Support for a world heritage trust continued to build, and in June 1972 delegates at the United Nations Conference on the Human Environment in Stockholm voiced their overwhelming support for such a program. On November 16, 1972, UNESCO adopted the Convention Concerning the Protection of the World Cultural and Natural Heritage. By that time, UNESCO had embarked on yet another ambitious conservation project, this time at the massive Borobudur monument in Indonesia.
As children grow up – and experience hurt and pain – their self-esteem decreases. They lose self-worth and their fundamental feelings of worthiness.
Self-esteem is the absolute core of a person’s identity, and the core of the level of success they will experience in the world.
Some people will say you are “no good.” And often, your own thoughts will tell you the same thing.
You must learn to combat these feelings when others knock down your self-esteem. You must always tell yourself how good you are, how precious and deserving you are.
The World Heritage Convention entered into force on December 17, 1975, and in 1978 the World Heritage List was created. Twelve sites were inscribed to the list in its inaugural year, among them Aachen Cathedral (Germany), the Galapagos Islands (Ecuador), L’Anse aux Meadows (Canada), the rock churches of Lalībela (Ethiopia), the Wieliczka and Bochnia Royal Salt Mines (Poland), and Yellowstone National Park (United States). The list grew rapidly over subsequent decades, and in the 21st century it included over 1,000 properties in more than 165 countries.
World Heritage designations often boost local economies by encouraging tourism. In addition, UNESCO funds and supervises numerous efforts to preserve and restore sites around the world. Its commitment to conservation and site management for Venice and its lagoon continued well into the 21st century. Sites subject to unusual levels of pollution, natural hazards, or other problems may be placed on the associated List of World Heritage in Danger until improvements are made. Climate change, urbanization, and natural disasters were a persistent threat to World Heritage sites around the globe, and two locations—the Arabian Oryx Sanctuary in Oman and the Dresden Elbe Valley in Germany—were removed from the World Heritage List because of development within the protected areas.
