To see the effects of pollution in rivers, just have a look at the Clyde or the Thames near to the sea  and compare it with the same river a few kilometres away to the hills, before factory waste has been flowing into it.

A hundred  years ago you could catch eatable fish in rivers like the Thames and the Clyde. Now factories and homes are putting waste materials which are poisons into these rivers.

Large cities on the Great Lakes of North America are letting different wastes flow into the water. These wastes, added to the mud brought down by the rivers, are speeding up the process by which a lake becomes useless for shipping.

The Yarra River in Australia was once such a pretty place to sit beside on a hot summer day. But that’s all changed now. Factories have appeared on each side of the river and people sitting beside the river now throw their endless tins and papers into it.

Nothing can live or grow in this polluted water now.
