World monuments in Danger Acid rain is rain that contains particles of acid.0:18
It is mainly caused by burning fossil fuels.0:31
Acid rain is bad for the environment and many of the world's historic monuments are being damaged by it.0:35
The Statue of Liberty in New York was a gift from the French people to the American people and is a universal symbol of freedom and democracy.0:42
Millions of people visit this great monument every year.0:51
For many years now, acid rain has been damaging the statue and has even changed its color.0:54
The Lishan Giant Buddha is located on the eastern side of the Ming river in the Sichuan Province of China.1:01
It is 70.7 meters high.1:08
Begun in 713 AD and finished in 803 AD, the statue took people around 90 years to carve from stone.1:11
It is the world's largest stone buddha.1:20
It was nearly destroyed by wind, erosion and acid rain before 1963, when the Chinese government began to repair it.1:23
Nowadays, the maintenance work is still in progress in an effort to restore this beautiful monument.1:31
The Great Sphinx in Giza is one of the most fascinating historical monuments of all and a national symbol of both ancient and modern Egypt.1:38
It was built about 4,500 years ago and is the biggest stone sculpture ever made.1:47
Every year, millions of tourists come to see the Sphinx.1:53
Unfortunately, wind, smog and acid rain are putting this wonderful monument in danger.1:57
If we want to reduce acid rain, we must burn less fossil fuels.2:04
Burning coal, oil and gas releases huge amounts of sulphur into the atmosphere.2:08
This is what creates acid rain.2:14
The best way to solve the problem is to use alternative energy sources to produce our electricity.2:16
Factories which use solar and wind power instead of the traditional fossil fuels can really help the environment.2:23
Another thing we can do is make cars and other vehicles more environmentally friendly.2:30
We need to stop using petrol.2:35
Instead, we can use cars that are electrically powered or run on some other fuel.2:37
In this way, the atmosphere will be cleaner and our monuments will stay beautiful.2:42
