There are many unique and precious places in the world.
Some of them are selected as World Heritage sites.
They are not selected for their own Heritage countries.
They are for people all over the world.
There are three types of World Heritage sites - natural, cultural, and mixed.
The selection standards were decided at the UNESCO General Conference in 1972.

How was your vacation in Australia, Meg?
It was great!
I went to a World Heritage site, the Blue Mountains.
Oh, are they listed as a natural heritage site?
Yes, they are.
Why are they called "blue"?
The mountains look blue because of an oily mist from the eucalyptus leaves.
Eucalyptus leaves? The koalas' favorite?
Yes. There are great eucalyptus forests.
The natural beauty is preserved there.
