Secondly step to Australia: the Great Barrier Reef is the world’s biggest coral reef. As the UNESCO site mentions about: The Great Barrier Reef is a site of remarkable variety and beauty on the north-east coast of Australia. It contains the world’s largest collection of coral reefs, with 400 types of coral, 1,500 species of fish and 4,000 types of mollusc. It also holds great scientific interest as the habitat of species such as the dugong (‘sea cow’) and the large green turtle, which are threatened with extinction. But in connection with global warming the temperature of the sea is getting higher and also pollution endangers the reefs.
Thirdly let’s jump into Africa. It was shocking for me that only 50.000 lions living free in Africa. The typical reasons are farmers’ attitude. They need more pastures and they hunting the lions. But they kill them indirectly too: when they get a new pasture, the animals which can be food for lions (buffalo, antelope, gazelle, etc) must leave the place (or die of hunger). Illegal hunting is also dangerous for lions.
And the last one is a building: Taj Mahal. Every day thousands of tourists visit this monument, they touch the walls and their breathe is dangerous for those old walls but also acid rain is a big problem in that area.
