Knightstorm, the scarcity of water was not presented as a mere planetary phenomenon. The Federation's technology to synthesize water on board a starship was presented as something beyond Kazon technology. This is just silly. Hydrogen is the most abundant element in the Universe. If there is breathable air, anywhere, there is plenty of oxygen. To synthesize water, all you need is a match. People cannot live in spaceships without enough industry to synthesize everything we take for granted on Earth.
