When it comes to the tree-planting day, everybody knows its 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。植樹節最先是爲了紀念孫中山先生的'。孫先生一直很重視植樹造林，在1914年，他頒佈了我國歷史上第一個《森林法》。政府和普通羣衆便開始在春天植樹造林。在1925年3月12日，孫中山先生病逝，爲了紀念他對中國所作出的偉大貢獻，政府把每年的3月12日定爲植樹節。
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. Its 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; its the key to maintain the balance.
