In the 20th century, contact between different parts of the world has developed rapidly thanks to air travel and telecommunication. Do the advantages outweigh the disadvantages?

The acceleration of globalisation processes in the 20th century led to the blurring of borders between countries, as new modes of transport,

such

as aeroplanes, emerged and telecommunication infrastructure was created to keep countries in contact. Despite the seemingly positive factors of

this

trend, there are

also

negative aspects, both of which will be discussed in the following paragraphs. On the one hand, the creation of telecommunications

technology

has enabled

people

to communicate at a distance.

For example

, the

first

mobile phone was invented, which helped to transmit information over long distances. As far as

air

links are concerned,

this

has contributed to the

development

of tourism and the rapid movement of

people

between countries for work purposes and beyond.

Moreover

, the advent of telecommunications and

air

travel played an essential role in the exchange of information during the

Second

World War, as national leaders were able to report messages over special telephone lines rather than waiting for letters.

On the other hand

, with the

development

of

technology

and aviation came negative trends.

Firstly

, the process of environmental pollution has begun.

In other words

, due to the increasing frequency of planes that fly on fuel oil, the

air

has become polluted with various exhausts and harmful gases.

Secondly

, advancement in the telecommunication sphere spurred the

development

of spying methods and information theft, which are widely spread throughout the world.

As a result

, with the evolution of

technology

,

people

are threatened by cyber criminals who can steal personal data for selfish purposes. In conclusion,

although

the 20th century introduced

technology

and closer

air

travel that set the stage for future

development

, it has a number of drawbacks that affect

people

in the 21st century.

However

, the benefits of these trends still outweigh the negatives because they have triggered universal progress.
