LET’S MEET the commuters of London Town
But not the humans of dubious renown
Who flood daily across the capital
With faces pale and without committal
Congesting the town with cars and scooters
Carbon spreading, such bad commuters.
Stop now for once and clear your mind
To thank commuters of a different kind
Though to see them there is no hope
Without a hugely enlarging microscope
Showing trillions of critters small and scaly,
Vertical commuters, who twice daily
Rise to the surface looking like slime
But photosynthesise in Mission Sublime
Providing oxygen from the Thames brine
Helping to offset the City’s decline
Which could have become even more tragic
But for the Thames and its foreshore magic
