Brenda: Look at this headline, Steven! "Childhood cancer due to polluted living environment."
Steven: Really? (1) Is it true that pollution causes deathly diseases?
Brenda: It's not strange to me now. Humans have polluted the environment for a long time, so they suffer the consequence.
Steven: (2) That must be some solutions to this.
Brenda: Well, there have been lots of researches proving that polluted air and contaminated food chain are linked to several diseases including lung cancers, cancers of the digestive organs, and heart attacks.
Steven: (3) Moreover, the area will also be polluted someday if you don't protect it. I've read about that kind of news for many times.
Brenda: Pollution can even lead to other dangerous things such as global warming and natural disasters.
Steven: Oh, I've read some articles about the relation between climate change and some natural disasters, it's real and considerable.
Brenda: We can choose to live in unpolluted areas, or we should help together to reduce the pollution.
Steven: (4) Living in an unpolluted area? It seems ideal, but most of the unpolluted areas are located in remote regions. So the better solution is the second one - reducing pollution to protect the environment.
Brenda: I really hope so. Then we all will have healthy life.
Steven: (5) Yes, I think everybody knows it. I believe dangerous things like cancers or disasters will decrease when the world becomes greener.
