The footprints of mathematics can be seen in every part of environment. The examples of fractal geometry, fibonacci series and golden ratio can be seen in nature directly. Mathematics and environment relationship does not only depend on the physical similarities; mathematics is also a really important tool for understanding the nature. In this research the role of mathematics and mathematical modeling on ecology and environmental problems will be explained. Mathematics plays a key role in environmental and ecological studies because modeling, statistical techniques, and all other applications of mathematics are used to understand the current situation and help to predict future conditions. Thus, mathematics is a really important tool for solving environmental and ecological problems.
