Prompt 7 : Contemplating Controversy

Written by : Seungyeon Lee

Common pros about chemical engineering

1. Sources made of chemically are essential in human life.
Sources such as, oil, chemical materials, are essential in human life that it is impossible for us to live without them. People these days are very dependent on those chemical materials or energy sources like crude oil and coal. 
2. Chemical energy sources are easy to deal with and efficient. 
While other energy sources are hard to combust itself, chemical energy can combust itself easily. Combustion depends on the oxygen. Especially chemical energy sources has the highest efficiency of combustion which can allow to combust efficiently while other resources would not. Therefore, chemical energy can also be used for vehicle engine since it holds great amount of efficiency when used, which can save the energy than other sources.
3. It helps society and environment. 
Chemical energy is not only making products that are useful to people, they nowadays consider the environment so that when producing several products those won't harm environment too much.
Common cons about chemical engineering

1. It affects the environment. 
When producing materials, it pollutes the air and affects the environment. According to GreenGarbage blog, chemical energy is derived from organic materials. Therefore,  it is more likely that the organic materials contributes to environment pollution.
2. It comes with a high cost. 
Another disadvantage about chemical engineering is that most of the product they produce cost a lot of money. For example, nuclear power plants needs five to ten years to be produced. Therefore, it needs a lot of time and money to be proceeded and to be made.

3. They are non-replaceable.
Most sources made with chemical energy cannot be reused. Not only it is hard to dispose of properly, but also since it cannot be reused, it will be just remained as a waste. Therefore, even though things produced are essential for human's daily life, it is same as producing the waste that is hard to be replaced with any other thing than remaining itself as a trash.
