I heard on the news a certain world leader doesn’t think carbon monoxide is bad for us. The Meritorious Professor Causan has a theory that for every action there is an effect e.g inhale enough poisonous gas and you will die, this is now known as the Causan Effect. So follows is an experiment to prove the theory, I strongly suggest that, that certain world leader should try 

The Causan Effect

Stick a pin your finger see how it stings
Pinch you arm see what pain it brings
Poke yourself in the eye then shout ouch
Drink too much go lie on you couch

If lowering carbon monoxide is not your ambition
Sit in your car turn on the ignition
Park it in a the garage shut the doors
Press the accelerator down to the floor

Sit nice and cosy, maybe count all your money
Don’t get too worried if your head starts to feel funny
When you’ve sat there for an hour or so and had your fill
Come out and tell me carbon monoxide doesn’t kill.

All words Meadowhead Bard.
