Manipulation of genes in natural organisms, such as plants, animals, and even humans, is considered genetic engineering. This is done using a variety of different techniques like molecular cloning. These processes can cause dramatic changes in the natural makeup and characteristic of the organism. There are benefits and risks associated with genetic engineering, just like most other scientific practices.

Genetic engineering offers benefits such as:

1. Better Flavor, Growth Rate and NutritionCrops like potatoes, soybeans and tomatoes are now sometimes genetically engineered in order to improve size, crop yield, and nutritional values of the plants. These genetically engineered crops also possess the ability to grow in lands that would normally not be suitable for cultivation.

2. Pest-resistant Crops and Extended Shelf LifeEngineered seeds can resist pests and having a better chance at survival in harsh weather. Biotechnology could be in increasing the shelf life of many foods.

3. Genetic Alteration to Supply New FoodsGenetic engineering can also be used in producing completely new substances like proteins or other nutrients in food. This may up the benefits they have for medical uses.

4. Modification of the Human DNAGenes that are responsible for unique and desirable qualities in the human DNA can be exposed and introduced into the genes of another person. This changes the structural elements of a persons DNA. The effects of this are not know.

The following are the issues that genetic engineering can trigger:

1. May Hamper Nutritional ValueGenetic engineering on food also includes the infectivity of genes in root crops. These crops might supersede the natural weeds. These can be dangerous for the natural plants. Unpleasant genetic mutations could result to an increased allergy occurrence of the crop. Some people believe that this science on foods can hamper the nutrients contained by the crops although their appearance and taste were enhanced.

2. May Introduce Risky PathogensHorizontal gene shift could give increase to other pathogens. While it increases the immunity against diseases among the plants, the resistant genes can be transmitted to harmful pathogens.

3. May Result to Genetic ProblemsGene therapy on humans can end to some side effects. While relieving one problem, the treatment may cause the onset of another issue. As a single cell is liable for various characteristics, the cell isolation process will be responsible for one trait will be complicated.

4. Unfavorable to Genetic DiversityGenetic engineering can affect the diversity among the individuals. Cloning might be unfavorable to individualism. Furthermore, such process might not be affordable for poor. Hence, it makes the gene therapy impossible for an average person.

Genetic engineering might work excellently but after all, it is a kind of process that manipulates the natural. This is altering something which has not been created originally by humans. What can you say about this?
