From the air they softly suck the gas
That, one day, could kill us all.
Unseen, their chloroplasts
Surge and jostle to catch the sunlight:
Microscopic power stations
Blanketing the world,
Making fuel enough
To heat, light and move us
Six times over, while emitting only
The elements of life itself.
In due season
They seduce our senses courting bees
Then freely let their future fall
Into our waiting, hungry hands.
They have no voice
But that the breeze bestows;
No locomotion of their own, yet set
The earth itself astir,
Heaving, splitting – and, when they are gone,
Surrendering to gravity,
Water and the wind.
Without them, we would suffocate,
Starve, sleep unsheltered, till
We stumble to a sweating, shivering end.
This we know
In labs, the white-coats burn through time and millions
In their attempts to do what Nature
Cracked a billion years ago.
While she continues, quiet and unremarked,
In every leaf and blade of grass.
Inspired by last night’s BBC documentary Botany – A Blooming History. Photosynthesis is so easy to take for granted, yet it’s the most fundamental process on earth. During the programme, they showed some leading-edge research being done at the University of Glasgow that’s aiming to reproduce photosynthesis in the laboratory. It’s important work, potentially unlocking unlimited sources of free, clean energy. The scientists are using electricity, platinum electrodes and all kinds of complex apparatus to separate water into its constituent elements, hydrogen and oxygen. Something the humblest plants have been doing, using nothing but sunlight, for a thousand million years, and we’re still decades away from fully understanding, let alone copying.
