The impact of human economic activities on individual natural components or whole geosystems has caused a global environmental crisis and continues to change the surface of the planet beyond recognition. New biospheric thinking is required to overcome the existing threats. For that purpose, the new generation shall possess high ecological culture. The article aimed to examine the problem of formation and development of environmental competence of students based on project technology. The conducted research allowed students to independently identify environmental problems with the help of project technology. Practical development in the form of project tasks contributes to the formation of environmental competence in future biology teachers. The effectiveness of the proposed training technology is confirmed by the results of experimental work.
