" "When too much cynicism threatens to engulf us, it is buoying to remember how pervasive goodness is.
Carl Edward Sagan (9 November 1934 – 20 December 1996) was an American astronomer, planetary scientist, cosmologist, astrophysicist, astrobiologist, author, and science communicator. His best known scientific contribution is research on extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation. Sagan assembled the first physical messages sent into space, the Pioneer plaque and the Voyager Golden Record, universal messages that could potentially be understood by any extraterrestrial intelligence that might find them. Sagan argued the hypothesis, accepted since, that the high surface temperatures of Venus can be attributed to, and calculated using, the greenhouse effect. He testified to the US Congress in 1985 that the greenhouse effect will change the earth's climate system.

We all have a tendency to succumb to a state of despair about the destructiveness and shortsightedness of the human species. I've certainly done my share (and on grounds I still consider well-based). But one of the discoveries of my illness is the extraordinary community of goodness to which people in my situation owe their lives.
There is in the lovely Martian landscape not a footprint, not an artifact, not even an old beer can, not a blade of grass, not a kangaroo rat, not even, so far as we can tell, a microbe. Mars and the Moon and Venus... the only planets that we've landed on—are utterly lifeless. ...in our solar system we may discover that there is life only on this world. This says that life is not guaranteed, that life requires something special, something improbable.

The school systems, it seems to me have a attitude of discouragement of asking fundamental questions, if a 5 or 6 year old asks why the moon is round or why the grass is green? The usual adult answer, at least in my experience is to discourage the child.
what color did you expect the moon to be? square? what color you expect the grass to be?blue?
Instead of saying that those are interesting questions and lets try to find the answers or maybe nobody knows the answers and when you grow up you would be able to discover the answers.
It would be very healthy for human species if we could have less discouragement and more scientists.
