As long as we have air and water (i.e. as long as we're alive), then we can make propellants such as Methane or Liquid Hydrogen and LOX, Hydrazine & Dinitrogen Tetroxide (or Hydrogen Peroxide).

- HarHarVeryFunny 1y agoWhat has that got to do with energy dense rocket fuels for getting to orbit ?!
- macintux 1y agoThe key phrase was "successor civilization".
- crazygringo 1y agoSo? We build nuclear power plants and it's not exactly easy/efficient to extract uranium. Hard things are done all the time. Having coal/oil is pretty irrelevant in terms of whether a civilization can build spacecraft.
- macintux 1y ago"and when we drain the planet dry of easily-accessible fossil fuels we’ve deprived any successor civilization of its opportunity to escape the planet." Successor. Whoever comes along after we've done ourselves in.
- crazygringo 1y agoHuh? "We" is the human race, whatever civilization. What point are you trying to make? What I said stands, exactly how I said it.
