1. Mountain environments are important but also face threats from climate change, land degradation, pollution, and overtourism.
2. Conservation efforts include using renewable energy, reducing waste, promoting eco-friendly infrastructure and practices, and ensuring local economic benefits from tourism.
3. Achieving "leave no trace" and "zero waste" goals in mountain areas is challenging due to lack of waste management infrastructure and decomposition issues at high altitudes.
4. All stakeholders including local communities, tourists, guides, and governments must work together and take responsibility to protect mountain environments through sustainable practices.
