UNESCO World Heritage Sites
Heritage is not only our legacy from the past.It is what we live with today,and what we pass on to future generations.Since 1975,the United Nations Educational,Scientific and Cultural Organization,or UNESCO,has maintained a list of World Heritage Sites.These are places of great cultural or natural significance,and they are protected by law under an agreement amongst most of the countries of the world.
World Heritage Sites are classified as cultural heritage,natural heritage,or mixed heritage. A mixed heritage site is a site that has both cultural and natural significance.There are more than eight hundred Cultural World Heritage sites.Of these,perhaps the best known is the Giza Pyramid Complex,a site located just outside modern-day Cairo.As the name suggests,the site is famous for its pyramids,especially the Great Pyramid,which was built by the Egyptian ruler Khufu over 4,500 years ago.The complex is also famous for the Great Sphinx,a huge and somewhat puzzling sculpture with the body of a lion and the head of a man.The Great Pyramid was famous even in ancient times,and is the only one of the Seven Wonders of the Ancient World still in existence today.
Natural World Heritage sites protect areas of outstanding natural beauty and habitats for endangered species,although unfortunately at present they cover less than one per cent of the Earth's surface.One such site is Lake Baikal in southern Siberia.Lake Baikal is deepest lake in the world.Amazingly,it also contains twenty per cent of the world's total unfrozen fresh water.Lake Baikal is home to many unusual life forms,and is of great scientific importance.
There are over thirty Mixed World Heritage sites,a number of which are in China, including Mount Tai,Mount Huang,Mount Wuyi and Mount Emei.Mount Tai is known as the Eastern Mountain of the Five Great Mountains of China.Seventy-two of China's emperors are said to have visited it.The natural beauty and the rich culture of the mountain have been sources of inspiration for writers and artists over the centuries.World Heritage sites belong to all the peoples of the world,but some are now under threat from human activity and the effects of climate change.Only a greater awareness and appreciation of World Heritage sites can ensure that we continue to protect them and pass them on to future generations.

Saving the Reef
With so much to see in the crystal-clear waters of Australia's Great Barrier Reef,it's no wonder that millions of people visit it every year.In addition to tourism,it is a major site for fishing,research and shipping.Yet more than half of the reef's coral has been lost since 1985,and human activity is largely to blame.
Industry along the coast pollutes its waters,while illegal fishing is reducing the number of fish.But the biggest threat may be climate change caused by human activities.Rising water temperatures bleach the coral,not only causing it to lose its rainbow colours,but killing the algae it needs to survive.Climate change is also making the water more acidic,causing coral to grow more slowly.
Fortunately,long-term plans are now in place to try to combat the effects of climate change. The reef became a UNESCO World Heritage Site in 1981,and today is carefully monitored. Areas of the reef where living things reproduce are now protected,and measures are being taken to stop tourists and fishing boats damaging the reef further.The islands around the reef are also protected from fire and pests.Through actions such as these,it is hoped that the Great Barrier Reef will be conserved for future generations.
