Pretty cynical corpo-ambiguity-speak, even by Musk standards.
We're supposed to be happy they're promising not to develop one-hundred percent of the land footprint? They will leave at least 0.00001% of land area as wetlands and therefore we oughta be happy?
Such empty bullshit it's more insulting they even put an environment-leaning section on the site. Just say "fuck it, our space fetish is more important than the wetlands."
