You can do what?

I imagine pop rushing would be kinda drastic, like taking 8 pop off a 9 pop city, but that's a huge change! It would still be more efficient to have a city concentrate on trying to breed Great Engineers, but this does give the capability to win wonder races -- that is if you have some way of knowing how hard you need to try.
Can you chop, have a forest grow back (that's very cool too) and chop it again?
