Why is the theory of the biosphere important for the development of ecology?

The biosphere is the outer shell of the Earth, the area of ​​distribution of life. It includes:
-living substance, i.e. the totality of all living organisms (plants, animals, fungi, microorganisms)
– biogenic substance, i.e. organic products created by living creatures
– bioinert substance
– inert substance (dead).
As you can see, the doctrine of the biosphere is a vast area where it is necessary to understand all the processes occurring with living organisms, their life, etc.
Later, a separate science was singled out – ecology. now this science studies the interactions of living organisms with the environment.
Therefore, it is so important for us to study this area in order to learn how to properly handle nature in order to reduce the human impact on the biosphere.
