English is incredibly important because as young adults living in America, you need to be conscious of how you express yourselves. English provides the groundwork on which you will build all of your learning. Without a solid background in the English language, you will not be able to read, write, or speak well. This will adversely affect all of your other subjects in school and, ultimately, your success in life. Knowing how to present yourself to others and how to think critically about matters will help you now (as a student) and down the road in college or in the workplace.
