What would happen if everyone on Earth communicated in the same language?

Long ago, it is said that everyone on Earth spoke a single language, according to Judeo-Christian teachings. In an attempt to make a name for themselves, people decided to construct a giant tower reaching toward the heavens. Known as the Tower of Babel, their ambition did not sit well with God:

Then the Lord said, "If, as one people sharing a common language, they have begun this task, nothing they plan will be impossible for them. Let us go down and confuse their language, so they won't understand one another" [source: Net Bible].

It’s clear that God wasn’t in the best of moods that day.

The question of whether the Tower of Babel's story is meant as religious symbolism or an account of actual human history is still up for debate among scholars. Although there’s no definitive proof that ancient humans all spoke a single language, many experts argue that similarities among the oldest known languages, such as Greek, Latin, and Sanskrit, suggest that modern languages may share a common origin [source: PBS]. Dr. Noam Chomsky, a linguistics professor at MIT, states that "Every language that has ever existed is just a modification of something before it."

While the precise origins of each language remain unclear, it's certain that humans have never spoken a single universal language in recent history.

Linguists face a challenge in determining the exact number of languages in the world at any given time, mainly due to the ambiguity in distinguishing when a dialect becomes an independent language [source: Palomar]. Current estimates suggest there are 6,909 distinct languages worldwide [source: Ethnologue].

Despite the challenges in counting languages, experts generally agree on one fact: languages are rapidly disappearing. Some predict that by the year 2100, half of today’s languages will no longer exist [source: Pearson and National Geographic]. Historically, there may have been as many as 12,000 different languages around 10,000 years ago, when the global population was between 5 and 10 million [source: CLTA-GNY]. What does the future hold for language?

The Future of Language

Many specialists predict that we are moving towards a future where a single language will be spoken by everyone, particularly due to the influence of globalization which has made it easier to communicate across even the most remote areas. This could mean that people learn this universal language in addition to their own native ones. But this raises an important question: would the adoption of a common global language contribute to the erosion of linguistic diversity?

When we asked linguistic experts about this possibility, opinions were split, ranging from "highly unlikely" to "not in a million years." This is because language is so intrinsically connected to culture, family, and personal identity. The dominance of one language over another often correlates with political changes and shifts in power. If one country or region becomes more influential in global affairs, there would likely be strong motivation to communicate with the people there. However, there is a significant difference between speaking a dominant language for business purposes and speaking your native tongue, which for many, represents a link to their history and heritage.

Some might question whether a universal language could help reduce the animosity and conflict between nations. While it’s an interesting thought, it's debatable—after all, many violent conflicts have taken place between groups who share the same language, such as the North and South of Vietnam, the Protestants and Catholics of Northern Ireland, and different factions in Somalia [source: CLTA-GNY].

Nonetheless, there are considerable advantages for both individuals and societies when mutual understanding is possible. We'll explore some of these on the next page.

Can a Planetary Parlance Co-exist With Mother Tongues?

Language is only one part of the intricate and fascinating mosaic that defines humanity. This is why language lessons often come alongside an exploration of the music, cuisine, and customs of a given place. These cultural elements offer a deeper understanding of the values, beliefs, and shared history of a community. Ultimately, this leads to a more profound connection with the speakers of the language being studied.

Consider the possibility of losing the diverse languages of the world in favor of a single dominant global language. Dan Fitzgerald, a French teacher from Washington, D.C., warns that the impact on humanity would be immense. As he puts it, "Much of the culture that goes along with each of those languages would also disappear."

Now, picture a world where most people can speak a global language, yet retain their native tongues as their primary means of communication. The ability to communicate across linguistic borders would unlock incredible opportunities for work, education, and relationships that would otherwise be exceedingly difficult to form.

The idea of a universal global language inevitably brings up the question of which language would be chosen. Most experts agree that the answer would depend heavily on practical considerations that could change as political and economic power shifts over time. This is because language acquisition is primarily driven by necessity – there must be a compelling reason for people to take the effort to learn a new one.

Esperanto is a language that was created in 1887 with the intention of being a universal second language [source: Esperanto USA]. However, despite having only 2 million speakers globally, it seems unlikely to become a practical tool for worldwide communication. Dr. Matt Pearson, an associate professor of linguistics at Reed College in Portland, Oregon, believes this is likely because Esperanto never gained the status of the official language of a politically or economically influential nation or group.

Some may argue that English already serves as the global language. Spoken in over 100 countries, English is undoubtedly the most widespread language in the world. There are, however, other languages spoken by larger populations, such as Mandarin Chinese and Hindi, which are only spoken in 16 and 17 countries respectively [source: Palomar College].

While English may currently be the language of global communication, it could easily be replaced as global demographics and priorities shift. One thing, however, is certain: People will continue to hold onto their native language, regardless of its competitive advantages. Language is much more than just a means of communication; it is deeply connected to our personal identity, something too valuable to lose.
