A better (and almost as pithy) slogan would be "Save our Earth" - the one with the current coastlines, biosphere, atmospheric composition and inhabitants.
Thus far, we have seen that the biosphere, by structure, composition, and physical makeup, is completely enclosed by the domain of life, which has so adapted itself to biospheric conditions that there is no place [on Earth] in which it is unable to manifest itself in one way or another.
The terrestrial biosphere regulates atmospheric composition and climate by altering the exchange of energy, water and trace gases between the surface and atmosphere1.
The biosphere, though primarily H2O in composition, contains very little of the total water at the terrestrial surface, only about 0.00004 percent, yet the biosphere plays a major role in the transport of water vapour back into the atmosphere by the process of transpiration.
Micro-organisms regulate the chemical composition of the biosphere, influence climates, recycle nutrients, and decompose pollutants.
As we pointed out earlier, the biosphere can strongly affect the atmospheric composition.
Bacteriophages are the most abundant biological entities in our biosphere, characterized by their hyperplasticity, mosaic composition, and the many unknown functions (ORFans) encoded by their immense genetic repertoire.
Spatially explicit model predictions of the isotopic composition of leaf water and other biosphere and atmosphere pools have been made for some time using various platforms and approaches [5], [6], [7].
In doing so, they aim to define a new paradigm for investigating changes in the atmosphere by integrating the microscopic mechanisms of chemical, physical, and biological processes with large-scale ecological and geological interactions between the geosphere, biosphere, and oceans, and how these interactions alter atmospheric composition.
it would be much enhanced if it turned out to be true the suggestion made by Tommy Gold - in his book "The deep, hot biosphere" - about the carbon dioxide, which is predominant in the composition of volcanic gases.
On the other hand, studies comparing the rare biosphere across different ecosystems should be handled with caution, since the composition of the rare biosphere within a specific ecosystem appear to vary significantly between seemingly identical samples, and hence a single sample is not truly representative of the rare biosphere of the entire ecosystem [9].
