Human impact on the environment is a topical issue. Climate change caused by human activities has become a pressing problem. Geography lessons include standard education about the environment and interactive teaching methods using modern information technology. The lessons are set up to test and develop students' skills and knowledge of the effects of climate change and show the choices each person can make to reduce the negative impact on the environment. This is done by reducing greenhouse gas emissions and better understanding of the use of natural resources. A concept of a green island is used to understand the factors that affect the environment.
