Hindu Puranas on end of life on Earth

After a drought lasting many years, seven blazing suns will appear in the firmament; they will drink up all the waters. Then the wind-driven fire will sweep over the earth, consuming all things; penetrating to the nether world it will destroy what is there in a moment; it will burn up the universe. (Vishnu Purana)

Age of destruction is so horrible that there is no rainfall for one hundred years. People have no food to eat and are compelled to eat one another. Overpowered by what is wrought by time, men gradually lead themselves to utter destruction. (Bhagavad Purana)

This seems to be a warning …the way we are destroying earth what is mentioned in Puranas is a possibility in future…
