"To waste, to destroy, our natural resources, to skin and exhaust the land instead of using it so as to increase its usefulness, will result in undermining in the days of our children the very prosperity which we ought by rights to hand down to them."~ Theodore Roosevelt (Message to Congress, Dec. 3, 1907)
There have been several earth like planets discovered so far. Since meteors contain massive amounts of water it is a fact that even Jupiter's moon have water, Mars had water and since meteors full the universe water exists everywhere and what little microbes of life live in that water???? It is only a matter of proximity to a star that gives life like Earth a chance elsewhere.
To think that our planet is the only one that contains life the universe is not only naive but also arrogant.
