I feel strongly that we should have a knowledge transfer exercises on the heritage preservation as "one world" concept. People should share insights and be responsible for their neighbourhoods on global scale.
I also feel the same need to create a common platform for all the nations, where they can stand for the preservation of cultural heritage irrespective of nation bias or discrimination.
It is the heritage of all humans no matter which country it resides in. after all many countries as political construct. Therefore it should be preserved for future generations to learn from the past
Of course, it is everyone's responsibility regardless of who it is, but also to train and aid locals and institutions to properly care for their own heritage. To do this is, however it is necessary to confront religious extremism and xenophobia.
