In recent years, people have removed from the principle of “hand in hand with nature” and have unconsciously
used the sources found in nature by damaging nature. This situation has led to the emergence of a series
environmental problems such as unplanned urbanization, global warming, decaying the natural life, ozone layer
depletion, greenhouse, increasing solid wastes, nuclear pollution, decreasing green areas, destruction of plant and
animal species (Mert, 2006).
