing iron deficiency which has been posing treat to human health.
The use of advanced technologies in biotechnology to decrease the levels of toxic chemicals in cassava would minimize the time required to prepare and save the lives of those people who use it as a stable food. The insertion of an invertase gene from yeast reduces the levels of glycoalkaloid toxin. Biotechnology has attempted to improve the photosynthetic system in plants trough genetic modification and this would lead to improved efficiency with enhancement in yield.
The fresh availability of GMOs could, on the other hand, carry possible dangers to human safety and living. Most of the features and traits that are found in modified agricultural products are new and have not been tested of their safety use before. Genetically modified organisms may also have effects on human health directly through unfavorable influence on the economy, and sociological factors. The introduction of transgenic into a recipient organism cannot easily be controlled and hence can result in a variety come which can be risk to the entire environment.
Ethical drugs are those that are exceptionally availed with the written instructions from a doctor. The instructions are usually directed to a pharmacist. The prescription gives authority for the particular drug to be sold.
