>You're moving the goalposts on land area.

How am I moving the goal posts? I literally started out saying it's a fixed resource and the only way to increase is to colonize space. Your response is "but we can use more of it than we're using today" - sure, but it's STILL a fixed resource. We can move portions of it from one place to another. We can come up with creative solutions to utilize more of it than we are today. NONE of that changes the fact it's a fixed resource, and if/when we happen to use or destroy it all, it isn't magically going to create more on its own.

>We're so far off using anywhere near all of even the easily available natural resources on Earth that considering it as a limited quantity is fatuous.

*In your lifetime. If you look at the rate of development and destruction caused by humans, to claim we'll NEVER do it is RIDICULOUS. We'll never destroy the rainforest. We'll never take down all of the california redwoods. We'll never kill all of the bison roaming the plains of the midwest. We'll never... Sorry that I'm concerned for my great grandkids (if I happen to have any) and the generations beyond those, not to mention the entire human race. My purview of the world doesn't begin and end with me.

>Desalination for potable water includes filtration which removes microplastics along with everything else.

Uhh, no. The current method of removing microplastics from seawater includes using chemicals that are deadly to humans. Potable desalinated drinking water includes our tiny friends.
