A Walker in the Suburbs

My classes are winding down. The final projects await, looming like giant icebergs on the horizon, but I can count remaining class meetings on the fingers of one hand. Which gave last night’s words the ring of finality.

We were talking about the responsibility the Global North has for the Global South. We might think it’s not our problem if climate change drives residents of densely populated, low-lying Bangladesh to leave their homes and families. But these people must go somewhere.

None of us brought up the meeting taking place in Azerbaijan even as we spoke. But COP 29, the United Nations climate change meeting, is in its final days and there is still much work to do. How will developing countries help less developed ones?

Most of the migrants in this world are from places where weather, hunger and civil unrest are driving from their homes. We can’t think all of this is someone else’s problem, the professor said. Meaning we’re all in this together. Meaning it’s a smaller world than we might think.

It’s a frightening thought … but also an exhilarating one.

By now most of us recognize the Blue Marble photograph. Even if we don’t know it’s called the Blue Marble photograph, we’ve seen this picture.

It was a meta moment for our planet, as the Apollo 17 astronauts looked out their window and snapped a shot of our globe floating like a blue-and-white dream in a sea of darkness. The first time Earth was viewed from space.

What I didn’t know, but only learned by reviewing a new book, is that the raw image originally submitted to NASA placed the southern hemisphere at the top of the frame. (Those weightless astronauts didn’t know which way was up!) NASA flipped the image before releasing it to the public. It would have been mind-bending otherwise.

To learn why North landed on top, you’ll need to read the book. But isn’t it interesting to ponder a world where what’s up is down and what’s down is up? Kind of puts us in our place, doesn’t it?
