"We went to the Moon, and we discovered Earth. I claim we discovered Earth for the first time. How does that affect culture? I got a list! The instant that photo comes out, THAT is the identifying cover picture of The Whole Earth Catalog, thinking about Earth as a whole. Not as a place where nations war, as a whole. 1970: The Comprehensive Clean Air Act is passed. Earth Day was birthed March, 1970. The Environmental Protection Agency was founded in 1970. The organization Doctors Without Borders in 1971. Where do you even get that phrase from?! No one thought of that phrase before that photo was published. Because every globe in your classroom has countries painted on it. DDT got banned in 1972. We're still going to the Moon; we're still looking back to Earth. Clean Water Act, 1971. 1972: Endangered Species Act, the catalytic converted gets put in in 1973, unleaded gas, 1973. We're still at war in Vietnam, there's still campus unrest, yet we found the time to start thinking about Earth."
"The photo of Earth rising over the lunar landscape, we all know it: 'Earthrise Over the Moon.' There was Earth, seen not as the mapmaker would have you identify it. No, the countries were not color-coded with boundaries; it was seen as nature intended it to be viewed. Oceans, land, clouds. We went to the Moon, and we discovered Earth."
