Don't pull the wool over your own eyes, it's all unnatural

 Who are those cows in the shed,

 Little calves lying on the ground, 

tags in their ears

Mothers looking down

Begging

Shouldn't they be in a field?

Shouldn't they not be carolled

But we all like to drink our tea

With milk

Therefore here's a dairy herd

Who are those sheep in the field?

Can you imagine them long ago

Roaming around by themselves

No particular place to go

Ewes separated from their babies

Sadly bleating on

But we all like a lamb chop

Or a leg of mutton

Even more we are keen on a woolen jumper

To keep warm in

You can't say that these are natural

Man's dominion of nature

But we do what we can and we must to survive

Except now that threatens the planet
