Happy Earth Day
Happy Earth Day, from the International Space Station.
Here's something to think about. This video is taken from a spaceship, the ISS. The astronauts aboard have to carefully regulate their environment to keep it habitable, safe for human life.
Now, here's the thing. You're on a spaceship too, Spaceship Earth, our one and only biosphere. The International Space Station orbits Earth at around 15,000 miles an hour. Earth's rotational speed is around 1,000 miles an hour but Earth, in its orbit around the Sun, travels at nearly 67,000 miles an hour. And our galaxy itself travels through space at 490,000 miles an hour. In other words you are moving through the universe at over half a million miles each and every hour.
Yep, we're all passengers aboard a spaceship and, like those astronauts, we too have to carefully regulate Earth's environment to keep it habitable, safe for human life. Don't you think we've got a bit of catching up to do?
