Who said: “The path towards sustainable energy sources will be long and sometimes difficult. But America cannot resist this transition, we must lead it... That is how we will preserve our planet, commanded to our care by God. That’s what will lend meaning to the creed our fathers once declared.”

Circulatory Quotes (2 quotes)

For nature is a perpetuall circulatory worker, generating fluids out of solids, and solids out of fluids, fixed things out of volatile, & volatile out of fixed, subtile out of gross, & gross out of subtile, Some things to ascend & make the upper terrestriall juices, Rivers and the Atmosphere; & by consequence others to descend for a Requitall to the former. And as the Earth, so perhaps may the Sun imbibe this spirit copiously to conserve his Shineing, & keep the Planets from recedeing further from him. And they that will, may also suppose, that this Spirit affords or carryes with it thither the solary fewell & materiall Principle of Light; And that the vast aethereall Spaces between us, & the stars are for a sufficient repository for this food of the Sunn and Planets.
Letter to Oldenburg (7 Dec 1675). In H. W. Turnbull (ed.), The Correspondence of Isaac Newton, 1661-1675 (1959), Vol. 1, 366.

The Gaia Hypothesis asserts that Earth’s atmosphere is continually interacting with geology (the lithosphere). Earth’s cycling waters (the hydrosphere), and everything that lives (the biosphere). … The image is that the atmosphere is a circulatory system for life’s bio-chemical interplay. If the atmosphere is pan of a larger whole that has some of the qualities of an organism, one of those qualities we must now pray for is resilience.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
