Views on Genetically Modified Plants


Genetically Modified Plants                                                        
            The genetically modified plants are those whose DNA is changed using some techniques from genetic engineering. By using such techniques a new quality is introduced into those plants which enable them to be sturdier and withstand diseases and pests, which normal plants cannot withstand (Bock, 2010).
            Even though there is a stubborn resistance to the introduction of genetically modified plants in a number of countries, their utility cannot be totally written off. Due to acute pollution and global warming, there are many unpredictable changes in climate, which normal and natural plants are not able to withstand. Because of such climatic changes new types of pests are targeting plant life, causing huge destruction. Genetic changes in plants enable them to be resistant to diseases and pests and also ensure longer shelf life(Bock,2010).
            Human needs are increasing day by day particularly on the food front. It is becoming more and more difficult to get the necessary crop yields from natural plants. Genetically modified plants can offer solution to this problem. However care should be taken that these genetically modified plants do not give rise to new environmental problems(Bock,2010).
