b. Imagine that you are a scientist who studies water ecosystems. Write an email to your local/regional government giving suggestions to help protect these ecosystems.

Solución: Subject: Urgent Recommendations for Aquatic Ecosystem Preservation Dear Members of the Regional Council, I am writing to you as an aquatic ecologist currently researching our local rivers and wetlands. Over the past five years, our scientific team has observed an alarming decline in biodiversity due to rising pollution levels and habitat fragmentation. To reverse this critical trend, I would like to propose several immediate actions. First, the administration should enforce stricter regulations on agricultural runoff, particularly chemical fertilizers and pesticides that cause excessive algal blooms. Second, investing in upgraded wastewater treatment facilities is essential to prevent untreated industrial discharge from reaching freshwater basins. Finally, establishing protected buffer zones along riverbanks would naturally filter pollutants and protect native wildlife. Protecting these vital ecosystems requires decisive political leadership. I remain at your disposal to discuss these scientific proposals in further detail. Yours sincerely, Dr. Alex Evans Senior Aquatic Ecologist
