There is a blog called, 'Do the Math' by Tom Murphy. The idea was to take our current energy requires of Earth and extrapolate it at the current 3% year over year growth. I believe it is by the year 3,400 we would use all the energy of the Milky way. The idea was to prove that we cannot grow forever, because in 1,400 years we would somehow use all the energy of a space 100,000 light years across. Good luck with that.

Space is is just so astoundingly empty. Here in Melbourne, Australia we have a scale model of the solar system.

The Sun is about the size of a Fridge. Pluto is 9KM (5.6 miles) away and the size of a pea. Walking that really puts it all into a tangible scale. And that is merely 5.5 Light hours at full scale. Space is HUGE!

That's why I'd imagine they have rules about habitable planets in the galactic federation. You can't just go around landing on habitable planets and turning them into overpopulated toxic dumps after 300 years and repeating that exponentially. It's just not allowed. If it was, earth would have already been trashed by other E.T races thousands of years ago.

“Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.”
