Conversation 2
Man: Hey, what are you reading?
Woman: I'm reading how cows contributes to climate change.
Man: Cows! How do they do that?
Woman: By releasing methane gas into the environment.
Man: But, they're cows! I don't see how they can do that.
Woman: They release gas by burping. It says cows burb a lot.
Man: By burping? How strange.
Woman: It also says that farmers cause damage by cutting down trees to make farmland.
Man: Yes, I've heard about that. Cutting down forests does damage by reducing how much trees can absorb C02.
Woman: Yes, and deforestation is also a problem by causing soil erosion.
Man: So, what can we do about it?
Woman: I suppose that we could help by eating less beef.
Man: Yeah, or we could help by buying meat from local organic farms.
Woman: Sounds good. Time to put our best foot forward.
Man: Yes, and to put our money where our mouth is, literally.
