The area of green was reducing in the last decades because of the profits that human being chased. Though the government has carried some policies to protect the forest and return part of the green, our environment has been still damaged badly. For example, the national treasure giant panda is dying out. One of the main factors is the lose of conservation areas. In the 1990s, people cut trees for making living, which destroyed the forest and giant panda lost their living places, so the number is falling down all the time. Spanish government advocated March 21st as the World Forest Day. They meant to call for the public to protect the forest. In deed, we need such a day to remind us of the importance of green. If we lost it, then not only animals but also human will die out. 因爲人類追逐利潤，綠植面積在過去的幾十年裏逐漸減少。儘管政府實施了一些政策來保護森林並且綠植面積有所回升，但是我們的環境仍然被嚴重破壞。例如，國寶大熊貓面臨滅絕，其中一個主要原因是失去保護區。20世紀90年代，人們爲了生活，砍伐樹木，破壞森林使得大熊貓失去了生活的地方，所以大熊貓的數量正在下降。西班牙政府提倡把3月21號作爲世界森林日，他們旨在呼籲大家保護森林。實際上，我們也需要這樣的一天來提醒我們綠色的重要性。如果我們失去了它，那麼不僅動物，人類也會滅絕。
