There are many historical sites and places in the world that give us insight and evidence of the past civilization. These sites help us learn about our ancestors, their living and culture. These sites can be called common or universal heritage (遗产) of humankind and our world heritage.

These sites from the past civilizations are for all humans. We must live in them today and also pass them on to future generations. They teach us about our past and represent the great achievements of our ancestors and make us proud. World heritage has historical, cultural and economic significance. It has exceptional value and importance for humankind from history, science and arts points of view and must be cared for.

Many UNESCO sites that stand today are under threat. There is a list of thirty sites by UNESCO that are endangered. There are many external factors responsible for damaging the world heritage, some of which are climate change, natural disasters, urbanization and unchecked tourism etc.

With the growing strength of these external factors, it is becoming more and more important to take proper measures to save and preserve these timeless achievements of humankind. There are many communities and organizations in the world which are working to protect these sites. We can work with these organizations, travel agencies, government groups and local communities. We should join them to support their cause. Another way to play our part is to shoulder travel responsibility Tourism can generate funds for the restoration of historical sites but at the same time unchecked tourism can damage them seriously.

The younger generation must preserve the identity of the people who came before them. No matter what is our reach, we should help protect them through effective means. Our every step would count and help in protecting the world heritage sites.
