“Without the CO2 we’d all be dead”

I heard some of the speeches at the rallies and thought them a bit technical. I think we need simpler messages, so to give it a go I wrote the following poem – a bit of doggerel to re-inforce just one point.

Photosynthesis

CO₂ and H₂O and sunlight
Are the reason we can eat our daily bread
CO₂ and H₂O and sunlight
Without the CO₂ we’d all be dead

For plants store energy by making sugars
And other foods that bring us great delight.
It’s the basis of all life upon the planet
CO₂ and H₂O and light

Photosynthesis is what they call it,
Photo puts the emphasis on light
Synthesis means putting it together
CO₂ and H₂O and light.

The lion has an antelope for breakfast,
and the antelope, before his final fright,
Ate grass, which like all other vegetation,
Fixed CO₂ and H₂O and light.

The mighty whale eats krill to keep its weight up,
And the krill eat tiny plants, near out of sight,
And the tiny plants create the basic food store
From CO₂ and H₂O and light.

The food chain can be very complicated
With formulae to give a student fright,
But the basis of the chain is very simple –
It’s CO₂ and H₂O and light.

Now some say CO₂ is a pollutant,
A poison we must always try to fight
But remember if you want to go on living –
You need CO₂ and H₂O and light!

CO₂ and H₂O and sunlight
Are the reason we can eat our daily bread
CO₂ and H₂O and sunlight
Without the CO₂ we’d all be dead
