Sustaining life on earth system through clean air, pure water, and fertile soil

Soil Air Water CLEAN

Plants + soil/wetland microbes: Food crop systems that also clean air and water

The limitations that will govern bioregenerative life support applications in space, especially volume and weight, make multi-purpose systems advantageous. This paper outlines two systems which utilize plants and associated microbial communities of root or growth medium to both produce food crops and clean air and water. Underlying these approaches are the large numbers and metabolic diversity ...

Why Is Clean Air Clean?

Air exhibiting very low concentrations of light-scattering aerosol particles is occasionally observed even in industrialized regions. Evidence is presented that this very clean air results from highly efficient removal of aerosol particles coupled to the removal of water in precipitation.

Preface to Volume 15 Sustaining Life on Planet Earth: Metalloenzymes Mastering Dioxygen and Other Chewy Gases

In this volume of the Metal Ions in Life Sciences series the mastering of dioxygen (O2), methane (CH4), and ammonia (NH3) by mainly manganese-, ironand copper-dependent metalloenzymes and their biomimetic complexes is discussed. It is closely related to Volume 14, The Metal-Driven Biogeochemistry of Gaseous Compounds in the Environment, which deals with the biogeochemistry of gases including di...
