Good Quotations: Saliva Via The Milky Way
April 26th, 2011
“The saliva in your mouth comes from the Milky Way. Saliva is 99.5 percent water. And all the water on Earth was actually formed in space, in interstellar gas clouds. And it was delivered here when the Earth was formed, or shortly thereafter, in exactly the form it’s in.”
“So all the water on Earth – the water in your Evian bottle, the water in your glass of water, the water you use to boil a pot of spaghetti – all that water is 4.3 or 4.4 billion years old. No water’s being created on Earth. No water’s being destroyed on Earth. And what that means is the whole debate about reusing wastewater is kind of silly, because all the water we’ve got right now has been used over and over again. Every drink of water you take, every pot of coffee you make is dinosaur pee, because it’s all been through the kidneys of a Tyrannosaurus Rex or an Apatosaurus many, many times, because all the water we have is all the water we have ever had.”
“And to me, that’s actually good news. Water is incredibly resilient. It’s unlike fuel or other natural resources. It can be used over and over and over again, and it emerges – except for needing to be cleaned, ready to use again – exactly as water… That’s sort of part of the magic of water, is it’s cosmic juice that came from interstellar space, which is wonderful to sort of pause and appreciate. And it’s the most resilient thing we’ve got in daily use that is in high demand.”
