Plant breeders try to create a specific oute of plants and potentially new plant varieties by changing the genes of the plants through breeding, which is making new plants from parents of different varieties or species. Crossbreeding can take such a long time, however, and it is inaccurate. Now, we can change exact sections of Deoxyribonucleic acid (DNA), so the process is more accurate and faster. But people all over the world are arguing about its benefits and disadvantages. Some people use the technology to produce desired characteristics of plants and animals. Other people are concerned that the genetically engineered plants may harm the environment and worried that they may be dangerous for people to eat. Some genetically engineered plants are more nutritious. They have less fat, taste better or stay fresher than nongenetically engineered plants. This will allow people to buy betterquality fruit and vegetables. However, genetically engineered plants can cause unexpected problems. Genetically engineered plants that resist pests may
