Letea Forest, Danube Delta, Romania

Where roots run wild. International Day of Forests

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 21 March, was established by the United Nations in 2012 to raise awareness and inspire meaningful action. Governments, organisations and communities mark the day by planting trees, sharing research and promoting sustainable forestry. Why does it matter? Because forest health directly supports climate stability, biodiversity protection and global food security.

Romania's Letea Forest, featured in today's image, highlights conservation in action. Part of the Danube Delta Biosphere Reserve, it grows on marine sand formations shaped by shifting waters and winds. Safeguarding forests like Letea helps ensure future generations inherit ecosystems that still endure.
