International Mountain Day 2025: Theme and Significance
International Mountain Day is celebrated every year on December 11.
It was started by the United Nations in 2003 to help people understand how important mountains are.
Mountains give us water, food, and minerals, and they are home to many different plants and animals.
They also have unique cultures and traditions.
This year, the theme is about how glaciers, which are like big ice rivers, are very important for water, food, and the lives of people who live near mountains.
The United Nations says that glaciers are melting too fast, which can cause big problems like floods and landslides.
They want us to protect mountains and the people who live there.
International Mountain Day is celebrated annually on December 11 to raise awareness about mountain ecosystems.
The United Nations General Assembly recognized the day in 2003, following the International Year of Mountains in 2002.
Mountains provide essential resources like water, minerals, and agricultural products and are home to 15% of the world's population.
The theme for 2025 is 'Glaciers matter for water, food and livelihoods in mountains and beyond', highlighting the critical role of glaciers.
Rapid melting of glaciers threatens agriculture, clean energy, water security, and the lives of billions of people.
