今年纪念世界地球日,正值日本刚刚发生9级大地震之后,其意义尤为重要。它提示我们:地球不仅仅为人类的生存和发展提供了衣食住行用所需要的空间、物质、能量资源;其活动也能给人类带来巨大的灾难。地球对人类正负两方面的作用,要求我们必须全面了解地球。我们对地球了解得越多、越全面,越能有效地利用地球给我们提供的资源,越能有效地防治地球给我们造成的灾难。
This year’s anniversary celebration of Earth Day is just as important as the magnitude 9 earthquake in Japan. It prompts us that the Earth not only provides space, material and energy resources for the subsistence, development and development of mankind, but also brings about tremendous disasters to human beings. The role of the Earth on both mankind and mankind requires that we must fully understand the earth. The more we know about the Earth, the more comprehensive and the more effective the use of the resources provided by the Earth to us. The more effectively we can prevent and control the disasters caused by the earth to us.
