T: Hang on a minute! I’ll make some notes.
L: When populations increase too fast, it can cause problems,
such as too much traffic and noise.
T: That’s true. How about countries with slow-growing populations
L: Countries with low birth rates have problems too. There aren’t
enough people to do all the jobs, or enough young people to look
after the older ones.
T: I see. Great, thanks for the information! Now I can write my report!
