5. Create a script of dialogue that could occur between a
harkovskaia [24]

Answer:

Pauline and David are talking about the use of resources in a sustainable manner so that both humans and living organisms can co-exist and enjoy the benefits of nature. Pauline is a conservationist whereas David lives in a biodiversity hot spot. The conversation starts when David and Pauline meet in an ecology conference. Pauline is standing in front of poster talking about conservation of environment and wildlife. David pass by and see that the topic is quite interesting.

David: Hey, I like your topic of presentation.

Pauline: Thank you! are you also a conservationist?

David: I wish I could be but my job nature doesn't allow me to work in this area. However, I truely care about the wildlife which are being threatened in my neighbourhood...

Pauline: Oh, I am sorry to hear that... Where do you live?

David: I live between the city and forest, which is being affected by humans interventions. I see everyday a lot of animals dying on roads because they are forced to migrate because of forest cutting, however, while doing so, they are killed by human's actions.

Pauline: I absoultely hate this behavior of humans. I think human's should understand the importance of other organisms in biogeochemical cycles otherwise our generations are going to pay a lot for this.

David: Definitely, I wish we could reverse such decisions but again, they are not easy. With growing human's populations, we need to adjust everything accordingly.

Pauline: You are right. But we can develop strategies where both humans and animals can live in hormony, such as development of ecological corridors in a forest if we want to make a road, could help these creatures to survive well.

David: I cannot agree more. I hope such things are encouraged in near future. But I really liked your idea and would like to discusss sometime later.

Pauline: Sure, you can visit me anytime in my office at XYZ location.

David: Thank you, see you than!

Pauline: See you!
