Even with Star Trek type technology, Earths population will never be reduced significantly through colonizing other planets.
Say One hundred million humans leave Earth every year for other planets.
that would take about 60 starships the size of Galaxy class ships leaving EVERY DAY.
Say Earth has 6 or 7 billion people on it to begin with.
Take 100 million to colonies and how many humans do you have left?
Six or seven billion. One hundred million a year, every year, for centuries won't make a dent in Earths population. A natural low birthrate will replace those 100 million and more in a years time.
And we've never seen a single indication of such a massive colonization effort by Earth. Most of the Earth colonies we've seen are actually quite small.
I don't care if we have 31st century level tech. Earths population will probably stay in the 6 to 10 billion range or higher as far as the eye can see.
