Will God curse the earth?

Will God curse the earth?
Well, maybe, if he gets mad again.	No, he'll never do it again.
Malachi 4:6 And he shall turn the heart of the fathers to the children, and the heart of the children to their fathers, lest I come and smite the earth with a curse.	Genesis 8:21 And the LORD smelled a sweet savour; and the LORD said in his heart, I will not again curse the ground any more for man's sake.
