The Once Great River Poem by Francis Duggan

In the once great river pollution is rife
Nowadays it does not support much aquatic life
In a polluted river fresh water fish rare
Pollution can cause extinction of that much we are aware
On the polluted river few water birds to be seen
Most of the river pools covered in algae of green
From sewage and wash of chemical fertilisers that in drains into it does flow
With so called human progress the scourge of pollution does grow
Pollution in it flowing to the distant ocean shore
The once great river is not great anymore
Do not drink of these waters the warning signs say
Pollutiuon is rife in the World of today
And the once great river flows on muddy gray
To the mighty ocean many miles away.
