introduction for study

Overview

I need an introduction for a research paper on "How does pollution affect mammal species richness?" . The instructions and rubric are below. Also, I have attached an old assignment where we initially pitched our research project. However, the introduction must be written in a completely unique way, without using the exact wording or structure from the pitch. All group members have the same pitch, so the introduction must be distinct. The writing should be clear, engaging, and logically structured to effectively lead into the research topic.
