Why are Mountains Important?

Mountains cover nearly a fourth of Earth's land surface and are shaped by tectonic forces and volcanic activities. Their slopes capture rainfall, replenishing aquifers and sustaining most of our freshwater needs.
These water towers also comprise half of the world's biodiversity hotspots. Their unique climate, shaped by altitude and exposure, makes them a refuge for species that cannot be found anywhere else on Earth. Unfortunately, up to 84% of endemic mountain species will face extinction if the global temperature continues to rise.
Surprisingly, these steep slopes are home to about 22% of the global population. The Food and Agriculture Organization (FAO) reports that approximately 90% of people living in mountainous areas reside in developing countries. However, almost one in two mountain dwellers faces food insecurity.
In addition, mountains shape our weather patterns. They act as natural barriers and influence rainfall and wind flow.
Climate change is melting mountain glaciers faster than ever, increasing the risk of landslides and floods, which affect all inhabitants. Additionally, unchecked tourism can damage the land and strip it of its biodiversity.
How to Take Care of Mountains

- Join clean-up drives in mountainous areas.
- Practice "Leave No Trace" principles.
- Reduce your carbon footprint to mitigate climate change.
- Support local economies in discouraging illegal logging and poaching.
- Advocate for mountain conservation.
- Support policies and legislation to protect mountain ecosystems.
