Protect Our Earth
　　Mahatma Gandhi ever said that "Earth provides enough to satisfy every man's need, but not every man's greed." Simple as the motto may sound, it conveys a thought-provoking notion that each of us has no any reason to exploit natural resources of the Earth recklessly and excessively though the natural resources of the world are abundant enough to meet the need of human beings.
　　We have only one Earth. How to tackle the problem of protection of environment and Earth and how to save energy effectively is crucial to our increasingly modernized society. The rapid development of economy shouldn't be based on the price of deteriorated environment. Saving such resources as water, oil, gas, coal and wood could ensure the sustainable development of the society and environment. Otherwise, these resources would be exhausted one day and nothing would be left for the future generation.
　　In a word, it is imperative for us to cherish and protect the nature for the benefit of next generations and ourselves. We should effectively protect, rationally exploit and economize on natural resources. Only in this way can we embrace a green, harmonious, abundant and beautiful world.      (196 words)

保护我们的地球
　　圣雄甘地说过"地球能满足人类的需求，却满足不了人类的贪婪。"这个格言道理很简单，它发人深思地告诉我们：尽管我们生活的世界自然资源丰富得足以满足我们人类的需要，但是，我们每个人都没有任何理由不顾后果地、过度地开发自然资源。
　　我们只有一个地球。如何保护环境和保护地球，以及如何高效地节省能源，对我们发展日益现代化的社会是个迫在眉睫的问题。经济的迅猛发展不应以环境恶化为代价。只有节约像水、石油和天然气、煤炭和木材这样的自然资源才能确保社会和经济的可持续发展。否则，这些自然资源终将有一天会消耗殆尽，我们也不能为子孙后代留下什么。
　　总之，为了下一代，为了我们自己，珍爱地球、保护自然刻不容缓。我们应该高效保护、合理开发以及节约利用自然资源。只有这样，我们才能拥有绿色、和谐、富足和美丽的世界。
