6 阅读下列材料，回答问题：（13分） “数字地球”是继哥白尼、伽利略日心说和地理大发现之后，人类认识地球的又一次飞跃。如果说20世纪60年代麦克卢汉提出的“地球村”代表了电气时代对地球的最高认识，那么20世纪90年代提出的“数字地球”是“地球村”在电子时代的升华。在这一升华中，从“模拟”到“数字”是一次突变。“数字地球”是一种国家战略，也是一种技术体系，同时又是一个科学文化概念。它是数字技术和20世纪60年代以来以生态环境保护、可持续发展为核心的文化思潮的结晶。“数字地球”是一个居住在因特网上的以“空间智能体”为主要种群的高级生态系统，也即“数字生态系统”。这一“数字生态系统”将在地球生物圈和技术的战略平衡关系中起到决定性作用。到目前为止，人类已做到了全天候监控地球，但离控制地球的目标还很远。在濒临失衡的地球上，大自然无情地报复我们，“数字地球”将有助于人类监控地球。 (1)“数字地球”被称为“人类认识地球的第三次飞跃”，前两次飞跃的代表事件是? (2) 简述“数字地球”所涉及的关键技术。材料中说“数字地球”是一个科学文化概念，对此你是怎么理解的? (3)“在濒临失衡的地球上，大自然无情地报复我们，‘数字地球’将有助于人类监控地球。”请结合这句话，谈一谈你的看法。
