Chemistry can be applied in many different fields such as water treatment, energy efficiency, renewable resources, preventing contamination and many others.
Don't make obvious statements. Give a unique insight into the applications of the subject.
The truth is I am extremely interested in all these fields.
Really?...that's fine, but to an AO that may seem like you don't have a lot of knowledge about your chosen field. A lack of knowledge is often one of the reasons for the generic choices. I don't mean to offend you, and I'm not implying that you have any lack of knowledge in chemical engineering. I just want to point out the different impressions your statement can make.
Moreover, you have not included even a single sentence which is specific to the field of chemical engineering.
Use your research, and say some unique and specific things about chemical engineering. What is it that really attracted you towards this branch? What do you want to become after you graduate?
