解析
【分析】首先明确本题是八年级英语应用文（演讲稿）写作题，主题为“Protect Our Ecosystems”，需紧扣三个写作提示展开：①阐述生态系统对地球和人类的重要性；②说明当前生态系统面临的问题；③列举学生可采取的保护措施。写作时需以一般现在时为主，用第一人称，词数控制在80-100，还要运用给定的亮点词块（如provide sb. with sth.、because of等）和高分句式（如without引导的条件句），结构需清晰：问候→重要性→问题→学生做法→呼吁→致谢。
【解析】写作步骤如下：1. 开头问候听众，点明主题；2. 阐述生态系统的重要性：用“provide us with...”说明其提供清洁空气、淡水、食物及调节气候，再用高分句“Without healthy ecosystems, humans and animals cannot survive”强化重要性；3. 说明生态系统面临的问题：指出因污染和气候变化，动物失去家园，处境危险；4. 列举学生的做法：节水节电、种树回收、不买濒危动物制品，用“make a big difference”强调小行动的作用；5. 发出呼吁并致谢，控制词数符合要求。
【答案】Protect Our Ecosystems
