حوار بين شخصين عن البيئة؟

Teacher: Today we studied the environment and how to conserve it
Student: How do we preserve it?
Teacher: In order to preserve the environment we must not throw garbage on the street, not burn trees and not pollute the water
Student: Is this just enough to conserve the environment?
Teacher: Of course not, because there are many things, for example, factories must dispose of production waste in ways that do not pollute the environment.
Also, cars and machines should not pollute the environment either
