The Earth's biosphere, which includes all living organisms, is essential for maintaining the planet's habitable conditions from "summary" of Earth System Science by Timothy Lenton
The biosphere of Earth is a complex web of living organisms that interact with each other and with the physical environment. This interconnected system plays a crucial role in maintaining the planet's habitable conditions. Without the biosphere, Earth would be a barren and lifeless rock, unable to support the diverse array of life forms that currently inhabit it. One of the key functions of the biosphere is to regulate the composition of the atmosphere. Through processes such as photosynthesis and respiration, plants and other organisms help to maintain the balance of gases like oxygen and carbon dioxide. This balance is essential for supporting life on Earth, as many organ...
