Read the following passage carefully:
During a recent summer, I had the opportunity to visit an extraordinary botanical garden. It was not just a place to admire flowers and trees but a vibrant ecosystem showcasing the harmony between nature and human creativity. Each section of the garden was meticulously designed to reflect different climatic zones, featuring exotic plants from around the world. While walking through the garden, I was particularly struck by a section dedicated to endangered species. This area not only highlighted the beauty of these plants but also served as a reminder of the urgent need for conservation efforts. The informative plaques provided fascinating facts about each species, including their natural habitats and the threats they face. By the time I finished my tour, I felt an overwhelming sense of responsibility towards the environment.
