On the one hand, genetic engeneering has made global problems' solutioning much easier. For example, many people lшving in poor regions are suffering from hunger. Genetically modified crops, which are faster and cheaper to grow, may help to increase the number of production and reduce its cost. Moreover, medicines and vaccines often too costly to produce, so the third world countries can not afford it. Genetic engeneering helps not only to make producing medicines cheaper, but also to create new types of drugs.

On the other hand, introducing a gene into a plant may have an unpredictable impact on people's health. for instance, it may cause new deseases or allergic reaction. futhermore, many people nowadays are concerned that insects may become resistant to the crops that have been genetically modified, so scientists will have to search for another way of protectimg yield from plant pests.

To sum up, I would like to say that genetic engineering has both advantages and disadvantages. It goes without saying that since the invention of genetically modified crops people's life has become much easier. But we should take into account the possible impact of such products and be very attentive and careful
