When it comes to the tree-planting day, everybody knows it’s a day that call on people to plant more trees and stop cutting down trees blindly, but few people know the story behind tree-planting day. The tree-planting day was dedicated in the memory of Sun Yat-sen. Mr. Sun had always pay great attention to trees planting. In the year of 1914, he promulgated the first Forest Law in history. Then the government and the ordinary people started to plant trees in the spring. On March 12th, 1925, Mr. Sun passed away, in order to memorialize the great contribution he had make to our country, the government decided every year of this day is the tree-planting day.
當提到植樹節，人們都會聯想到這是一個號召大家種植更多樹木，停止盲目砍伐樹林的節日。但是鮮有人知植樹節的由來。植樹節最先是為了紀念孫中山先生的。孫先生一直很重視植樹造林，在1914年，他頒布了我國歷史上第一個《森林法》。政府和普通群眾便開始在春天植樹造林。在1925年3月12日，孫中山先生病逝，為了紀念他對中國所作出的偉大貢獻，政府把每年的3月12日定為植樹節。

In 2014, the slogan of tree-planting day is Embrace the spring, Sow the Green. Trees are so important to our planet. The naturalists compare the trees to human beings lungs. It’s true that trees take in the carbon dioxide and other toxic gas and give off oxygen which living beings lives on it. If trees were all cut down, the earth would be a disaster. First of it, the temperature will raising then the glaciers will melt. Thus the cities near the ocean will be flooded. Second, the trees are the habitat of many animals. When we cut down trees, we not only destroy animals’ habitats but also ourselves’. We just gradually destroy natural links. Last but not least, trees can prevent water loss and soil erosion; it’s the key to maintain the balance.
在2014年，植樹節的主題是“擁抱春天，播種綠色”。樹木對我們的地球來說非常重要。自然學家甚至把樹木比作人類的肺部。樹木能夠吸收二氧化碳和其他有毒氣體，并轉化成生物們賴以生存的氧氣。如果把樹木全部砍掉，那么地球就會陷入災難之中。首先，氣溫會升高，然后冰川就會融化，導致近海的城市會被海水給淹沒。其次，很多生物把樹木當成自己的棲息地。當我們砍伐樹木時，我們也破壞了自己的家園。生物鏈就慢慢被我們給瓦解了。最后，樹木能阻止水土流失。它是保護生態平衡的關鍵。

Trees are so important for living beings. Eighty nine years has passed by, we still marvelous at Mr. Sun’s foresight and wisdom that he knew planting trees and protect the environment is the foundation of developing a strong and wealthy country.
89年過去了，我們依舊感嘆孫中山先生的遠見和智慧——他認為植樹造林、保護環境才是強大國家、富裕人民的基石。
