M: What did you do last night?
W: I watched TV.  There was a really good movie called Soylent Green.
M: Soylent Green?
W: Yeah. Charlton Heston was in it.
M: What’s it about?
W: Oh, it’s about life in New York in the year 2022.
M: I wonder if New York will still be here in 2022.
W: In this movie, in 2022...
M: Yeah?
W: ... New York has forty million people.
M: Ouch !
W: And twenty million of them are unemployed.
M: How many people live in New York now? About seven or eight million?
W: Yeah,I think that’s right.
M: Mm, hmm. You know, if it’s hard enough to find an apartment now in New York City, what’s it going to be like in 2022?
W: Well, in this movie most people have no apartment. So thousands sleep on the steps of buildings. People who do have a place to live have to crawl over sleeping people to get inside. And there are shortages of everything. The soil is so polluted that nothing will grow. And the air is so polluted that they never see the sun. It’s really awful.
M: I think I’m going to avoid going to New York City in the year 2022.
W: And there was this scene where the star, Charlton Heston, goes into a house where some very rich people live.
M: Uh - huh.
