This chapter analyzes the results of social research on environmental consciousness of Yakut people. Environmental consciousness regulates people’s behavior in ecologically significant situations. Results of the sociological survey show that local people of Yakutia observe some changes in environment, caused by intensive industrial development and global changes in the nature. Changes in the nature such as the climate warming in the winter, flooding because of a high water during spring, and watering of meadows and forests are something that the local people stress special attention to. Climate warming also affects the daily life of northerners. Local people notice some changes in the state of health, conditions of traditional housekeeping, etc. Social studies show that global changes in nature gradually begin to affect daily life of the inhabitants of extreme north and influence their environmental consciousness.
