1. With genetic engineering, most of the diseases and illnesses can easily be prevented through detecting the animals, plants and people who are genetically prone in a certain hereditary diseases.
2. There are also infectious diseases that can also be treated with the use of genetic engineering through implanting the genes that are associated with antigen and antiviral proteins.
3. With genetic engineering, plants and animals can easily determine their desirable characteristics. The genes can be manipulated especially in trees since when the carbon dioxide is being absorbed and this is one of the reasons why the threat for global warming is highly reduced.
4. Genetic engineering has the ability to increase the genetic diversity as well as produce variant alleles that can be implanted to other species. It is also possible to change the heredity of the wheat plants and grow insulin.
