Nowadays, people all over the world are becoming more and more connected, as if the world were getting smaller — as if we were living in a “global village”.
Technology is largely responsible for bringing people together. Channels of communication, such as the mobile phone and the Internet, have made it possible to speak instantly with someone on the other side of the planet, enabling us to form close connections with people of completely different cultures. The television, meanwhile, is a window on the world, giving us quick and easy access to other cultures and lifestyles.
Cultural exchange helps us to be more inclusive and to overcome culture shock. But inclusiveness doesn’t mean that our cultures will merge into one another. Rather, it’s about countries and people making a joint effort to come together to create a more harmonious and understanding world, so that we can all enjoy the mutual benefits.
