Give Us Your Reason

The future of our world is in jeopardy
As toxic substances are made ready
Within a second to destroy the body
And in a minute you are nobody

Reproduction is in the decrease 
And death is in the increase 
Where is our human defence?
Should we destroy our own fence?

Billions are spent to build our world
But within an hour we return to the old
Is this the way we are told?
Or are we so bold?

Comeon give us your reason
As we are waiting for the lesson.
