Too many old buildings are in danger and destroyed in many countries. What are the main reasons? How it can be protected.

As modernization is taking place identity of ancient buildings has been fading, which also threatens nation's beauty. It is considered some of the human activities are responsible for this issue; however, it can be ameliorated with viable measures. The first and foremost trigger behind this is migration. Increasing job opportunities and advance amenities allure population towards other nations, where ancient buildings have to pull down in order to accommodate migrated people. To cite an example, Canadian government is providing several facilities not only to its natives, but also to whom are residing temporarily, thereby, Canada is replacing all buildings with new one to provide them shelter. Can this problem be solved? certainly, yes if government impose penalty on those committees who are accountable to make harm to these premises, will obviously help to preserve these. Besides, industrialisation has also become a cause of demolition of ancient buildings since, unemployment has been rising in every underdeveloped country, where merely Industries have remained a last option with a view to balance employment; therefore, old buildings are being destroyed to construct more manufacturing units. As per survey conducted by 'home ministry' reveals that in Europe, 39% of medieval skyscrapers were pulled down so as to build Steel Industries. To curb this, constructors should be apprised how important these buildings are for the culture of the nation and also to be suggested to build it far from the city centres without making harm to existing ones. To conclude, although burgeoning pace of migration and industries leads to destruction of historical buildings, yet it can be prohibited by means of government's endeavour by penalising those, are accounted for.
