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.”

History Of The Earth Quotes (3 quotes)

That radioactive elements created by us are found in nature is an astounding event in the history of the earth. And of the Human race. To fail to consider its importance and its consequences would be a folly for which humanity would have to pay a terrible price. When public opinion has been created in the countries concerned and among all the nations, an opinion informed of the dangers involved in going on with the tests and led by the reason which this information imposes, then the statesmen may reach an agreement to stop the experiments.
In 'Excerpts from Message by Schweitzer', New York Times (24 Apr 1957), 4, translated from a letter issued by Schweitzer through the Nobel Committee, asking that public opinion demand an end to nuclear tests.

We may affirm of Mr. Buffon, that which has been said of the chemists of old; though he may have failed in attaining his principal aim, of establishing a theory, yet he has brought together such a multitude of facts relative to the history of the earth, and the nature of its fossil productions, that curiosity finds ample compensation, even while it feels the want of conviction.
In History of the Earth and Animated Nature (1774, 1847), Vol. 1, 73.

We may therefore say in the future, strictly within the limits of observation, that in certain respects the fossil species of a class traverse in their historical succession metamorphoses similar to those which the embryos undergo in themselves. … The development of a class in the history of the earth offers, in many respects, the greatest analogy with the development of an individual at different periods of his life. The demonstration of this truth is one of the most beautiful results of modern paleontology.
Carl Vogt
From Embryologie des Salmones, collected in L. Agassiz, Poissons d'Eau Douce de l’Europe Centrale (1842), 260. Translated by Webmaster using Google Translate, from the original French, “On pourra donc dire à l'avenir, en restant rigoureusement dans les limites de l'observation, qu'à certains égards, les espèces fossiles d'une classe parcourent dans leur succession historique des métamorphoses semblables à celles que subissent les embryons en se développant … Le développement d’une classe dans l’histoire de la terre offre, à divers égards, la plus grande analogie avec le dévelopment d’un individu aux différentes époques de sa vie. La démonstration de cette vérité est un des plus beaux résultat de la paléontologie moderne.”

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
