It is not possible for human beings to survive on their own. Human beings have maintained their existence in close relationship with their environment since their creation. He needs his environment in order to continue his existence. In the beginning, he met his compulsory needs from his environment and thus continued his life. However, with the progression of time, their needs and desires have changed and in this context, the way they use their environment has changed. It has used the natural resources of the planet as if they were unlimited resources and destroyed nature. Although the consequences of the destruction of the environment first emerged regionally, over time it started to be seen all over the world. Many problems such as difficulty in accessing clean water, famine, epidemics, global warming, etc., which arise as a result of environmental destruction, have begun to threaten the sustainability of living life and our planet. Environmental problems are global problems that affect all people without discrimination. In this context, every individual living on this planet has a responsibility towards the environment. The most basic way to raise environmentally aware and responsible individuals is to provide individuals with effective and efficient environmental education. With an effective and efficient environmental education, it is aimed to raise individuals who have the right knowledge and skills about the environment, are sensitive to environmental problems, exhibit environmentally friendly behaviors, and adopt environmental protection as a lifestyle.
