Geography and biology hold very important places among the natural sciences. Geography can be divided into physical geography, human geography, and regional geography, while biology can be divided into molecular biology and cell biology, genetics and evolution, and homeostasis and the environment. Therefore, as members of humanity in the 21st century, we need to understand the environment we inhabit, as well as the other living things that share it with us. Only then can we live in harmony with our surroundings and coexist with all living things, maintaining the balance of the biosphere in harmony.
