We, are deeply concerned about the proposed construction of a hydroelectric power plant at the source of the Una River, which is alarmingly close to a UNESCO protected national park. We urgently call upon the relevant authorities to take immediate action to halt this project for the following reasons:

• Environmental Impact: The project has not been thoroughly investigated for its long-term environmental impact on the Una River and the surrounding ecosystem. The construction and operation of the power plant pose a significant threat to the biodiversity and natural beauty of one of Europe's most important rivers.
• Public Health: Citizens living near the source of the river are already experiencing undrinkable water since the project commenced. This raises serious concerns about the potential for further degradation of water quality, which is vital for the health and well-being of local communities.
• Sustainable Development: The potential ecological disaster and the irreversible damage to the Una River far outweigh any short-term economic benefits. The project undermines the principles of sustainable development and the preservation of natural resources for future generations.
• Heritage and Tourism: The Una River is a cherished natural heritage site and a key attraction for tourism. Its destruction would not only affect the local economy but also deprive future generations of its intrinsic and ecological value.

We, therefore, urge the relevant authorities to:

1. Halt the Construction: Immediately suspend all construction activities related to the hydroelectric power plant at the source of the Una River.
2. Conduct a Comprehensive Environmental Impact Assessment: Ensure a thorough and transparent evaluation of the project's potential impacts, involving local communities, environmental experts, and international bodies.
3. Prevent Future Developments: Implement strict regulations and protections to prevent any future projects that could threaten the Una River and its surrounding ecosystem.
4. Ensure Long-Term Protection: Establish a permanent conservation status for the Una River to safeguard its natural and cultural heritage for generations to come.
