You can care about humanity without needing to want to have kids. Why are we acting like everyone's lifestyle preferences are of paramount importance to everyone else's existence? OP is not taking from any other parents here, and there are still plenty more humans to make more humans. Is there a hidden fear here that having an enjoyable childless life will somehow spread everywhere and we all die in a generation?
