1970 World conservation（保护）year . The United Nations wanted everyone to know that the world was in danger . They hoped something could be done .
Here is one example of the problem . At one time there were 1,300 plants , trees and flowers in Holland , but now only 866 are left . The others have been destroyed by modern man and his science . We are changing the earth , the air , the water and everything around us . We can’t live without these things . If things go on like this , we shall destroy ourselves .
What will happen in the future ? Perhaps it is more important to ask “ What must we do ? ” More and more young people have known this . Many of them are helping to save our world . For example , they plant trees . In a small town in United States a large group of girls cleaned the banks of 11 kilometers of their river . Young people may hear about conversation through a song called “ no one’s going to change our world ” . It was made by Cliff Richard and other singers . The money from it will help to conserve tigers , elephants and panders on the earth .
这里是一个问题的例子。一度有1300种植物，包括树木和花卉，然而如今只有866种存活。另外的已经被现代人和科技所毁掉。我们正在改变土地，空气，水和我们身边的一切。离开以上的物质我们不能存活。如果事情仍然如此下去，我们最终会害死自己。
未来会发生什么？也许更重要的应该是问“我们必须做些什么？”。越来越多的年轻人已经懂得这个了。他们中的很多人正在帮助我们保护世界。例如，他们参与种树。美国的一个小镇，一大队女孩儿们清理的11公里的河岸。年轻人也许通过一首叫做“no one’s going to change our world ”听说保护。这首歌是由 Cliff Richard 和其他歌手制作的。歌曲的所得会帮助保护老虎，大象和大熊猫。
