We are the bald monkeys,

We are the bald monkeys,
From a planet in the milky way.
We rush around in our tin cans,
From place to place to place.
We can make machines of wondrous power,
And also vast heaps of trash.
We'll kill wild forests and elephants,
We'll turn our planet to ash.
We are such curious creatures,
We always want to know, 
So we cut others up to see how they work,
And when they're dead  we know.
We think that we are so intelligent,
But don't seem to realise,
That there is no planet b
For us to colonise.
So unless we treat earth and it's life,
With care and with respect,
The oceans will rise and erase us,
As a failed experiment.
