To an observer situated on the moon or on one of the planets, the most noticeable feature on the surface of our globe would no doubt be the large areas covered by oceanic water. The sunlit face of the earth would appear to shine by the light diffused back into space from the land and water-covered areas.

The Earth is cylindrical, three times as wide as it is deep, and only the upper part is inhabited. But this Earth is isolated in space, and the sky is a complete sphere in the center of which is located, unsupported, our cylinder, the Earth, situated at an equal distance from all the points of the sky.

I think it's perfectly OK to exploit the moon. Largely for two reasons: there's no life there, and it is close enough and rich enough in resources to be economically useful to Earth. In the final analysis, everything we do in space, if it does not help the people of Earth, all the people, it's not going to happen.
