I don’t think any of the resources you’ve mentioned can be handled for unlimited population growth on Earth.
Besides that, land is a limited resource on Earth for continued human population increase, so instead of asking people to limit reproduction, we’re better off looking for different planets to inhabit.
That said, Earth is the only known habitable planet we have, and it makes sense to protect it for both practical and cultural reasons. But future gens will benefit from space exploration, it doesn’t have to be either/or regardless of what anyone says.
