Zubrin citisism

Zubrin's jump for Mars is more like Mao's great leap forward rather
than a small step for mankind.

Space Island's give us the room for humanity to frow within our
grasp.

The moon is a source of raw materials, like asteroids, with which to
build those islands. Mars is a waste. Too much gravity to make any
mining affordable. Not enough to sustain atmosphere or human beings.

I believe our steps should be practical ones. Spacie SIlands give us
Endless Space. Mars is too limited.
