A now-famous 1972 photo of Earth taken by Apollo 17 astronauts from 45,000 kilometres away became known as “the blue marble”. The late scientist Carl Sagan described a 1990 picture taken from six billion kilometres away by the unmanned Voyager 1 as a “pale blue dot”.
The vision of Earth from a distance has profoundly moved pretty much anyone who has ever seen it. “When we look down at the earth from space, we see this amazing, indescribably beautiful planet,” International Space Station astronaut Ron Garan said. “It looks like a living, breathing organism. But it also, at the same time, looks extremely fragile.” Referring to the atmosphere, Garan added “it's really sobering … to realize that that little paper-thin layer is all that protects every living thing on Earth.”
Many astronauts report a deep feeling of connection that transcends borders and worldly conflict —referred to by some as the “overview effect”. Apollo 14’s Edgar Mitchell said, “You develop an instant global consciousness, a people orientation, an intense dissatisfaction with the state of the world, and a compulsion to do something about it. From out there on the moon, international politics look so petty.”
How can anyone who has even seen a photo of the Earth treat our small blue home with disdain and carelessness? How can anyone fail to recognize how precious and finite the resources, especially water, are — and that we must share and care for what we have?
The “blue marble” photo from Apollo 17, the last manned lunar mission, catalyzed the global environmental movement. Now, as people around the world compete for air, water and land — not just with each other, but with corporations bent on profit at any cost — we need a resurgence in action to care for our small blue planet.
That’s why I’m about to embark on what will likely be my last national tour. From September 24 to November 9, I’m crossing the country, from St. John’s, Newfoundland, to Victoria, B.C., with 20 stops along the way. The plan is to work with Canadians from all walks of life to protect the people and places we love. It’s the most important thing I’ve ever done.
