地球是人類的共同家園，然而，隨着科學技術的發展和經濟規模的擴大，全球環境狀況在過去30年裏持續惡化。以下是地球日的由來及意義介紹，歡迎閱讀。
世界地球日的由來
地球日是在環境污染日益嚴重的背景下產生的。世界地球日活動起源於美國。1970年4月22日，美國首次舉行了聲勢浩大的“地球日”活動，這一天，全美有2000多萬人，10000所中國小，2000所高等院校和2000個社區及各大團體參加了這次活動。人們通過舉行集會、遊行、宣講和其他多種形式的宣傳活動，呼籲所有人都行動起來，保護和拯救我們的地球。這是人類歷史上第一次規模宏大的羣衆性環境保護運動。這次活動取得了極大成功，以後每年的“地球日”也都備受關注。這是人類有史以來第一次規模宏大的羣衆性環境保護運動。
作爲人類現代環保運動的開端，“地球日”活動推動了多個國家環境法規的建立。1990年4月22日，全世界140多個國家、2億多人同時在各地舉行多種多樣的環境保護宣傳活動。這項活動得到了聯合國的首肯。從此“地球日”成爲“世界地球日”。
Earth day was created in the context of the growing environmental pollution. Earth day originated in the United States. On April 22, 1970, the United States for the first time held a huge "earth day" activities, on this day, in the United States has more than 2000, ten thousand people, 10000 primary and secondary schools, 2000 universities and 2000 communities and groups took part in this activity. People are calling on everyone to act, protect and save our planet by holding rallies, parades, speeches and other forms of propaganda. This is the first large-scale mass environmental protection movement in human history. The event has been a great success, and the annual earth day has been followed. This is the first large-scale mass environmental movement in human history.
As the beginning of the modern environmental movement, earth day has promoted the establishment of environmental laws and regulations in many countries. On April 22, 1990, more than 200 million people in more than 140 countries around the world held various environmental protection campaigns. The campaign was endorsed by the United Nations. Earth day became earth day.
世界地球日的意義
地球是人類的`共同家園，然而，隨着科學技術的發展和經濟規模的擴大，全球環境狀況在過去30年裏持續惡化。有資料表明：自1860年有氣象儀器觀測記錄以來，全球年平均溫度升高了0.6攝氏度，最暖的13個年份均出現在1983年以後。20世紀80年代，全球每年受災害影響的人數平均爲1.47億，而到了20世紀90年代，這一數字上升到2.11億。目前世界上約有40%的人口嚴重缺水，如果這一趨勢得不到遏制，在30年內，全球55%以上的人口將面臨水荒。自然環境的惡化也嚴重威脅着地球上的野生物種。如今全球12%的鳥類和四分之一的哺乳動物瀕臨滅絕，而過度捕撈已導致三分之一的魚類資源枯竭。
世界地球日活動旨在喚起人類愛護地球、保護家園的意識，促進資源開發與環境保護的協調發展。從20世紀90年代起，中國在每年的4月22日都舉辦“世界地球日”宣傳活動，並根據當年的情況確定活動主題。2008年，中國確定的“世界地球日”主題與“國際地球年”中國行動的宣傳口號一樣，即“認識地球，和諧發展”。其目的是向社會公衆普及地學知識，加強全社會對地學的認識和有效利用，提高公衆對資源國情的認識，實現人與自然和諧發展。
The earth is the common home of mankind. However, with the development of science and technology and the expansion of economic scale, the global environmental situation has deteriorated over the past 30 years. The data show that since the observation records of meteorological instruments in 1860, the global average temperature has increased by 0.6 degrees Celsius, and the warmest 13 years have occurred since 1983. In the 1980s, the average number of people affected by disasters in the world was 147 million per year, up from 21.1 million in the 1990s. About 40 per cent of the world's population is seriously short of water, and if this trend is not curbed, more than 55 per cent of the world's population will face water scarcity within 30 years. The deterioration of the natural environment is also a serious threat to the wild species on earth. Today, 12 percent of the world's birds and a quarter of mammals are endangered, and overfishing has depleted a third of fish stocks.
The earth day campaign aims to arouse the awareness of human beings to love the earth and protect their homeland, and promote the coordinated development of resource development and environmental protection. Since the 1990s, China has held a "earth day" campaign on April 22 each year, and the theme of the event is determined according to the current situation. In 2008, the theme of "earth day" in China was the same as the slogan of "international earth year", namely "understanding the earth and developing harmoniously". The aim is to popularize the knowledge of earth science to the public, to strengthen the understanding and effective utilization of the whole society, to raise public awareness of the national conditions and to realize harmonious development between man and nature.
