If someday you wake up to see, 

The Mississippi flows to the north,
Niagara Falls has stopped making froth,
All the ices in Greenland have melted away,
Siberia is lush and covered with grass,
The Grand Canyon doesn't mark a chasm,
The Sahara is full of blossom,
The Himalayas has turned into a canyon,
Bengal is a land without a political opinion,

I will still be yours; you will be surprised to see.
