There was no man when I visited this earth some lackhs of years back. I met only few mosquitos and dinosaurs and few crocodiles.The planet looked so beautiful and live I decided to  make it my home.ALL creatures opposed and one mosquito even threatened me to harass for thousands of years to come. it was so tiny I ignored it and the threat.Slowly and slowly i destroyed many creatures till few species were left.I am still doing my dirty work but regret that why I left out the tiny mosquito.
