Nowadays, it is more convenient and easier for people to travel to other countries. Is this a positive or negative development?

In recent times, cross-border traveling for has become easier than ever before. Even though this is helping them acquire knowledge and discover new things and ideas, it does have some downsides.

Nowadays, as undertaking journeys has become cheaper and more comfortable, it is allowing people to see and experience disparate cultures more closely. Consequently, they are able to inform themselves about other cultures; expose them to heterogenous lifestyles, clothing, languages and food habits; and convince them that distinctiveness is perfectly normal, thereby making them more tolerant. Apart from that, now everyone can explore every corner of world, regardless of their economic backgrounds, and expand their list of destinations for leisure travel.  

On the flip side, this phenomenon also has some pitfalls. The main problem is that it is bad for environment since most of those going to other countries tend to fly, it is causing a rise in air pollution and also resulting in ecological destruction, by virtue of deforestation being accelerated due to the need for  bigger and more airports. 

Also, travellers may introduce new diseases to a place. For example, visitors to a new place often go to places where tribals live, making the latter vulnerable to viruses and bacteria, affecting their lives consequently. This can be corroborated by citing the  example of recent unrestricted proliferation of Corona Virus that citizens of one country  carried along with them and transmitted it to the hosts, causing pandemic as a result. 

In short, even though this evolution also has unfavorable consequences for the environment and host populace, the ease of traveling has certainly enabled more and more people to visit various places and learn about destination locations. Thus, this is a beneficial trend though precautions must resorted to in order to evade disastrous outcomes.
