English is the most widely spoken language globally and is important to learn for three main reasons:
1) It allows people to communicate internationally and access global opportunities in business, education, and employment.
2) Technical and scientific knowledge is often documented and shared in English, so it is important to understand manuals and instructions.
3) Having English skills significantly increases one's chances of getting a job, as the ability to use English, either actively or passively, is a top requirement for many positions.
