WORLD WITHOUT POLLUTION

I close my eyes and imagine a world without any kind of pollution. No contaminated air to inhale.Pure and fresh water, clear like mirror,green lands colored with beautiful beads of  wild life and the clear and bright azure sky.Birds scattered on sky like kites.No unpleasant smell just the fragrance of rose,lilies,jasmine and many more. No irritating lights but the guiding light of northern star,moon and fireflies. No damn noise but the sweet lullaby of nature. A paradise. A only word came to my mind I wonder that our world was ever like this or this is only my fantasy...... A fool's dream..
