M: Hi Daphne, what are you busy with today?
W: Just some assignments after class.
M: I’m going for a car race. Would you join me? Come on!
W: Oh Roger, do you really find car races fun to go to? It’s incredibly boring just watching the cars go around and around the track, and I can hardly breathe because of all the smoke and fumes!
M: You aren’t having fun? Daphne, car racing is the most popular sport in America.
W: I hate cars. They make so much pollution, which is creating holes in the ozone layer. And the environmental problems are only getting worse with global warming!
M: Daphne, cars are a part of American culture. Americans have always relied on cars instead of making do with public transportation.
W: Sorry, but what do you mean with making do with public transportation?
M: Oh, when you "make do" with something, that means you accept it reluctantly.
W: OK, I see. But, Roger, it’s often difficult to see how your lifestyle impacts the world. But we need to prevent pollution by driving cars less and investing in renewable energy.
M: Why do you like the environment so much? It’s full of mosquitoes that want to bite you, and bears that want to eat you!
W: If you’re not nice to nature, nature won’t be nice to you. If the polar ice caps melt, ocean levels will rise and flood the coastal cities.
M: Oh Daphne, that isn’t going to happen. You watch too many movies.
W: Roger, most scientists agree that global warming is real, and evidence shows that the polar ice caps have been melting.
M: Well, what do you want me to do about it? I’m just one person. What can I do to make a difference?
W: Well, to start, you could buy more energy-efficient appliances. You could also think about buying an electric or hybrid car.
M: But I don’t have enough money for that!
W: But all of us are responsible for the environment, aren’t we?
M: Alright, Daphne. You’ve convinced me. I need to do more for the environment. I’m going to stop washing my clothes in the laundry machine to save electricity, and stop taking showers to save water.
W: What? Roger, there’s no need to go crazy, you know.
M: But Daphne, I have to do my part to save the environment! I’m going to "recycle" my dirty socks and wear them over and over again.
W: Roger, in that case the disgusting gasses given off by your body are going to make a bigger hole in the ozone layer than all the cars in the world combined!
