There is controversy surrounding genetically modified crops. to make informed decisions, scientists must weigh the pros and cons of using this type of biotechnology. explain why genetically modifying the foods we eat can be both useful and potentially harmful.

The pros of using GMO are that they result in higher yields than natural food crops hence able to feed a growing human population on earth. They are also able to withstand crop diseases and pests hence improved yields.

The cons of transgenic plants contribute to antibiotic resistance especially due to the use of antibiotic resistance genes in recombination genes. Another is the environmental impact. GMO may result in uncontrolled gene transfer to natural crops in the environment hence created challenges such as super-weeds.
