这棵树是个快乐的家伙！ For tree's a jolly good fellow

生命之树，华盛顿州，美国

美国第一个植树节是在1872年举行的，从那以后，这项活动真正地生根发芽。每年四月的最后一个星期五，美国各地的人们都会通过植树来纪念这个节日，通常会把这些树献给所爱的人。这一天也是纪念树木的好日子——树木不仅为无数种动物提供家园，还能吸收二氧化碳，净化我们呼吸的空气，帮助城市保持凉爽，甚至还能起到预防洪水的作用。

图中这棵神奇的树是位于华盛顿州福克斯的卡拉洛奇生命之树。这棵大型西提卡云杉的根系似乎不受地心引力的影响，紧紧贴在一条小沟壑的两侧。树下的土壤正在被流入太平洋的溪流慢慢冲刷，但不知何故，生命之树仍在继续生长。鉴于它的生命意志，不难理解这棵树是如何赢得这个绰号的。

Arbor Day

The first Arbor Day in the US was held in 1872. Since then, the event has really taken root. On the last Friday of April, people across the country mark the occasion by planting trees, often dedicating them to a loved one. It's also a great day to celebrate trees themselves. As well as providing homes for countless species of animals, trees absorb carbon dioxide and clean the air we breathe. They also help to keep cities cooler and can even play a role in preventing floods.

The amazing tree in today's image is the Tree of Life at Kalaloch Beach on Washington's Pacific coast. Seemingly defying gravity, this large Sitka spruce's roots cling to the sides of a small gully. The soil under the tree is slowly being worn away by a stream that flows into the Pacific Ocean, yet, somehow, the Tree of Life continues to grow. Given its will to live, it's easy to understand how this tree earned its nickname.
