Mr An: As you see, habitats affect their flora and fauna, but the flora and fauna also affect their habitats.
Mi: Can you be more specific, Mr An?
Mr An: Well, plants can help or harm their environment. For example, when someone brings a plant to a new place, the plant can make the area more beautiful.
Mi: Yes, it does.
Mr An: But that plant can also grow so fast that it takes over the resources of local plants. And these local plants may die out.
Mi: How about animals? Do they affect the environment too?
Mr An: That’s a good question. Similarly, animals can cause harm to or improve a habitat. Beavers, for example, build dams and ponds and this helps plants and animals which need water.
Mi: How do beavers harm the environment?
Mr An: These dams may flood the homes of other plants and animals.
Mi: Ah, yes. So what should we do, Mr An?
Mr An: We should preserve habitats by not bringing plants and animals from different places. We shouldn’t cut down forests because that destroys the habitats of many species, or use pesticides which pollute the environment….
