《保护世界文化和自然遗产公约》 A 50-year balancing act

世界遗产50年

在1972年11月16日的《世界遗产公约》上，联合国教科文组织通过了一项国际条约，首次将自然保护和文化遗产保护的概念联系起来。世界遗产项目是由埃及计划修建的阿斯旺大坝引发的，该大坝将淹没尼罗河流域的大片地区和数千件考古珍品。

梅萨维德国家公园是普埃布洛斯祖师居住了七个世纪的地方，1978年被联合国教科文组织委员会选为首批世界遗产。

50 years of World Heritage Sites

At its World Heritage Convention on November 16, 1972, UNESCO adopted an international treaty that for the first time linked the concepts of nature conservation and preservation of cultural properties. The World Heritage Sites program was sparked by Egypt's planned construction of the Aswan High Dam, which would have flooded a large swath of the Nile Valley and thousands of archeological treasures.

Mesa Verde National Park, where Ancestral Puebloans lived for seven centuries, was among the first World Heritage Sites chosen by the UNESCO committee, in 1978.
