Welcome to UsingEnglish.com.
First, I see your title is written in capital letters.
I'd like to suggest that you shouldn't do it, as it will be considered as the online equivalent of shouting.
Are you a student? I think your dialogue is good though it contains some grammatical mistakes.
(It is understandable to me, at least, except for 'reboisation'.)
Now, I will leave it to native speakers to correct it.
