Genetic engineering also known as genetic modification is the direct manipulation of DNA to modify an organism’s traits mainly observable physical properties in a specific way. Scientists utilize it to improve or change the features of an individual organism. It may be used to treat anything from a virus to a sheep. For example, genetic engineering can be utilized to create plants with better nutritional value or that can withstand pesticide treatment. It has also been used in animals to create sheep which would generate a therapeutic protein in their milk that can be used to cure cystic fibrosis, as well as worms that glow in the dark to help scientists understand more about illnesses like Alzheimer’s.

Firstly, if we look at the history, it was created to aid in the prevention of disease transmission. With the advent of genetic engineering, scientists may now alter the way genomes are built to eliminate illnesses caused by genetic mutation. today, genetic engineering is utilized to treat diseases including cystic fibrosis, diabetes, and a variety of others.

 Genetic engineering also helps in detecting the problems even before the child is born which in turns help in curing the illness and diseases in unborn children. Humans aren’t the only ones that benefit from genetic modification. We can use genetic engineering to create foods that can endure extreme temperatures such as very hot or very cold while also providing all of the nutrients that people and animals require to thrive. Animals and plants can have their development rates genetically altered to mature more quickly. In order to improve productivity od diary or meat or even wool, animals can potentially be genetically changed. 

However, with advantages comes disadvantages as well. Thus, Allowing scientists to tear down boundaries that should maybe be left alone has a lot of drawbacks.

Many religions, after all, think that genetic engineering is equivalent to playing God, and ban it from being used on their children, for example. Aside from religious issues, there are a variety of ethical concerns such as longer life expectancy is already generating societal difficulties throughout the world, so intentionally extending everyone’s life on Earth might lead to much more problems into the future, ones that we can’t possibly anticipate. Genetic engineering can also lead to genetic defects which scientists really can’t foresee because human body is a complex structure.

Furthermore, Genetic engineering aids in the resolution of a problem by introducing genes to the organism that will assist it in combating the issue. This can have unfavourable consequences. A plant, for example, may be engineered to require less water, but this would make it intolerant of direct sunshine. Also, nature being a complicated web of interconnections, many side effects can be caused as a consequence of using genetically modified genes. 

Therefore, In a world where genetic engineering is advancing at a breakneck pace, the dangers of going too far with it are a constant source of concern because no one can’t really anticipate what consequence will it create  and where it will lead us. Changing creatures’ DNA has definitely raised a few heads. It could work wonderfully, but who knows whether interacting with nature is truly safe. As a result, it appears that genetic engineering is both a mixed blessing, as we stand to gain as well as lose by furthering this field of study.
