1.
A: Do you know why dinosaurs became extinct?
B: One theory said their extinction was caused by climate change, which affected their source of food.
A: I don’t quite understand.
B: Scientists said there was a severe ice age. The Earth’s water became frozen, so the trees and plants died. Dinosaurs were unable to survive in such conditions.
2.
A: Where can we find rhinos and elephants?
B: Mostly in national parks in Asia and Africa. Why do you ask?
A: Peter and I are going to give a presentation about how to protect them. We suggest that wildlife habitats be better preserved. What’s your opinion?
B: Well, I think we should have better law enforcement to stop the poaching and trading in their products.
3.
A: It was said on TV that the coral in the Great Barrier Reef in Australia and some other places is turning white.
B: Did they say why?
A: Because the sea water is becoming warmer, which kills the algae that live on the coral and bring fantastic colour, as well as food, to this species.
B: Another impact of climate change, isn’t it?
