Explanation:
Language degradation is occurring because of the adoption of foreign languages.
<h3>How does this adoption take place?</h3>
The constant presence of foreign media and the adoption of foreign language terms is the main way to adopt a new language.
This adoption allows the local population to start mixing the two languages.
Over time this process becomes more intense, causing the local language to be replaced by a foreign language over time.
Language degradation is a process that occurs in many regions, but maintaining these languages is very important.
