Each other - Tradução em português

Olá, gostaria que me ajudassem com a tradução de each other.

Why do we need to learn English?
Of course one of the reasons why we need to be able to speak English nowadays
is because the world is becoming smaller
thanks to the Internet
and our developing global economy.
more and more people are using English
as a common way to communicate with each other.
