I don't see a 100% future where all burning of fossil fuels will cease. But we certainly can as a species reduce that burning to a manageable level. But right now, "space tourism" is not only impractical, it won't end our burning of fossil fuels.
For right now as far as space exploration, that needs to be limited to science, not exploitation.
In theory, I'd love to see the majority of humans being able to view the planet in orbit. I do think psychologically it could imprint the notion that our only home isn't to be fought over and one we all share. But the fact is, fossil fuels are killing our planet. And I don't think it is as simple as replacing passenger jets with rockets in the same numbers.
Imagine space travel launching rockets at the same rate every day as passenger jets. It still requires burning fossil fuels in both cases. That solves nothing.
I am for space exploration. But for now, I think humanity would be better served at limiting rockets to science, not pleasure.
Space rockets don’t use fossil fuels. They never have.

Anything that creates gasses and heat and is being burned contributes.
Put fire to gas, you are creating green house gasses. It isn't just about coal or petroleum.
Rockets still create emissions.
