Genetic engineering refers to the direct manipulation of the genetic information of living beings. Genes, embedded in DNA, are the blueprints of life that determine the particular traits of an organism. Thanks to biotechnology, genetic engineers are able to replace these genes from one organism to another, resulting in completely new combinations of traits that do not exist in nature. These genetically modified organisms are artificially enhanced to express desired characteristics that are useful to us. Although genetically modified foods introduce many new beneficial possibilities, such as increased nutritional value and high agricultural yields, they also carry a wide range of risks to human health and the natural environment and can have serious unintended consequences in the long term. Human nutrition has been a topic of debate for decades. Despite all the controversies and protests, genetically modified crops and plants have been part of our diet for quite a long time. The first genetically modified food grown commercially was a tomato named “Flavr Savr”. Produced by the Californian company "Calgene", the tomato was able to resist the natural rotting process.() It was licensed for human consumption by the United States Food and Drug Administration (FDA) in 1994.() Since then, varieties of genetically modified foods have replaced our natural diet. As of 2013, approximately 85% of corn, 91% of soybeans, and 88% of cotton produced in the United States are genetically modified.() According to recent estimates, 75% of all processed foods contain genetically modified genes.() This Sudden rise of GMOs is the result of ever-increasing food demand on limited agricultural land. The current world population is around 7.1 billion and UN projections show that it is likely that genetically modified crops and plants will be restricted on farms and there will be no opportunities for them to breed with wild species, but even they believe the risk is certain. Genetic engineering is certainly a breakthrough in biotechnology with the potential to end the global food crisis and malnutrition. It has the potential to remove the immense pressure on agriculture with more yields and less land. With less land needed for agriculture, genetic engineering can restore lost ecosystems to the environment. But the potential harms of GE products are unpredictable and unpredictable. Rather than creating new ecosystems, its known and unknown effects can create large disruptions throughout the global environment. Thus, genetic engineering can create irreparable damage to our natural environment and threaten the existence of the living Earth..
