What are the major factors responsible for the loss of historians monuments?

The loss of historical monuments is primarily driven by urbanization, which often leads to demolition or neglect of sites in favor of new developments. Environmental factors, such as climate change and natural disasters, also contribute to deterioration. Additionally, political instability and conflict can result in intentional destruction or lack of funding for preservation efforts. Finally, inadequate maintenance and awareness can further exacerbate the decline of these cultural heritage sites.
