Plastic

If I find a time machine, the very first thing I want to do is : travel back into time and undo the very invention of Polyethene. This is the most dreaded substance every invented that will someday wipeout life from earth. It is not nuclear catastrophe that is going to put life off on earth, rather we will be soooooo much covered by plastic that it will hurt living.
Like the frog sitting in water that is warming up, we are waiting for our end through this most used poison.
Let us wait, till there is nothing to wait except for plastic graves.
