莱泰亚森林，多瑙河三角洲，罗马尼亚 (© Wild Wonders of Europe/Widstrand/Nature Picture Library)联合国粮食及农业组织估计，每年约有2470万英亩（约1000万公顷）的森林被砍伐。

如果地球有一支“维护团队”，森林一定会冲在最前线。

它们吸收碳排放，减少水土流失，保护生物多样性，影响降雨，并帮助维持清洁的水源。

目前，森林仍覆盖着全球约31%的陆地面积，但其持续减少表明，这些自然系统正变得愈发脆弱。

大片森林仍在被开垦，用于农业生产、基础设施建设和资源开发，使生态系统以令人担忧的速度不断削弱。

国际森林日定于每年3月21日，由联合国于2012年设立，旨在提高公众意识并推动切实行动。

各国政府、组织和社区通常通过植树造林、分享研究成果以及推广可持续森林经营等方式来纪念这一天。

为什么这一天如此重要？

因为森林的健康状况直接关系到气候稳定、生物多样性保护以及全球粮食安全。

今天图片中展示的罗马尼亚莱泰亚森林，正体现了保护行动的实际成果。

它是多瑙河三角洲生物圈保护区的一部分，生长在由水流与风力长期塑造而成的海洋沙质地貌上。

保护像莱泰亚森林这样的森林，有助于确保后代能够继承依然稳固、持续运转的生态系统。

International Day of ForestsThe UN FAO estimates that about 24.7 million acres (10 million hectares) of forest are cut down each year.If Earth had a maintenance crew, forests would be spearheading it. They absorb carbon emissions, reduce soil erosion, safeguard biodiversity, influence rainfall and help maintain clean water supplies. They still cover about 31% of the world's land area, yet their continued decline shows how vulnerable these natural systems have become. Vast stretches continue to be cleared for agriculture, infrastructure and resource extraction, weakening ecosystems at an alarming rate.The International Day of Forests, observed every March 21, was established by the United Nations in 2012 to raise awareness and inspire meaningful action. Governments, organisations and communities mark the day through local action—planting trees, sharing research and promoting sustainable forestry.Those actions take on added meaning in forest nations like Canada. From community tree-planting to protecting old-growth ecosystems, stewardship here helps sustain carbon storage, biodiversity and the livelihoods that reach far beyond national borders.点击下方阅读原文，获得更多精彩内容扫码关注每日更新扫码进入微信小程序，每天0点准时更新
