The document provides guidance for writing an argumentative essay on whether tourism has a positive or negative impact on the environment. It notes key points about taking a "for" or "against" position. It also suggests questions to consider for the "against" viewpoint and how non-environmental benefits like economic and cultural factors must be tied back to helping the environment. Outline structures are proposed for introductions depending on the stance. Potential topic arguments are listed for both the "for" and "against" positions as well.
