保护最后一片大荒野 Protecting the last great wilderness

南极日

今天是南极日，让我们将目光聚焦在世界上最引人注目的国际协定之一的《南极条约》上。该条约于1959年由12个国家签署，将整个南极大陆指定为非军事区，特别注重促进科学研究与合作。这一天彰显了全球合作精神，提醒我们肩负起保护地球上最后一片大荒野的集体责任。

“南极洲”这个名字源于古希腊语“antarktikos”，意为北极的对面。公元前350年左右，希腊哲学家亚里士多德首次提到“南极地区”的概念。尽管提及时间很早，但直到19世纪，人类才真正看到南极洲。南极洲是地球上最寒冷、最干燥、风力最大的大陆，气温最低可达零下112华氏度。这里广袤的冰原和冰川蕴藏着全球约70%的淡水。正如图片所示的那样，南极洲的海面上遍布冰山，冰山在南大洋上漂流，随着时间的推移逐渐融化。诸如帝企鹅和阿德利企鹅等物种，以及海豹、螨虫、线虫和水熊虫等生物，都把这片冰冷的栖息地当成了它们的永久家园。

Antarctica Day

Today, Antarctica Day shines a spotlight on one of the world's most remarkable international agreements—the Antarctic Treaty. Signed in 1959 by 12 nations, this treaty designated the entire continent as a demilitarized zone, with a special focus on promoting scientific research and collaboration.. This day honors the spirit of global cooperation, reminding us of the collective responsibility to protect the planet's last great wilderness.

The name 'Antarctica' is derived from the ancient Greek word 'antarktikos,' meaning opposite the Arctic. The concept of an 'Antarctic region' was first mentioned by Greek philosopher Aristotle around 350 BCE but it wasn't discovered until the 19th century. It is the coldest, driest, and windiest of the Earth's continents, with temperatures plunging as low as -112 degrees Fahrenheit. Vast ice sheets and glaciers found here hold about 70% of the world's fresh water. The waters are dotted with icebergs, as seen in today's image, which drift across the Southern Ocean and melt over time. Species like emperor and Adélie penguins, along with seals, mites, roundworms, and microscopic eight-legged moss piglets, call this icy habitat home.
