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.Farmers who grow genetically engineered food are greatly benefitted by their added qualities. Some genetically engineered food crops are modified to be able to withstand certain herbicides so that the farmers are able to use them liberally to get rid of weeds while others are created with built in pesticides that repel bugs and other pests. Other genetically engineered food is created with long life and resilience to adverse weather conditions in mind. For instance, some species of corns are created to withstand the harsh chill of winter and to keep them from rotting in heavy rains. Other species such as tomatoes which are one of the first vegetables to be engineered are modified to have a more vibrant colour, better taste and much longer shelf life and in many cases .Further research conducted by the Committee for Independent Research and Information on Genetic Engineering, which is a non for profit independent organization committed to study the impact of genetically modified corn as well as food in general recently corroborated the evidence of the earlier researchers that certain organs have been negatively impacted by genetically modified food, namely the kid neys, the liver, the heart, the adrenal glands and the spleen.

Due to the changes in climate, such as coldness, farmers are not able to do farming during certain periods of the year. Most of the foods do not tolerate extreme weather or climate changes, so as a result, crops may produce low volumes. In order to address this, genes of the plants that can withstand coldness have been added to the food producing plants, making the latter category more cold resistant. This is one of key benefits of genetically modified foods. As another benefits of genetically modified foods, in some other countries, paddy has been developed genetically where they can withstand low water supply. Water is one of the burning issues in some of the developing countries.
