I see the switch to methane as part of a sea change in the launch industry. Part of the realisation that hydrogen sucks as a first stage fuel, which is significant because NASA in particular were fixated on it for decades (and still are for SLS). Part of the New Space willingness to rethink old assumptions and ways of doing things. The switch is a symptom rather than a cause, but still a sign of the times.

The Caspian Sea. Once it was the 4th largest body of fresh water in the world.

Now it has been badly shrunken and is very polluted and becoming too salty to support life and it isn't the only lake.

The Great Salt Lake and the Dead Sea are vanishing. Of course, that water could not be used for anything but, the winds blow and blows the salt across cities and agricultural lands.

The water does not always make it way back.

That is really bad for agricultural land, killing it off and increasing the problems.

Ocean life is struggling now, reefs are dying, fish stocks depleted. Now you want to increase the amount of salt.

Anyway, I can see if being able to get ice from other planets and finding a way to process it could be helpful in future space stations and exploration.

Even if my opinion is the dumbest thing you have ever read, I thank you for the informed conversation.
