"For the past 10-15 years, the number of protected areas, national parks and nature reserves have increased dramatically in the country. Some years ago, the residents of the regions killed wild animals to protect their livestock from predators. To protect the wild nature the government pays compensation to residents who suffered losses, with the condition that they will not kill wild animals any more. For the past 4-5 years the government have conducted several projects on modernization and reconstruction of water mains and sewer lines in rural areas located on the banks of these rivers. Special equipment cleans waste waters, and sewage water do not dump directly into these rivers"
