Children are te most valuable asset for us. We must care about them and the environment they will live in when we die.
The world is heading in one direction seeing all the signs on Earth. Polution, forest devastation, wars, crimes, politics...we have to protect our children from those.
It means we have to do it quickly. The race for wealth cannot be won by anybody if the world is poluted and contaminated. We cannot take more.

In the first version that you can find on our album there is more text than in the video version. It tells about aliens visiting us on Earth after many years. 
Our children will welcome them in future and ask them for saving the world we poluted and devastated.
They will understand it as a good sign for mankind and help us.
