Plz could anyone correct my essay

Everybody around the world should learn important skills that it's English language. Lean this skill has several advantage. If any on don't learn this skill, they will faced a lot of problem such as when they travel or a good job. In my essay I'll discuss both sides.

Nowadays, all jobs require English skills to employment any person. All people believe if they have this skills, they will be able to get a great job and a good income. Furthermore, because all the people around the world learn English, this skill important when you want to travel in other countries. That’s helpful to communicate with resident's their countries.

On the other hand, In contrast, if they don't know or have this skill, they don't have opportunities to get jobs like they want when they competing with other people have this skill. Moreover, when they travel in vacation without have this skill, they will faced a lot of problem. For instance, my uncle ,when he went to at the airport in the USA, he didn't spook English. He missed his next airplane to Los Angeles. He still waited in airport until he found someone who spook his language and help him.

In my opinion, if somebody learn English skill, they will be able have opportunities to get a good job and have a good communication with anybody around the world. However, people who don't have this skill will get a lot of problem when they travel on abroad.
