English is an international language and it is very vital tob e learned by anyone, but this does not mean we should forget about our local languages. In fact we have to try to make sure that our native and local languages are going to survive. Though there are several ways to let them servive, but I will mention two of them here.
The first way is through speaking our local languages among our friends and family, as matther of fact ,This will help us with our communication skills furtheremore, this way the local languages are also going not to be didicated to olders. My cousins, For example, always tend to speak english with each other ratheer then Farsi or Dutch and as i came here fort he first time i noticed that persian language were almost lost among them and all i need to do was try speak in english with them that was really weired.
The next way is to figure out more grammatical and lexical resources of our local languages , and this is only possible as we just read the artworks of our decendents and thier writings so as to find out the correct way of using the languages and sentence combination containing more classic vacabulary, to let our generation be fammiliar with those orginal words of local language, alongside the forign words entered the languages.
Finally, given that english is a global language and must be learnt through everyone, considering using local languages is also a good idea, according to me. Among thousends of ways to let a language survive I mentioned two above.
