Nowadays, engineers are very important in our society. They are highly successful in various fields such as medicine, robotics, genetic engineering and many more. From a scientific point of view, engineers are looking for the best tools and equipment to create the perfect product. Engineers focus on improving productivity and reducing costs associated with various aspects of production. Engineering is the way out of problems, usually related to the environment. Genetic engineering makes a disease-free future possible. Today, genetic engineering allows you to change anything for the better by influencing the genetic level. Most people think that using genetic engineering is a great idea to improve the world, because we can make better products. However, people do not think about the possible problems that may arise in the future using genetic engineering. Today genetic engineering is a powerful and potentially very dangerous tool if in the wrong hands. It can completely change a product that can be very useful or, conversely, extremely harmful to humans. Today's advances in genetic engineering allow therapy to replace the defective gene in a cell with a more refined gene that does not have this defect. Although these methods are available, they are still in the experimental phase. It allows anyone to change reality. Methods for creating an ideal society without defects and with a high level of intelligence are possible. Of course, if the gene develops without further negative consequences, this is ideal. However, if there is a defect associated with gene replacement, it represents a great threat to the future of our planet. However, one of the main problems...... middle of the paper ......ed . Therefore, the problem of food scarcity in third world countries can be solved by modifying plant genes that positively affect the quality of life of many people. In many countries, manufacturers do not mention on the label that the product is genetically modified, because they think this will result in forcing them to change their product. Many religious and cultural communities are against these products because they see them as an unnatural way of obtaining food. Many people also disagree with the idea of ​​transferring animal genes into plants. Additionally, this method can cause harm to other organisms that thrive in the environment. Experts believe that with the increase of such products, developing countries will begin to depend more on industrialized countries, because they are likely to control food production in the future.
