The organisms are able to contribute to numerous natural cycles, they give the material for the formation of soil, affect the composition of the atmosphere, and all of that has huge impact on how the environment looks and what it can provide.

2. The humans have had huge impact on the environment, both bad and positive. Unfortunately, the bad effects are the dominant ones, and they include pollution of all spheres, destroying the environment in order to free space for their own needs, changing the environment in accordance to their interest without taking in consideration the long term done. From the positive side, the humans have managed to transform multiple arid and semi-arid regions and make them green, bring water in places where it has been lacking, stop the major wildfires.
