>You can't recycle to infinity.
The lifespan of the earth is not infinite, pretending it is is foolish. We have about 5 billion years on earth before it will be consumed by the sun. Presuming an infinite earth creates a very obvious, simple, and wrong conclusion about something that is actually very difficult problem.
>The logical conclusion is that at some point we run out of resources.
The point of renewable resources -- like solar -- is exactly that they are renewable or effectively infinite.
You’re not really addressing the obvious though: that at the rate that we are consuming and polluting the earth, we could be pushing ourselves into extinction faster than the sun could just naturally swallow up the earth. I don’t think anyone is debating this eventual death of our star, but our astronomers would very much like to live long enough for us to find another home planet and develop the technology to get there.
