Heritage is our legacy (遗产) from the past, what we live with today, and what we pass on to future generations. Our cultural and natural heritage are both irreplaceable (无可取代的) sources of life and inspiration. Places as unique and diverse as the Pyramids of Egypt, the Great Barrier Reef in Australia and the Great Wall of China make up our world's heritage.

The United Nations Educational, Scientific and Cultural Organization (UNESCO) seeks to encourage the identification, protection and preservation of cultural and natural heritage around the world  considered to be of outstanding value to humanity. This is embodied in an international treaty called the Convention Concerning the Protection of the World Cultural and Natural Heritage, adopted by UNESCO in 1972.

How does a place become a World Heritage Site? It takes a lot of people to decide.

1)If a country wants one of its places to be on the World Heritage List, it has to ask UNESCO. The place must be important and special. UNESCO put the Great Wall on the list in 1987 because, it said, it was a great part of Chinese culture and beautifully made to go with the land. When a country asks, it must also make a plan for taking care of the place.

2)The World Heritage Committee of UNESCO talks about different places and decides whether to put them on the list. The committee meets every June. Many experts help the committee to decide.

3)After a new place goes on the list, UNESCO gives money to help keep it looking good. If a place is in serious danger, it may be put on the List of World Heritage Sites in Danger. UNESCO gives special care and help to those places.

4)Countries have to give UNESCO regular reports about places on the list. If UNESCO thinks a country isn't taking good enough care of a place, the site will be taken off the list.
