DAVID TODD- WHERE WE GOING TO GO -

They came in the night and they came in the day

They came until they took it all away

And all they left was a barren ground

Where no life can be found

They didn't give a reason and they didn't say why

Millions of trees had to die

In the name of progress was all they'd say

Step aside and get out of our way

• What I want to know is where we gonna go

When the rain don't make our garden grow

And the soil's too dry for the seeds to sow

How long till we learn

You play with fire and be sure to burn

A one way ticket with no return

Cause where we gonna go

Well I don't know

• They tell us technology is a wonderful thing

• Not to mention the destruction it brings

• One step forward and two steps back

• Go from the light and into the black

• They feed us with lies and treat us like fools

• But don't stop to realise its a game we all lose

• On a road to self destruction with every step we take

• Like a ship sinking fast and• no escape

• What I want to know is where we going to goWhen the sun’s threat to all belowAnd our pollution stops our rivers flowIt’s time you and me take responsibilityIt’s a fragile world in dire needCause where we gonna goWell I don't know

Spending money to find life on Mars

It doesn't make any sense to me

Like trying to live at the bottom of the ocean

Some things are not meant to be.

• What I want to knowIs where we going to goWhen the ocean rise and the strong winds blowAnd the temperature melts the ice and snowNot time to waitIt won’t be long and it will be too lateIn this together and we are all at stakeCause where we gonna goWell I don't know
