Water is our life source. It makes up 70 per cent of bodies, and the average person actually spends 18 months of his life the bath or shower.
But we are only now learning how to look water. Acid rain polluted as many as 18,000 lakes and our seas and rivers are polluted with waste products. It is now expensive to try to repair the damage which has been done. We have some hope for the future, though, new sources of water have been discovered. People in the Sahara Desert have fish swimming in deep underground streams. Scientists also believe is a huge lake underneath London. If we have anything from our mistakes, we will try to keep these new areas of water clean.

Robert Burns, also known familiarly as Rabbie Burns, the National Bard, Bard of Ayrshire and the Ploughman Poet and various other names and epithets, was a Scottish poet and lyricist. He is widely regarded as the national poet of Scotland and is celebrated worldwide. He is the best known of the poets who have written in the Scots language, although much of his writing is in English and a light Scots dialect, accessible to an audience beyond Scotland. He also wrote in standard English, and in these writings his political or civil commentary is often at its bluntest.
