Genetic engineering just speeds up this process and can predict an outcome with greater regularity. It is not unlikely that children will sue their parents for wrongful genetic selection. In return, more food can be shipped to areas of the world where food insecurity is a major problem. Bioprospecting has gone on since very ancient times. Benefits and risks of genetic engineering Applications Genetic engineering has also been applied in medicine where it has been used to try and cure diseases like cancer. Pros of genetic engineering It has tried to cure certain diseases and has lead to the elimination of faulty genes and replacing them with better ones.
Once these sequences are known together with the mutations which cause or predispose to disease cures can be sought by designing appropriate molecules for use as pharmaceuticals. A larger yield means more profits for the agricultural worker, which means more innovation in this sector can be funded. The process of genetic engineering allows for the structure of genes to be altered. The pathogens can kill the target organism or could spread into the environment with unpredictable and dangerous consequences. There were only 29 early embryos created, and 13 surrogate mothers were used in the effort to create Dolly. Although genetic engineering seems like it would increase diversity, it actually decreases it. The Earth is already showing the strains of supporting too many people at once, and preventing natural death can have serious implications for employment, living space, food and energy sources and much more beyond.
There is no reason why an organism which just happens to be at a particular location of the globe should be in the sole ownership of the people living there. This gives farmers the ability to expand beyond the traditional locations and use the empty lands for other purpose. Of that, 71 survived and 54 were genetically tested. Crops are being created whereby they are resistant to diseases and pests and also need less water to grow. Is a sustainable agriculture, because it reduces chemical inputs as well as fuel inputs for farm machinery. List of the Advantages of Genetic Engineering 1.
Human discovery and invention can be thought of as resulting from the exercise of God-given powers of mind and reason. Decline in natural strength and resistance: Though these genetically modified varieties are said to be resistant to diseases, it seems they are still prone many other types of diseases for which they were not designed against. Human genomics is a continuation of mechanistic medicine to its logical conclusion. In fact, even their physical capabilities and mental faculties including memory and intelligence can be improved upon. May Hamper Nutritional Value Genetic engineering on food also includes the infectivity of genes in root crops.
The whole person includes their biography and the particular illness is part of that biography rather than just a property of the genes. In food, genetic engineering is able to produce completely new substances like proteins and other nutrients. While Dolly the Sheep did live to see more than five years, she also had a couple of health scares that shortened her life. The Top 4 Genetic Engineering Disadvantages 1. There are many advantages that genetic engineering can bring the world today. Bananas are constantly threatened by different types of disease. According to religious pundits, modifying the creations of God is akin to challenging His supreme authority and propagating the notion that His view of the human world is incorrect.
A good basis for considering how we should proceed with animals is given in the. For example, you can modify a plant to need less water, but that would make it intolerant to direct sunlight Pros and Cons of Genetic Engineering, 2014. Foetal stem cells created in this way are totipotent, i. This could lead to the affected wild plants becoming invasive weeds. Each experiment independently confirmed that there is no significant difference in the animals' ability to digest the genetically modified crops and no significant difference in the weight gain, milk production, milk composition, and overall health of the animals when compared to animals fed the traditional crops. So-called refuge systems do not work, partly because breeding cycles in the differing pest populations are not synchronised. Non-Predictable result Another disadvantage of genetic engineering are that we do not know what would be the possible side effect there could bring.
People would identify specific traits, seek out other plants or animals that had similar traits, and then breed them together to create a specific result. This knowledge and technology can be easily abused. Experiments in animals show that future therapeutic cloning of human tissues for implantation could take place without involving an embryo stage. This can alter plant diversity. Genetic engineering deals with these factors of genes and modification of genes are being done in this form of science.
Some groups have recommended changes to the law to allow people access to genetic information from people to whom they are closely genetically related. Less insect damage means less opportunity for fungi to infect the plant and bring toxic substances. But yet there are many problems associated with this technique. While there are many genetic scientists who have pure intentions to make the worst diseases today a thing of the past, it is also believed that there are others who would take the research too far. In fact, they can even end up in unexpected places. Gene therapy can then be used to correct the defects in the infant. In the field of biotechnology, genetic engineering paved the way for xenotransplantation or the process of transplanting living tissues or organs from animals to humans or vice versa.
