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.”

Switch Quotes (7 quotes)

DNA that used to have some function way back in evolution but currently does not (and might possibly be revived if, say, an ancient parasite reappeared), DNA that controls how genes switch their protein manufacturing on and off, DNA that controls those, and so on. Some may actually be genuine junk. And some (so the joke goes) may encode a message like ‘It was me, I’m God, I existed all along, ha ha.
In Terry Pratchett, Ian Stewart and Jack Cohen, The Science of Discworld (2014), 218.

Forests … are in fact the world’s air-conditioning system—the very lungs of the planet—and help to store the largest body of freshwater on the planet … essential to produce food for our planet’s growing population. The rainforests of the world also provide the livelihoods of more than a billion of the poorest people on this Earth… In simple terms, the rainforests, which encircle the world, are our very life-support system—and we are on the verge of switching it off.
Presidential Lecture (3 Nov 2008) at the Presidential Palace, Jakarta, Indonesia. On the Prince of Wales website.

It was necessary to invent everything. Dynamos, regulators, meters, switches, fuses, fixtures, underground conductors with their necessary connecting boxes, and a host of other detail parts, even down to insulating tape.

To me, it [the 1962 space flight of Friendship 7] is not something that happened a long time ago. It seems like a couple of days ago, really. It’s a rare day I don’t think about it, relive it in my mind. I can remember every switch I flipped, every move I made, every word I spoke and every word spoken to me. Clear as a bell.
As reported by Howard Wilkinson in 'John Glenn Had the Stuff U.S. Heroes are Made of', The Cincinnati Enquirer (20 Feb 2002).

We’re going to see public attitudes [on climate change] switch not in proportion to scientific findings or graphs, but in proportion to the stories they hear, the people they know whose lives have been touched by climate change or some environmental calamity. That’s what really changed public opinion.

[My grandmother] lived the latter years of her life in the horrible suspicion that electricity was dripping invisibly all over the house. It leaked, she contended, out of empty sockets if the wall switch had been left on. She would go around screwing in bulbs, and if they lighted up, she would fearfully turn off the wall switch and go back to her Pearson's or Everybody's, happy in the satisfaction that she had stopped not only a costly but dangerous leakage. nothing could ever clear this up for her.
In My Life and Hard Times (1937, 1999), 16.

[Rochelle Esposito] said that she didn’t normally interfere, but wanted to tell me that it was really risky to switch organisms before getting tenure.
Recollection in her own words, as quoted in Anna Azvolinsky, 'Fearless About Folding', The Scientist (Jan 2016).

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
