The creation of genetically modified animals the altering of an animal?s genetic codes to make sure that it displays only the expected characteristics and do not possess any undesirable qualities. This is done by the addition of genes from other species, the deletion of undesirable genes or modifying the existing genes to bring certain traits forward. Though chimeras and cross breeds have been pretty much a staple in science fiction novels, nowadays, it is a wide known fact. The popular techniques to create genetically modified animals include pro-nuclear micro-injection, embryonic stem-cell manipulation and nuclear transfer. Genetically modified animals such as rabbits, cows, goats, pigs, rats, mice and cats are created with these techniques to arm them to serve their expected purposes.In the face of medical research however the increased benefits of organic food over conventional food stuff is yet to be proven, which has led the even the FDA and the USDA to claim that non organic food is just as nutritious as organic food stuff. However certain foods do carry some superior benefits of organic food, for example it has been revealed that organic milk and tomatoes are far superior to its non organic counterparts. For example organic milk is shown to contain more antioxidants and Omega 3 fatty acids and vitamins than non organic milk. These findings are according to the University of Aberdeen?s Danish Institute of Agricultural Research and the Institute of Grassland and Environmental Research, who claim that organic milk is of better nutritional quality due to the fact that the cows are pasture grazed and in addition .The major disadvantage is the speculation that these pesticides and resilient genes can pass on to consumers to create u desirable conditions for them such as allergies, diseases and cancer. Though any of these effects are yet to be proven or actually reported, genetically engineered food continues to stock up super market aisles a nd to be purchased over natural foods. Nowadays, over 65 percent of food items are genetically engineered food or made with popular genetically enhanced components such as corn, rapeseed (canola) or soy. Even though reports exist that laboratory animals that have been fed genetically engineered food have suffered considerable organ damage and illnesses, humans are apparently immune to these effects. But the speculation hasn?t died that it may affect the future generations and their genetic makeup.

It is estimated that over 70 of the processed foods in the United States contain some form of genetically modified ingredients , in light of these revelations it is about time we stop messing with mother nature and stick to the natures bounties with worms and weeds and all
