Question

is our reponsibility to preserve our indegenous culture

Answer 1

We have many duties and responsibilities towards our country and nation. But, if the topic goes on to about preserving our Bengali or Indian culture, I think absolutely, yes. And when that our culture is so significant and dignified, why will we not take this matter into our hands, as our most important responsibility? 
But, it may be easy for most of us to say but in reality, instead of preserving our culture rather, we just destroy it by mixing it with foreign cultures.
But it is so not our faults, in the modern world and technology there are many inventions that are not improving our lives, but rather just only baffling our individual cultures.

Like, T.V., it is the best example and the main cause for this. T.V is good as it may show some good,educational and learning channels, as I am not denying this statement. But there are some foreign channels that are destructing or causing destruction to our prestigious culture. For example, some foreign channels have scenes, which does not go or is not suitable for or culture. For this, many girls,boys, women and men are wearing foreign dresses and following foreign recipes, which destroys our culture and in reality makes us a fool and loser of us, for that country's culture we are following.

So, my conclusion is that, we should stop following others cultures like fools and, start preserving and conserving it. Furthermore, the government must also take necessary steps  to strengthen this issue, further. There are atleast billions and trillions of people in the world.
We so many people are from individual countries and nations and for that we have individual rules, that is our culture. So, if we follow others culture, then our culture will be not ours. We should raise our head high and say -
WE ARE FROM OUR OWN COUNTRIES AND, WE ALL FOLLOW OUR OWN CULTURE AND TO CONSERVE OR SAVE IT, WE CAN DO ALMOST ANYTHING.
